The new SRAM NX crankset for MTBs is available in 155mm crank lengths, which ideal for running on youth bikes. At the moment my son runs 155 cranks on a square taper BB, which is pretty heavy and not serviceable (using a UN55 cartridge).

i was thinking these SRAM NX cranks might be interesting for him, especially as he runs a single ring at the front.

But what about chainline? Being MTB cranks they will have a wider Q faster won't they?
