Over the past couple of months ive noticed when im pedeling on the last 3 rings it jumps not from ring to ring. Ive replaced my rear mech for a new one but still the same could it be ive worn them out

I’d imagine so mate – that and your chain

How is the indexing of the gear?

Chain is pretty new shifting is ok

If i pop a pic on can u have a gander

This is the casette

Your photo doesn’t work and you can’t really tell through images

A new chain on a old cassette will always jump, unless it was swapped very early

The latest mud fest has played havoc with my drive trains – I needed a new chain ring on my 2×10 STX set up in less than 500 miles

Not a happy bunny

Ah stuff it ill invest in a new one any thoughts should i get another xt or less or maybe move to sram

I went with a used XTR for £15 and 2 new small cogs, lightweight and smooth shifting. the Big rings on XTR are unlikely to be the reason for the person selling the XTR 🙂 Plus you can buys individual cogs when required on XTR 🙂

Sticky cable
twisted frame
bent chain
stiff link
knacked mech
sticky shifter
bent teeth
bad indexing
and probably a few more things it could be. This time of year i would go for the last length of cable being cacked up. replace that bit, or a new cable set might work. cheaper than replacing chains cassette.

cassette looks ok tbh

All new cable brand new rear mech only 6 month old pc991 chain

you could have a sticky cable from new, but you seem to think thats ok so good luck

Silly thing it runs fine on the stand but when on the road and a bit of resistance there she goes

Worn cassette

Borrow a cassette and confirm if possible would be my preferred route

Sorry to butt in,but where did you get the small XTR sprockets from?
Rang Madison and they told me they are not bringing in XTR,XT or SLX sprockets.When there buggered new cassette! 🙁
Thanx,
Max

IIRC Rose Bikes did them but the site won’t load on my phone so can’t confirm.

I went ebay, but google bring up this…note its 9 speed

10 speed here

Rose bikes still have 10 speed…

Cassette looks worn. Compare the large sprocket with the smaller sprocket profiles.

Good call!
Thanx,
