As per title, do I need a chain retaining device on a 160mm travel bike?
And does it have to be a 22/36T double chainset?
i.e. does anyone run a triple or an xc double such as 27/39??
I have an xc double which I think I might put on a 160 travel bike but its a fairly beefy 160mm bike, so thinking it might not be the done thing or just plain out of place?
If anyone has photos of such 160mm bike with xc chainset on then fire away and post!
