Hello all
So this has happened twice to me now, same crankset, different sides. SRAM Red 22 10 speed, using Shimano 105 pedals (all I had at the time, never bothered to get better ones)
Originally in DEC 2014, 4 weeks after getting this road bike, I stood up to put power down in order to chase a friend up a small incline and the right pedal pedal sheared out of the crank. I rode the bike to the ground, getting concussion and breaking my thumb on left hand. I put this down to probably my fault, the pedal must not have been in properly, or tightened properly. Although there was the threads from the crank still around the pedal thread - little washers of broken metal. I had ridden the bike perhaps 20 times in that 4 weeks, each ride between 30 and 100km.
Replaced the one crank arm, but from that ride onward, have religiously checked my bikes pre-ride. Road, TT or MTB - regardless. Somewhat paranoid - the broken thumb took me off riding for 4 months.
Fast forward to yesterday - was behind a bus at an intersection, so stood up to put power down and try to get some draft off the bus... Left Hand side pedal sheared out... almost identical to the first time. Thankfully my foot hit the ground (pedal still attached to my shoe) and I was able to stay on the bike. Pedal had metallic rings around it, thread mostly gone from inside the crank arm. I had checked pedals prior to riding and both were tight.
Have contacted SRAM for a "please explain" but as yet, no response.
Has anyone else had a failure like this across any group set?
All my other bikes (TT, 2 MTB, wifes MTB, kids MTB's) have shimano and its been rock solid despite my abuse. So... likely going that route with replacement...
