Somewhere out there i remember seeing a slow-mo video of tires rolling over the cobbles at Paris Roubaix. There was a lot of 'straight to the rim' impact happening. I think the tubular choice has more to do with avoiding flats and reducing rotational weight than anything. I ride FMB cx tubulars,

And man, the one way I could ride over that stuff is with a monster 4 tire bike . . . lol . .. but then I'd be riding so slow I'd just give it up and head to a pub . -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group. To unsubscribe from

Yeah, I had forgotten how tubulars allow lower pressures than equivalently sized clinchers. That explains, at least partially, why wider tires are not being used in the pro peloton. The extra weight of a fatter tire becomes a hindrance to the multiple accelerations a racer has to make so the

Stating the obvious , In the commercial world of racing bikes, if you want wider tires they call that a cross bike . Some teams use them too . And seeing there are only a handful of races for a select set of riders these would be considered there's no reason to make the racing frames take

Last year at Paris Roubaix, Quickstep were running 30mm dugast tubulars. There are occasionally guys who race cross bikes too. A 30mm slick seems like it would be a perfect tire for that race. It's absolute madness to me that some guys run 23/25s! On Monday, April 6, 2015 at 1:22:31 AM UTC-5,

Yes, they used a 30mm in the rear, but only a 28mm in front. I wonder if fork clearance prevented the use of a 30mm in front and, had there been sufficient clearance, they would have used a 30mm up front too. 23/25mm is indeed madness as is the lack of clearance on the race bikes that are

Wow, that's about a hair's width of clearance between the tire and the brake caliper. Tight doesn't begin to describe it! On Mon, Apr 6, 2015 at 11:18 AM, Paul G pauldowg...@gmail.com wrote: Yes, they used a 30mm in the rear, but only a 28mm in front. I wonder if fork clearance prevented the
