Hi all,
Got a Rob Roy that I'd like to put some wider tires on for the type of roads I ride on. Anybody put a 650B on one of these?

thanx, Pauly

Just how wide of tires do you want to use? RR's do not have a ton clearance with a 700x35 tire, but going to a 650b platform is not really going to make a huge difference other than making your braking setup a nightmare. A RR is a poor candidate for a monstercross setup soley cuz of the poor tire clearance. That being said I think it is the ultimate low cost gravel grinder bike.

well I stuck a 26" rim with 2.0 knobby and it would spin but the knobs were hitting, was thinking maybe 650b with a 1.75 might work, looking further though looks like my canti's might not work:madman:

You can try putting a long reach brake caliper on the bike. The tektro 556 has a ~70mm reach. You'd have to take some measurements and check out this page.
