Fancy trying a 40t outer on my triple chainset, anybody know where I can get one. All the ones I can find tend to be without shift pins and ramps.
It's for a XT770 crankset 104BCD. Is it an unusual size, the smallest pinned and ramped ones seem to be 42?
More importantly do the pins and ramps make a big difference? I have only ever run ramped and pinned ones so I don't have a clue what amount of difference having them makes.

try a middleburn slick shift. think they do them in a 104pcd 40t.
just out of interest why do you want to run a 40t?
tried middleburn and they only do 42.
Running a 44 at the moment and tend to be either at the top end of the block on the 44 or at the bottom end on my 32 middle. (which it tends to drop the chain a bit)
Just thought a 40 would give me a decent chain tension to try and stop dropping the chain and not be on the big ring at the front and the big at the rear.
Maybe a 42 will suffice?
probably need to look at the ratios which I have not done yet 😳
i use a ta chinook 40t middle ring in the big ring position on an xt triple chainset. from sjscycles about £40

Keavo does the 40T fit okay with standard bolts as much like Vortex i'd be keen to try a smaller big ring.
the ta 40t middle fits o.k. but its not quite perfect. the ring is a little loose where it bolts on to the crank spider. once the bolts are in and tightened its o.k. it shouldn't move....mine hasn't anyway. also the front mech needs to stay at about the same height as if you had a 44t on, if you move it down it will catch the 32t ring.
The 32 - 40 won't be a very good shift, would recommend just doing a 2x9 set up and going for 26/40 or something.
32 to 40 is a great shift, fast and quiet.
Double and bash!!!!.
36 outer means ya only drop the 44 x 11 & the 44 x 12 or 13. Tho you know this as I ramble on about it every week 😉
We'll work on getting rid of that granny ring laters 🙂
40t is good on 29er, 44t is too big even on a race bike. i've tried 2x9 but concluded that if i'm going to have a mech and shifter i might as well have 3 rings. a 30t middle would be better too.
DMR make (well, more likely import form tiawan) them IIRC, they certaily doa 38t which i'm considdering, the 36t steel shimano one is doing the job nicely at the moment though.
