Will a Race Face 'single' chainring be compatible with a sunrace cassette, taking into account both are designed for 10 speed 1x set-up? Can I use the same chainring securing bolts as I currently have; being: Shimano SLX 2x set-up?

Thanks, Cameron

    Since the bolts are meant to keep to rings in place they will leave a gap when fitted with a single ring. You can either get shorter single ring bolts or put washers if no such bolts are available for your cranks.

  • @Carel This is a different question than singlespeeding a road double or mountain triple. The OP's crank has a set of bolts for each ring. They're installing a narrow-wide ring with a thick section at the bolt holes and they're presumably asking whether the bolts they've got will be long enough for it. Sep 5, 2016 at 21:34
  • Thanks fellas, after a bit of research I found that the Race Face ring bolts must be 8.5 mm of thread. Luckily, the outer ring bolts from the shimano are actually 8.5 mm. So, when my new ring arrives, I expect it to work??? :-D Sep 6, 2016 at 16:20

  1. As long as you have a ten speed chain it should be fine.
  2. Presuming this is FC-M675 or FC-M677, use the 8.5mm bolts from the inner ring. The 7mm ones from the outer are below Race Face's recommended bolt length.
