I subscribe to Singletrack, rouleur and Cycling Plus.
Cycling Plus is great, all different kinds of bikes looked at, diet, fitness, etc. All the stuff that interests me and I read it cover to cover.
rouleur – an absolutely beautiful magazine, well written, fantastic photography, minimal ads.
Singletrack – it doesn’t really suit the sort of riding I’m into but its reasonably well sritten and designed.
