So, I have broken my second Raceface Next SL crank. I thought the first was from a pedal strike but ultimately after some digging the pedal boss comes unbonded from the carbon arm. Takeahikeshop warranties the first one in December. I just noticed the other side doing the same thing at CR on Thursday. After some reading it looks like it was a known problem and hopefully the G4 version has it fixed. I have the G4 on my fs bike. This really sucks when you have three bikes invested with them with direct drive absolute black chainrings and such. Big $. Are STAM XX1 cranks any better or am I looking at the same problem?
