upgrading an old drivetrain
New member here - Greetings all.
I have a great old '97 Kestrel with the original Shimano 600 2x8 groupset. Naturally, it's getting quite worn. I've been advised that my replacement choices are either go find OEM 600 components (which are terribly expensive - espceially for older technology), or upgrade to an entirely new groupo (which I wouldn't mind doing).
However, if I go with an upgraded groupo, I am limited because of width issues on the rear wheel for a new cassette. Otherwise, I will also have to replace my wheels (which I don't want to do). Specifically, I've been told that I cannot go to any of the newer 11 speed sets (which isn't necessary for my budget & riding goals). If this is correct, then I still have some attractive options, such as going with a Shimano 105 2x10 groupo.
My concern is that it really is compatable before I buy a new set and find out it's not a compatable upgrade for whatever reason(s). I'd greatly appreciate any advise/experience on this matter. Thanks!
