i finally got the tufo tubular clincher low pressure cyclocross tires that i ordered for the build on the kogswell that i won. they're comfy as hell. i've been riding high pressure skinny slicks on NYC streets for so long i'd almost forgotten that there was another option.
if you have a beater with the clearance for 700X30 tires, i'd highly suggest checking these out. they're a bit pricey, but they seem well worth it. skipping on them stops the bike quite a bit more effectively than on slicks as well. i skidded them a few times just to see how it felt. it's good. it also stops the bike quickly, but i can't rationalize skidding on such pricey tires when skipping does the trick just fine.
mounting them isn't nearly as challenging as some have suggested in these forums.
the caveat with these tires is that they're low pressure, so they ride noticably slower than the stelvios or pro2race tires i usually ride. on a beater/bad weather bike, that's a benefit (to me at least), but you might think twice before putting them on anything you want to milk for speed on the street or keep 'em around on a second wheelset for crud.
