Both chassis's will be damaged if they take a direct hit with a hard shot. We have several pairs of both the R1 and O1.
Marsblade has fantastic customer service.
We had a cracked lower on a pair of O1s and a cracked upper and lower on the R1s (all different skates at different times). Marsblade sent us replacement parts with expedited shipping to keep us skating.
We have had the R1s since they first came out and have seen significantly more action in competition and the O1s since 2017 or 2018
