Jim, Living in sunny southern California, I've never had much need to fender my Romulus -- and hence never have. According to Riv's Romulus catalog specs, it is supposed to be able to take a 32 mm tire with fenders or 35 without, so I'm confident my Romulus could fit fenders and the Challenge tires. It also uses the standard reach brakes. My understanding of the old Road Standard that you have is that it uses short reach brakes. Right? If so, it probably tighter clearance than the Romulus.
I don't own a micrometer, so I can't comment with any accuracy on the width, but I seem to recall measuring the height once at about 28-29 mm from the top of the rim to the top of the tread. They're definitely plumper than their 27 mm label and I'd be inclined to agree with others who say they're more like 28-30 wide. >From what I remember of the Pasela non-TG in 28 (which I briefly tried before the Challenge), the Challenge are roughly the same width and height on my Mavic Open Pro, if that gives you anything to grab onto for comparison's sake. (But the Challenge are a much nicer tire!) I hope this helps. Aaron On Dec 3, 5:01 pm, Jim Cloud <cloud...@aol.com> wrote: > Aaron, > Just curious, does your Romulus have fenders?
