turned my bike in last week for a tune up and a problem with the rear cassette. In the middle gears, mostly #5, when I get up out of the saddle it'll jump teeth. Sometimes one sometimes from a crank 1 and 7 o'clock postition 180 degrees. KRRRRRRR-CHUNK!!!
Took it to the shop, splained the situation and said it could be rear cassette. They tuned it and said it was fine. Took it out and same thing but only in #5 and happens in a 3 chain rings. Took a hard close look and some of the teeth look out of whack. Some bent in a bit more to either side. I'm guessing they didn't catch that since this is a "free" tune as part of their lifetime service if you buy the bike there. I had replaced the chain when it first started doing this and it didn't help. Front crankset is about a year old but the bike is 4.5 years. Derailures and cassette are the original Shimano LX's.
Anyone? thanks. I'm a newbie
