Bicycle falls apart while bicycling
#1
Hello!

My bicycle broke.

I mean that as in when I pedal the chain falls apart. It just happened on a routine bicycling trip when suddenly bang! Something went flying off the gears or something.

I know something is missing but I can't figure out what.

Thanks for any help you guys can provide.

Attached is a pic of the place I think is trouble.

Looks like the upper pulley of the rear derailleur is gone.

Cheapest: replace the rear derailleur; you will need a chain tool to break the chain, and put it back together, unless your chain has a master link.

This derailleur will work fine. http://www.amazon.com/Shimano-Tourney-TX55-Speed-Derailleur/dp/B003ZM9RDQ/

Actually you don't even need the chain tool. You can open the dérailleur at the pulleys. Take care to remember which one is going where.

You guys are awesome.

I'll get on this right away.

With spring weather already here, I'm missing out on a lot of bicycling!

Thanks!

just loosen the top pulley and remove the lower.Then swing the inner cage open and put the lower pulley back in while pushing the chain in with it
