Fairly unobservant - 15:26
When I broke my collar bone in April, the road bike (well cyclocross bike) I was riding that day suffered some damage also. The front wheel was scalloped and broken in many places. The Saddle was broken and there was a nasty case of road rash on the STI shifters, everything else appeared fine however.

When I first started riding the road bike again, around 5 weeks after the accident, I thought at the time the right pedal was somehow rotating strangely or off in some way. However I put it down to getting back on the road bike with my collar bone in a state and ignored it. I also obviously got used to the sensation while ignoring it.

A few weeks ago I was doing some commutes on the cross bike with chunky tyres and was using 2 bottles in the cages often. Watching my legs rotate I noticed the right leg was hitting the frame and bottle a bit and yet the left leg was a huge distance out from the frame and anything else. Intrigued I then analysed my riding on some of my other bikes, I happily found the other bikes did not show off this trait also thus I was fairly sure my entire body had not somehow become unbalanced toward one side on the bike.

This did however mean something was obviously wrong with the cyclocross bike. Today I finally bothered taking it in to the bike shop and they measured some stuff, at first they were also flummoxed, until someone thought to measure the distance of the cranks from the frame. It turns out I bent my right crank inwards by 11mm in the crash, it was not hitting the frame and is not obvious unless you know to look at it for it being bent in compared with the other crank.

So I sort of suspected all along something was wrong, however made myself ignore it and get used to it. I am probably fairly lucky I have not been doing much riding this year so I have not changed my pedalling or muscle action or anything to accommodate the problem with the bike. Now I really do have to seriously consider buying a new groupset for this bike with a triple on it in order to enable it to climb in mountainous country more easily.
