any help would be great,messed about for too long now,

tried tension and limit screws,the usual lark,clearance over big ring.

the mech wont even shift back down onto the granny ring now and thats with the cable slackened totally,likes its siezed or something,but it cant be.
its an SLX triple chainring front mech,worked perfect before i took it off other frame to put on the one its on now.
any ideas?

is it hitting the frame? i know that sounds silly but sometimes if your chain line has changed the front mech will need to be in a different place. iv seen it a few times in the shop. what crank set is it?

sometimes over tightening the limit screws causes it to not go to the opposite extreme. Due to the shape of the cam they touch. Try loosening both off 3 or 4 turns but remember where you had them.

hmm crankset is SLX too.my chainline is different on this frame ive put mech on,which ive corrected,
done the limit screws both ways no sucsess.mech still stuck.

had enough tonight,gonna attack it again in morning,and look on here.

cheers.

are you setting the mech limiters up with the cable attached? try taking the cable off and adjusting the limiters.

good luck

Does it move ok without the cable attached? if so maybe a kink somewhere

no it doesnt move without the cable attached,chain on big ring,drop chain onto small ring with my hands and it jumps back up onto big ring, thats with no cable attached.

can you post a picture? have you moved the mech as far in as possible?

Inner plate catching on middle ring??

Is it upside down 😆

Broke in my book unless there's a limit screw jammed all the way in?

was siezed up to buggery!!! and its quite new,freed it up and now working spot on 🙂

oops dirty mech.
