I have a Scott Scale 710 with the m8000 xt crankset – 2×11 – with 26/36t setup. I feel quite undergeared.

Question. Can i use the 28/38 chainrings on the 26/36 crankset? I found a website which separates then into BA/BB/BC and BD.

Has any one done this? Can it be done? Do i need a new crankset?
I tried to find the 28/38 chainrings but havent had much luck 🙁

Cheers!

Yes.

As it happens, I’ve got a pair of XTR M9000/9020 38T/28T rings – unused, and still in packaging, but they use a smaller chainring bolt size unfortunately.

Typical, so looks like i cant use the XTR rings then if different bolt sizes. Nothing is ever easy.
My search continues for the chainring pair in XT then.

I’ve run the 40-26 front rings with no problems and perfect shifting, and an 11-40 on the rear giving me big range.

There isn’t a 40T chainring for those cranks – at least not by Shimano

Ha! Cheers Scotroutes. Never thought of searching in german, but thats great. Id tried the usual suspects, CRC, Wiggle, Merlin etc…
Its my first 2×11, and had first rideout today on it. For the ride i did, i was always close to the top and missing my triple chainset bikes.
a 26/40 sounds an ideal setup. Already got a 11-40 on the rear as standard setup on the Scale.

How worn are the 36/26?

29.9km done on the 36, 26 never used! 😀
the bike is 2 weeks old, first ride today after weight weenying and making it tubeless.

PM me a price if you’re looking to sell them then 🙂

Got a pair of brand new XT 38T 26T chain rings. Got a cheap deal on an XT crank that I just wanted for the arms so never used the rings. They’re 10 speed rings, but will work fine for 11spd as the internal width of 10 & 11spd chains are the same, it’s just that 11spd chains are 0.3mm narrower externally – front mechs aren’t that precise!

EDIT: ignore me, forgot the 11spd XT is a different BCD!

That’s parts diagram for the m8000 the part numbers should help you find the rings you want
