Tri Diameter

[kpeach122 0]

I currently have CCm skates. I saw some people saying that they dont like the tri dia chassis. What exactly is that?

It uses 3 wheel sizes, 72-76-76-80. Hence the name tri-di(ameter). Mission currently uses a 76-76-80-80 setup and Tour uses straight 80's on their higher level skates.

the CCM's i have now also came with 72 76 76 80, so its the same thing. Any other reviews or comments on the 7ks?

Some people don't like the rockered feel the three different wheel sizes give, but I think most people who don't like them (including me) think they're a pretty flimsy chassis -- there's not enough internal bracing to the frame so if you over-tighten the axles, you'll make the bearings bind up. Unless you're judicious about using threadlocker on the axle bolts, you'll find it hard to keep them tight without binding. I hated the Tri-Di on my RBK 8ks, I'm glad to be back on a Mission chassis.

what do you mean by a flimsy chassis?

On something like a Mission Vanguard, there's a fair amount of internal bracing so you can tighten the axle bolts without causing the chassis frame to flex and make the bearings bind. On a RBK/CCM Tri-Di, you don't have that kind of bracing and you run into issues like I described above.

I was intrested in getting a pair of new rbk skates whe n they come out

but now im kinda not after reading this. Should i just stick with tour? with the 80-80-80-80 hummer chassie i have felt like ive gotten faster. if you switched to a tri-die would i be slower?

The bigger the wheels, the faster you'll go with less effort. But the trade off is a larger turning radius, so with the smaller wheels you'll have to skate slightly harder to get the same speed, but will be able to turn slightly easier.

On my old skates I had aluminum Tri-Di chassis and I recently switched to Magnesium Vanguards. I never noticed a problem with the Tri-Di's until I switched to a better frame, then I realized they are complete shit. I'm probably a Vanguard for life guy now. And I'd take the Humm'r frame over Tri-Di's any day. Stick with tour, or buy the RBK's and put your Tour frame on them. Any decent hockey shop will do it.

part of that is true. 80's are faster but take little longer to get u to speed but stay at speed longer. tri-di and vanguards have more agility and take less to get up to speed but do not go as fast or stay at speed as well as straight 80's
