• Not track specific, but sure it'll be alright:

    Its a ten speed though, so 3/32. There are plenty of single chainrings for MTBs, but mainly for those runnings a single ring upfront and a cassette on the back, like for 4X or Freeride/Downhill, there seem to be few single-speed specific rings in the wider width, and when they are they are often discs for use with 3pc cranks. Very frustrating: I may just have to swap around the rear sprocket and go for a bigger front ring
