Derailleur won't shift into lowest gear

The bike shifts into every gear except for the easiest. I've adjusted the limit screws, but it didn't do any good. The Derailleur and shifter are shimano XT. I think the problem might be in the shifters but i'm not sure. How can i fix this?

If you've tried the high and low screws then try the cable tension barrel...if that doesnt work make sure the cable is tight(mayhave stretched a bit) if it isnt any of those then the indexing is off in your shifter

Well how do you fix the indexing then?

is i9t front or rear thats not shifting,and if its rear it could be your mech hanger out of whack.

if it aint i would try and reset the whole thing,but knowing how many gears you have would help also.

is that your bike in your profile,and if you have 9 gears then you should have 8 clicks from the shifter.

the same thing happened to me. your problem is the chain is too short, possibly just too short to reach around the largest gear in the back. well at least thats my problem. by the time my chain is trying to go into 1'st gear, the deraileur is useless because its stretched all the way out. you might want a new chain if thats the problem. or go ss

Take a 5mm allen tool and disconnect the cable.
Manually shift the derailleur into the highest gear.
If that works then turn the cable tensioner all the way in.
Reconnect the cable and tension it properly, using the tensioner for fine tuning.

If you can't manually shift the derailleur into that gear then you have problem with something being bent. Look it over and make sure nothing is out of line.

so if the shifter clicks 7 times then you just gotta readjust like the above post.

If you disconnect the cable, how do you manually shift it?

Move the mech with your hand.

I've got the problem that even with the limit screw all the way out to where it's not relevant, I still can't manually get the RD to be in line with the largest cog. Driving me nuts.

Thats not right Smile

Is your hanger bent? or your mech? ... is it possible that your B-screw is too far out, and its rolling your derailleur body too far?

So I'm not sure what I was doing wrong last week, but I got it set up fine tonight at least with the H & L limit screws. My consistent problem now though is with the barrel adjusters. I get the shifting working great between like the first 5 lowest gears, but then gears 6-11 are all out of sync. I mess with the barrel adjusters to get 6-11 working OK, but then all gets screwed up with 1-5.

Running XX1 RD, XX1 shifter, X01 cassette with OneUp 44T sprocket and XX1 chain.

Quite frustrating. I can literally build a bike from scratch and tear it all down and repair it, but for some reason I can never figure out how to tune a RD.
