During my ride today it felt like my pedal 'chain side' hit something hard and and broke, although there was no rocks or anything about. Turns out the internals of the pedal gave up, which isn't really a problem as I have been using some older spd m505's just while I get used to spds and was planning an upgrade very soon anyway.
However when I took the pedals off the one on the other side was very very tight and now it seems the thread is rounded as no pedals will screw in, I've only lightly tried as dont want to make things worse.
The problem is I've got a new set of deore cranks on there and I will not be pleased if I need new cranks again. They were fitted by my local bike shop. Would them being over tightened of caused any damage?
Do you guys think there definetly rounded from my probably quite confusing post. I was going to order some deore xt's online and fit them myself, but would it be wise to buy through the shop and ask them to fit so matters are not made worse.
If it is definetly rounded is that game over for the cranks?
Sorry for the long and waffled post but any advice would be greatly appreciated.
Ps forgot to mention the last crank arm was also rounded when I got the bike hence why I bought new ones, could the pedals be causing some upset? Although the bike shop seemed to fit them on ok
