I have a road bike with an Ultegra 9 speed groupo. It has about 2000 km on it. I recently took it in to a lbs for a tuneup as it was not shifting crisply.
The owner took out a Park chain tool and told me it measure ".75" and the chain needed to be replaced. I expected as much.
But then I was informed the cassette need to be replaced as well. That didn't seem right to me. I asked for the chain to be replaced but decided to delay the replacement of the cassette.
I clean the chain and lube it religiously. I'm shocked the cassette could need replacement. Has anyone worn out an Ultegra 9 speed cassettes that quick?
