There doesn’t seem to be many options for running a direct mount single chainring on a traditional external BB with 24mm spindle. So far, I’m liking Race Face’s AEffect. What others are worth a look?

SRAM… Anything with removeable spider. I’ve got XX1. But think X0 are the same cranks.

Wow, that was a quick response for a Sunday morning on here! I’m a bit blind to SRAM, having run Shimano for years. What models for 10-speed, budget of up to £100 for crank arms only?

None of them. But you didn’t specify that in your OP!

FWIW the 10 speed is an irrelevance, but <£100 is very limiting.

Just get Aeffect, they are brilliant.

SRAM need a GX BB… you can convert a hope but just about amy other Shimano compatible BB won’t work.

Using Aeffect myself, delighted with them
