View Full Version : New help on changing crankset / Adams Morgan

Hi everybody,

I am young biker from France who just moved to DC.
I just bought a used mountain bike on CG but after a few rides, the right pedal fell. I took a look and the threads inside the right hand crank arm are totally stripped. :mad:

So I bought a new Shimano crankset on amazon but didnt succeed changing it. Anybody could give me a hand on that. That would be so helpful.

In the old days it used to be a little easier as there were fewer types of crank/bottom brackets to choose from but now it can depend on what style you have and this governs the tools you might need.

Unless you have the now more common external bearing bottom brackets like this:
where the cranks can be changed with an allen wrench, you'll need some special tools I'm afraid. I don't know how much you are willing to spend and how keen you are to keep fixing your bike over the coming years but it may not be worth it to buy the crank extractor tool that you'll need.

This would be a good time to get acquainted with your Local Bike Shop who can fix this for you.

Just a warning: New cranks means new chainrings (cogs on the cranks), which might not work with an already worn chain. A new chain and also new rear cassette (cogs on back wheel) might be needed too. Again another good reason to take it to the bike shop.

Good luck.

WABA (http://www.waba.org/resources/co-ops.php) lists four bike co-ops in the area that may be an alternative to a bike shop. I'm not real sure how any of these operate.

The bike house repair clinic on Saturdays at Qualia is very popular and has a good selection of tools on hand.
