    So, has anyone skated in the R1's?

    I play competitive roller and am around the game a good bit, I don't really see much, if any, players wearing Marsblade. Most of the high end roller guys opt for flagship Misison or Bauer skates like FZ-0/2XR Pros.

    I always though of Marsblade as something geared for ice hockey players in the offseason or for training off ice. But it seems like they are now selling them as a game changing, high end roller skate. Haven't seen that bear out much at all yet.

    On our Roller hockey Instagram @marsblade_rollerhockey we have posted several quotes and reviews from world class players about the R1 chassis. Obviously I am not the most objective person to answer this question, but we have now specifically sent chassis to at least 30 of the best players in the world and more or less everyone has changed to R1 with overwhelming feedback. In addition to the above mentioned players, it includes top national team players from around the world like Martin Fiala Czech Republic, Travis Noe and PJ Kavaya USA, Karl Gabillet France, Marcus Fajardo Spain, Juan Pablo Triviño Colombia, Luiz Koenen Brazil, Martin Uhnak Slovakia and many moore 👑

    Any chance that we can get a insert with a little more heel rocker maybe a H4?

    We definitely have plans to offer a bigger variation of settings. And which settings we choose to go ahead with is determined by what you, the players, demand. What I can add from a product development perspective is that the scale of different settings is not linear. The difference between 4 and 5 is quite large, while the difference between for example 14 and 15 is significantly smaller, So inbetween 4 and 5 it is a quite wide range of different skate feels. See image example below. Just to give you a better feeling of the setting numbers 🙂 0fpsNS7.jpeg

    Could Marsblades be mounted on carbon fiber speed skate boots that have aluminum mounting plates at the front and rear? Ideally we would not drill and rivet into the carbon fiber sole (aside from the fiber dust created with drilling into carbon fiber the profile of the bottom of the boots is not flat (it has indentations for large diameter wheels) and I would imagine that the Marsblade chassis would need to be flush with the sole.

    Hi Kyle,

    It sounds difficult since our mounting holes are in the edges of the chassis / boots while the mounting plates on speed skates appear is placed directly under the heel and directly under the toe. It is possible that you can mount them with your own creative solution, for example by drilling your own mounting holes through the chassis. Of course we can not guarantee that it works out in a good way, but if it would be interesting to hear how the chassis works for speed skating, so if you are interested in testing anyway, feel free to contact me in a DM.

    I'm wondering about the optimization of the R1s for roller play, specifically regarding if they will help relieve the stress of play on the legs and knees.


    I know the concept is very different from sprungs, but when I play on sprungs they mitigate a significant amount of fatigue in my legs. I didn't notice until I played two games on sprungs and then played a very light game of pickup in an old pair of hilos. An hour on hi los had my legs more beat the next day than playing 3 hours straight of intense 4 on 4 on sprungs. (I had plenty of rest in between, so that's not a factor). 


    I'm wondering if the flow motion will have a similar effect, where it helps relieve some if the stress and fatigue in the legs. I know that the O1 is meant to work the legs more, so I'm hoping that's not the case with the R1. Any feedback?

    Hi Miller,

    No scientific biomechanical studies have been conducted on this yet, but we are absolutely convinced that the answer is yes - it will help relieve the stress on the legs and knees! Since your foot can have a range of positions while still have full contact with the surface, you can have a much more natural movement during a stride than when your feet are limited to one specific position. I think a relevant comparison is when you run in a pair of running shoes. Since they are rounded and soft, you can land on your heel, "rock" over the foot, and puch away with your toe. If the shoe were completely stiff and flat, like the wheelbase of a traditional inline chassis, it would have a significant limitation on your running technique and natural movement pattern.

    Are there any durability concerns with the inserts? Will this be a component that will wear out and need replacing? If so, what is the expected lifespan and how much will replacement inserts cost? 

    Hi Westside, 
    We had no problem during testing with the durability of the inserts. We do not expect that you need to change the insert because it becomes too worn, but in near future we plan to offer a larger range of different inserts with different settings to make sure all kind of players can find their perfect setting. Spare parts will be available in our webshop.

    Thank you for all the additional answers. Since the R1 requires an insert to change the rocker motion vs the center bolt on the O1, is there a reason an insert that provides maximum mobility can’t be created? IIRC from one of the other posts, the H5 insert is most like ice. Based on the chart on your site, that insert allows maximum heel movement and more toe movement than any other insert. Could another insert be made to have maximum heel movement AND maximum toe movement which would essentially match the movement of the O1? Conversely, I think it would be interesting to also have an insert that would eliminate almost all movement. Obviously not the purpose of the product, but there are times when movement is not desired and rather than having to throw on another pair of skates, you could simply change the insert. 

    You are absolutely right. We have so far produced a series of four different settings that we think match each other and cover a good range of different players' preferences, but this is of course only a minor part of what variations can be made. And in addition to different radii, you can also change things such as balance point, starting position, adding stops, use non-symmetric curves, and so on. What ultimately determines which settings we make is what you players demand. Further on we have a vision to have a whole library of different settings. Another idea is to release open source 3D-files for creative players with some knowledge in 3D modelling to create their own insert settings, for themselves or for sharing with the roller hockey world.

    To answer your questions: with the current construction of R1 it is no problem to make a 5-5 or higher, but technically a little more challenging to go lower than 5-5 and reach O1 movement. But it can definitely be done, and we will work on it if we see a big demand for it. Making an insert with no, or very little movement is technically no problem at all.

    Is there a way to check on the status of an order via Marsblade's site or whatever?

    I pre-ordered the 01+boot package back on May 1st.  I was just curious if there was a way to get an update as to expected ship date.  IIRC when I ordered it said July but ??


    Not before the package is sent and we can provide a tracking number. For pre-orders there is still uncertain times because of the Covid-19 situation, but so far everything looks good and we are on schedule. For more detailed questions about an order you can contact the customer service of Marsblade, store@marsblade.com.

    About to pull the trigger on a set of R1. I've got a pair of Mission skates right now that I like, but am wondering if the rivet pattern will be different enough as to be OK to use with the R1. 

    Also, let's say I don't like the R1, would there be any issue with going back to my old chassis? Not sure if the boot will be too swiss cheese at that point.

    Its not the same hole pattern as Mission, new holes need to be drilled, but having two sets of holes in the boot is normally not a problem at all. Technically it is no problem to take of the R1s and mount back your old chassis again. BUT if you once get used to Flow Motion, going back to your old chassis will feel like putting on a pair of alpine boot 😏

    I'd like a more in depth explanation of the flow motion tech in the r1 compared to o1. In layman's terms obviously. I get the basic idea, but I'd like to understand what you mean by "optimized for game play." Sounds nice, but what exactly is different and what exactly is used to determine optimized? 


    Also, I'm assuming these take floating spacers? 

    When we speak about something is optimized we mean that we have started with a wide range of settings, tested it over and over again, ourself and with our test players, before we narrowing it down and iterate it until we reach the best possible results for what we want to achieve. That is: as ice-like feeling as possible when we developed O1, and maximum performance in roller hockey when we developed R1. We work a lot with 3D printers and can then adjust the settings down one tenth of a millimeter at a time between the tests.

    Parameters we work with are mainly:

    • size of the radius in the toe and in the heel,
    • what angle the chassis should have in the starting position,
    • where the balance point should be,
    • how hard the spring should be,
    • how much pre-tension the spring should have,

    and so on.

    Are there any more videos of the r1 chassis out there? I've only seen John Schiavo and Itan Chavera do short informal ones so far. 

    Its definitely coming, biggest problem is that the Covid-19 made it hard for the test players to get their skates mounted and to get access to rinks. 

    Here is a few though: 

    More is comming!

    Does anyone know whether the large O1 chassis can accommodate 80mm wheels? I'm thinking of doing a 76/80/80/76 setup

    No, 76 is the biggest possible wheel size on large. And I would personally suggest that testing with a looser centre bolt, or testing with advanced wheel setup, is better ways to go to get more imbalance.

    My question for @Marsblade is why the fixed axis 01 feels more like ice and why adjusting the R1 movement to suit your skating style makes the R1 feel less like ice, because adjusting the movement seems like the same thing as profiling steel runners to suit your skating style on ice. Why wouldn't the R1 just feel like skating on ice on a custom-profiled blade?

    So far, they feel really good...extremely smooth and already much better and less cumbersome than traditional chases even with the bolt fully tightened. (I'm using some ABEC 11 bearings instead of the ABEC 9 they come with, but that probably doesn't make much of a difference.)  It's definitely much more like skating on ice and wheels no longer feel like I'm on skis and my skates no longer fight against some of what my feet are trying to do. But I wouldn't say that they "force" me to do anything different (which is the way MB refers to it); it's much more like they just allow me to skate much more like I normally skate. My quads do get more involved, but I don't notice it until I'm done and they feel sort of like I just did a light leg workout.   

    Maybe when I open it more, I'll understand what MB means when they say the 01 force you into better skating mechanics. I've only opened the bolt about 1 full turn so far, maybe a little less...I only open it about 60 degrees after each time I skate. Whenever I first get back on them after opening the bolt a little more, it feels like my weight is too far back on my heels for a few seconds until I get used to it. The reviews I've watched suggest the exact opposite: that they put you more on your toes and that new users feel like they're going to face-plant. 

    Another question for @Marsblade is you've said (here and in promos) that the smaller front wheel provides more of a challenge. Could you explain what you mean by that and what's different about skating on the advanced set-up? I'm not planning on trying it until I'm comfortable with the loosest bolt setting, but I'm curious how you'd characterize the difference made by the smaller front wheel. 


    Short answer on your first question is that O1 was not made for performance, which means we can have a smaller radius than what is optimal for maximum performance. And a smaller radius means more movement and in the end a more ice-like skate feel. What we found out during the development of the R1 was that optimal for maximum performance is to still have a significant amount of movement, but not as much as in O1. We also found out that two different players can have very different preferences for what settings they prefer, even if they are both top elite players, why we decided to make it customizeable. 

    I mainly leave the advance wheel-setup question for Per, but what i can say is that it put higher demands on the player's balance and gives an even more ice-like feel. Waiting until you feel comfortable with the standard wheel setup sounds sensible, but beyond that, we definitely recommend testing it!

    Hi Petter

    Can I ask a question not related to the post but since your in the development team i thought I’d try & sneak it in.

    Is there any plans to offer different steel for the ice holder like DLC?

    Yes we have that kind of plans. Our steels need a different shape from what other brands have to fit our technology, but we have plans to have steels from different brands in the future. Unfortunately, I have no more concrete message than that to give at this point. 

    Best regards,

    Hello Petter,

    I am primarily an ice hockey player, who also plays inline hockey during the summer. After skating with the O1’s for about a month, I tried to switch to a HiLo inline skate to avoid the abuse that rougher asphalt runs the composite holders and wheels through.  I found that I could not skate easily in the HiLo’s any longer, so I went back to the O1’s for the game.  My concern now is, as I have pre-ordered the R1’s, will I have the same difficulties going back and forth with the R1’s and the O1’s as I do with the traditional (Mission) HiLo’s and O1’s, or will the R1’s and O1’s be similar enough that the adjustment will be minimal?  Also, for the medium chassis in both R1 & O1, what are end to end lengths with your standard wheel setups?



    Hi Rob,

    No you will not have that problem. Their is a clear diffrence between O1 and R1, and it is a clear difference between the different settings in R1, but they are all based upon the same technology so going back and forth between R1 and O1, or back and forth between R1/O1 and ice skates will not be a problem. 

    Stay safe,

    Hi Petter -  can you give us any info on what the required maintenance will be to keep the R1 in good shape and how easy it will be to perform eg what is required? Inline rinks accumulate a lot of dust and debris, how will this effect the rocker motion as the chassis gets dirty? Are you expecting owners to clean the chassis daily, weekly, monthly?

    Yes you are right that dust can end up between the upper part and the lower part which need to be cleaned out sometimes. It seems to vary a lot from rink to rink how much dust it emits, but according to our test players they have had to clean it out "once in a while", but that there has been no problem. An important note is that the dust has stuck to the insert that has been 3D printed so far during the development work, the final factory-produced insert will have a much smoother surface which will attract less dust.

    Except for that it should not be more maintenance than a regular chassis. Keeping the chassis reasonably clean, and putting new loctite on the wheel axles once in a while sounds good to me.

    Hello Petter! 
    do you know if True is going to offer the marsblade on their custom boots by any chance? Looking to try that combo out! 

    Hi Stewie, 
    I have no information at the moment if they have that kind of plans, I think the best way is to ask the question directly to True. The player who probably has the most test hours on the R1, John Schiavo, uses the R1 chassis with a custom True boot, and he really praises the combination.

    So, Marsblades...  I guess specifically the original O1's...

    Everything seems to say that they "feel like ice skates."  I'm trying to understand that a bit.

    I've never played roller hockey.  I do have a pair of inlines, but they're super cheap Vapors that don't fit that great.  They use a hilo chassis setup with 76 fronts and 80 backs.  When I skated with them, it felt like my feet were on skis or something.  Unless my foot was in the air, I couldn't rotate/turn my foot at all.

    I got some extra 72mm wheels and put them on to rocker the "contact patch" a bit and that helped some.  It felt a little more like skating on ice, where if your weight is over the balls of your feet, you can rotate your foot essentially without resistance.  But still not great.  Then I tried the extra 76 front in the back position, so that my wheels (front to back) were 72, 76, 80, 76.  That felt the most like being on ice.  But I noticed I didn't have much 'rear stability'.  It frequently felt like I was going to fall backwards if I didn't concentrate on keeping my weight on the balls of my feet.

    Which all brings me to my question about Marsblades... It seems like the point of the system is to let your foot rock back and forth longitudinally on top of the chassis...  But all four wheels are pressing down into the skating surface equally still, right?  So does your foot still feel locked in one direction when there's weight on it?

    I guess I'm wondering if the feel is different enough to what I have with my "regular' inline skates to be way more like ice skating.  With all the rinks shut down and my guess that they're either not coming back soon or that I won't be willing to be in them if there are two teams worth of people in there, I'm considering getting a little more serious about using inlines for off ice stuff.  Most of the reviews I see are from people that already do a lot of roller hockey.  I'm curious about the perspectives on this stuff from folks that have never really skated inline very much.


    I would claim that different wheel setups is barely comparable to the Flow Motion Technology that Marsblade uses. Flow Motion Technology is completely stepless while for example a 72, 76, 80, 76 wheel setups is based on jumping between three steps and always balancing on maximum two wheels at the time. I think this short film visualize it in a good way:

    When it comes to the feel of being locked in one direction you will notice a big difference with Flow Motion Technology. When you, for example, put the weight on the heel in a tight turn you will notice that the turning radius can be significantly reduced. However, of course, inlines have some limitation as they have another grip with the surface than a steel has with the ice.

    Question:  O1 Sizing

    Reference: I'm in a 7.5ee skate with 272 holder.   Seems I am in the middle of M/L.  I'd prefer to be on 280. 

    -Should I size up or down?


    Thanks in advance.

    Your boot will fit well with any of Medium or Large, so it is primarily a matter of personal preference. The Medium size weighs less, the Large size has larger wheels which is good for speed.

    I placed an order during the first round of the presale. Is there any way to track the status of the order, like to see if the expected date changes? Or will you guys send out emails with updates for any delays? Maybe I’m just missing it online. I know it’s still pretty far out, so just wasn’t sure how to check when it gets closer without bugging anyone for updates. Thanks!

    Not at the moment, but you will be updated when we know more about exact delivery. Unexpected delays will of course be announced, but given the precarious situation in the world, we have tried to take potential delays into account when estimating the delivery date. So of course we hope to be able to deliver faster rather than having delays.

    Hey Per, a few follow up questions if you don’t mind. all this talk about the R1 being for roller and the O1 being for off ice training, does the R1 replicate the feel of ice skates in the same way the O1 does or not? 

    Could you please provide more information about inserts and the effects they have on the rocker/skating? How easy are they to change? The short video on your site just shows it sliding in and out. Is it that simple? If it is, what keeps the insert secure in the chassis? 

    Lastly, are the lower part of the chassis anodized, painted, powder coated? I know blue is your color, but do you envision black or silver being offered in the future? Something more understated 

    Yes and no. R1 has much more of an ice like feel than a traditional inline chassis, but not as much as the O1. The difference is the rocker setting where the O1 rocker is design to mimic the ice hockey steel while the R1 rocker is designed for maximum performance. 

    The insert is attached to the upper part by a snap fit. It is easy to change but you need to remove the lower part (with one bolt) to reach it. The feeling of different inserts is of course a question of personal preferences, but by testing them ourselves and listen to the players who have tested them my impression is: 
    H5-T8: Most similar to ice hockey 
    H5-T15: A lot of heel movement but full contact during push offs
    H8-T8: Smoother feeling 
    H8-T15: Most controlled feeling, less movement i general but still clear benefits from the rocker

    The blue colour is anodized. Valid point, it's definitely a potential alternative, in the end it's a matter of how many players we see demands it.
