From what I understand with this Race Face chain ring you don’t need a guide.
Right, but in conjunction with a clutch rear derailleur. I don’t own any of this single ring stuff, but I think the idea is that as you have it you may drop your chain on some serious bumps, whereas with the derailleur too you’d be fine. But if I were you I’d say having to put chain back on once every 75 miles isn’t that big of a deal!!
