Hey everyone, new to the forum - found it while looking for info on my shifter which is misbehaving!
On the way home from a 70km ride yesterday, my bike started shifting up gears on its own. I realised after a while that if I hold the down shift lever in a little bit, it stops it from shifting up on its own. At first I thought the cable was slipping but I still had the full range of gears. When I use the up shift lever it doesn't "click" in to gears any more - the dérailleur moves and the gear changes, but there's no click, and after a few seconds it will start shifting up gears on its own again. I suspect something has gone bad with the ratchet mechanism but I don't know anywhere near enough to be confident here.
It's a 9 speed Veloce - unsure of exact age. Is this a common/known problem with an easy fix? Is it worth dismantling to attempt a repair or should I just find a second hand replacement?
Sorta new to this stuff so any and all advice is greatly appreciated.
Thanks in advance!
