Semi new to mountain biking after riding road for 35 years. After borrowing from friend his mountain bike for several years just purchased Scott Scale 710. It comes with XT 2 x11 with 11- 40 rear cassette. Thinking of switching to 1 x 11 with 10 x 42 cassette. To make the change do I just need a new 1x11 crankset using same BB ? Can I just swap the cassette to a 10 x 42 or will I need an adaptor XO drive ????

Easiest solution would be swap the rear cassette to an XT 11-46. A 10-42 (or 10-whatever) cassette would need a new freehub, like a SRAM XD or OneUp Minidriver.

if its got an 11-40 on the back leave it and just buy a narrowwide chainring to suit the crank. 32 or 34t

As said. Keep it simple. Just buy a narrow-wide ring for your crankset. Just match the bolt pattern.

To start just use the 11-40 cassette. If you find you need more low end climbing get the XT 11-46.

11-46 and 10-42 is practically the same spread of gears. Tailor what rollout you want that spread to cover with ring size.

Most people use 32 ring with 10-42 cassette. With 11-46 cassette a 34 ring is slightly easier gearing, a 36 ring is slightly harder gearing.

I think that bike has a XT 8000 crank and an XT 8000 cassette, My advice would be to buy a OneUP single chainring, and if you want a wider range than the 11-40, you can change that to an 11-45.

Agree with the above advice to just change the chainring for starters. Make sure to ride with the clutch engaged.

Never found you need the clutch with a narrow wide, not used one 3 1/2 years of just using an NW.

:noidea: Ive got XTR 1x11 with a 36 CarbonTi narrow wide direct mount ring, it drops all the time without the clutch.

But the OP can find what works for him :beerchug:

In OP's case I would stick with Shimano. Just get XT nw chainring and 11-46 cassette. Probably the cheapest and best option.

Have you checked if your CarbonTi chainring has the full narrow/wide pattern on the inside of the chainring? You can read about my issues with one of their rings here:
