Why can't I get my gears shifting properly?
On my crosser/roadie, just changed the cassette and chain as the shifting was awful and they were slipping, well they had done six months commuting through the wettest winter ever, anyway new c&c and shifting still crap, so I replaced the mech hanger as I did have an off a few weeks back and landed drive side down, still no good. Cables all good and not fouling, mechs okay (tried a spare as well).
Every time I shift gear to go up the cassette it requires a good 2-3 turns of the barrel adjuster to change gear, almost as if the shifter isn’t taking enough cable.
Anyone got any useful tips or is it new shifter time? The ones I’ve got are about 5 years old and have done several thousand miles and are Tiagra 9 speed.
Thanks in advance.Posted 3 years agopdwMember
So you put 2-3 turns on the barrel adjuster, then what? Will it shift up to the next gear? Will it shift down again?
If you find that it continuously needs more and more tension, the cable may be breaking strand by strand inside the shifter.
Otherwise, change the outers. Modern shifters like a nice long loop of outer to the rear mech.Posted 3 years ago
pdw – yeah pretty much needs 2-3 turns of the barrel adjuster each time to get a shift, then there is so much additional tension on the cable that you the chain won’t return to the smallest sprocket.
Going to try new outers and inners tomorrow, it always used to work fine, so I’m assuming the set up is fine.Posted 3 years agoTiRedMember
It will be friction in the final cable before the RD. Replace and all will be well. One of the most frustrating niggles to diagnose, but easily sorted.
That cable outer can look fine, but the ferules kink easily and cause tension. Nothin to do with the barrel adjusters.Posted 3 years ago
