I recently bought an old (and cheap) road bike and I quickly noticed that the bike's crank set is "broken" because it had a weird bump when pedalling.
I took apart the crankset, and noticed that the wedge connecting one pedal to the crank as well as the crank itself is pretty worn down. I switched out the wedge and filed down the worn down part of the crank so it is flat again. I also added a shim of metal in between to make up the filed down part.
This fixed the problem for some time but now it is back, so I think it is time to replace the crankset or find a more long term fix for the problem.
I want to replace the crank set for something with a more durable attachment mechanism.
I have never tried doing this myself but I looked around a little to find out what I even have to keep in mind when look for a new crank. The measurements of the current crank are the following:
- Housing width is 70mm
- Housing diameter is 40mm
- Bearing cage 34mm
I started look for parts but I really don't know how to find them and what I should look for and this is what I was hoping y'all could help me. So basically I need a shopping list. :D
