So i have this about 2011 XT triple cranks, i want to turn them into 1 x 12
so :
Hello !
Which bolts do i need ?
Which brand should i buy? (would be nice if i can get from bike24
And which gearing should i get?
- riding mostly flatter technical single trails, some smaller steep climbs...
I think the BCD is 104
The frame is a carbon pivot mach 6 .. i think the xt cranks should fit ...

You just need a 104 BCD Narrow/Wide chainring. I'd go for an Absolute Black oval.
How many teeth depends on what cassette you're paring it with, 10-50 then 32 should be fine but you could also go for a 30 if you have some super steep climbs.

You wont get a 104 BCD ring as small as 28. I think the smallest is 30 for round and 32 for oval.
You will also need some shorter chain ring bolts. Bike 24 has Problem Solver chainring bolts that will work
Won't work as frame is boost, and those cranks are most definitely not. New cranks I'm afraid!
check it first. I run non-boost cranks on a boost frame. As long as the ring clears the chainstay then it's fine.
+1 on going oval. As said, a 32t is the smallest on a 104BCD. See Work Components for cheap, decent rings. AB are pricier.

I'm running non boost cranks with a Boost 32 oval chainring on a Boost frame with no issues.
You can get 30T oval chainrings for 104BCD from Absolute Black as I’ve got one. It uses thinner bolts for the short radius so the chain doesn’t foul the crank arms.
Dunno about the boost part, suspect you’ll just have to try.
Use one of the gear calculator sites to work out what cassette you need.
