This is on an older Specialized Sirrus, of unknown year using Suntour derailers. I cleaned and
lubricated the cable guide on the bottom bracket, according to suggestions on Sheldon Brown's page.
I also adjusted the rear derailer according to his guidlines, and tightened up the shift lever
(which helped briefly though it quickly loosens after use). I noticed the rear wheel seems loose on
its bearings... I can easily wobble it by hand. Would this contribute to upshifting during hard
pedaling? Someone at a bike shop said it could be that the gears are worn out. Not expecting more
than $100 in selling this bike, would it be cost effective to replace any parts causing this
problem? To this end, could someone recommend any reading so I can make the appropriate choices on
replacement parts? Thanks, Derek
