Hi all,

Shift lever on my Sram apex brifters has unexpectedly come off in my hand (stop it) - anyone think of a way that i'm not stuck in the 11t cog at the back until i get a new one sorted? (/stealth wanted ad)

Would I be able to adjust the limit screw enough to lift the chain up a cog or three or isn't there enough adjustment for that? I can't be arsed rigging up some Heath Robinson-esque contraption to hold cable tension & my knees aren't taking kindly to grinding around in 38/46 x 11

Cheers!

John

Surely it's not /that/ heath robinson to tie a knot in the cable by a cable stop and then tweak the barrel adjuster to leave it somewhere in the middle of the block?

I'd just push the derailleur by hand up to a suitable cog at the back, loosen the cable bolt, pull through enough cable to hold it firm and then retighten.  Use the barrel to trim it if it isn't dead on to avoid rub.

What theotherjonv said +1 as long as the cables held in the shifter.

If not take the cable out, thread it through as normal from the cable adjuster (if there is one on the frame or mech) then clamp it with the mech somewhere halfway up the cassette, twiddle the barrel to 'index' it.

New bike.

It's the only way to make sure.

An old bodge for if your gear cable snapped mid-ride (or if you were too lazy to fix something that happened weeks ago) was to get at least a couple of inches of the remaining cable, make a knot in one end and feed it through the adjuster end of the mech until it holds then clamp the other end as usual, after having selected a suitable cog.

Loop the remaining cable so it doesn't get caught and off you go.

Hi - have 2 stops on the seatstay that could work but they're slotted so i'd be paranoid it would slip & i'd tear my knackers off on the stem, can't see much else to hold the cable.

At least I have a new teaspoon.

Just use the limit screws, usually gets you a good few sprockets up the block.

Cheers all - if I don't get any joy with the limit screws i'll try tying a big knot in the cable at the derailleur itself, didn't think of that!

Will moving the high(low gear) screw allow more travel at the low(high gear) screw position, or am I mental?

New bike is the most obvious (and correct) suggestion but have a couple of nicer bikes just waiting for decent weather, this one is the winter beater - was going fine until some arse-piece knocked me off a few weeks ago, since then it's been one niggling thing after another - then the gear shifetr fell off...

Managed to get 2 cogs up using the limit screw - so now set in the 14t which should be fine with 38/46 for shortish journeys until I get a new shifter* sorted or grow some big ass legs.

*may or may not be attached to a new bike 😉
