My bike goes in for its 1st service on Wednesday. Reckon the lbs can do it, as it was part of the purchase after service. Yesterday, we went for a ride, and the gears started trying to slip. Of course, they'll attend this at the lbs. It's not that the gears did slip, but rather like the chain was trying to jump. It was all very frustrating and ruined a ride. And, maddeningly, it just started to happen. This got me thinking about cables. Sure, cables will stretch, but does this alone explain the sudden problem I got? What I'm aiming at, is that a cable that's new say, should still work when stretched, if all you have to do is to adjust and compensate for the longer length at the levers? Maybe I missed something in my irritation on the trail?
