I got a new chain fitted at a bike shop today but it is jumping when I get up to a decent pace/effort. I've got a week-long ride from Tokyo planned from Thursday and want to make sure that the bike is running smoothly by then. Am a lot of a noob when it comes to bike mechanics, so am wondering what i should do now... Options as follows:
- I'll go back to the shop tomorrow and get them to shorten the chain by one link
- I'll go to the shop where I bought the bike (at Y's, one of their Trek models) and get a new cassette, which should fit the new chain better. Are they likely to stock one that fits my bike since there is no time to order one?
- or something else?
The cassette was bought at the end of last year, and wasnt used from Dec to April, but maybe 700 or 800 km by now. The teeth on the sprockets don't seem sharp and still have a surface on the top of them.
The chain was jumping in any gear at any speed when I first rode it today, but then improved at some gears after a while... should the same happen for all the gears if I ride it a bit more.
