My LBS says it's time for a new chain and cassette after 2,000+ miles on my 2005 Cannondale R700. Being still somewhat of a newbie I have some questions about replacing them.
The bike came with a SRAM 950, 9-speed, 12-26 cassette and Shimano CN-HG53 chain. I didn't realize there was such a mix with a bike that has a Shimano 105 front derailleur and Ultegra rear. Is that common?
Any recommendations on replacing the cassette and chain?
