"Some of you will want to throw 650b x 47c’s in it, that’s cool. The resulting slightly lower BB gives the bike excellent manners when riding with a load and is fully endorsed by us. If you want to run a 700c tire the max is a 42mm tire which will raise your BB by 8mm. 700c x 38 keeps the BB about the same"
