Ive been on a pair of cypres for 6 months. city streets mostly with glass all over the place. zero flats. 155lbs, about 55psi, and check for glass embedded in tire when I lube up the chain once a week.
the tires fucking rule. I wouldnt hesitate to run cerfs.

I had the same experience, and then had two flats and a sidewall tear in the last 1200km.
They ride great though, so I think it’s worth it, just swap out the rear when it’s getting thin.
[quote=blumpkin]have you used them?

Yep, I’ve been commuting and doing a bunch of other miles on 26mm cerfs for 2-3 years now (2x pr, just retired the second today). Australian city streets where there’s no bottle deposit system, so more broken glass. In that time I’ve had perhaps 7-8 flats, one was a 2" nail, one was a pinch on tram tracks, the rest small bits of glass. Couldn’t really be happier with them.
Have some parigi-roubaix to replace them, but will likely go straight back to cerfs afterwards.
rode 28c gatorskins @ D2R2 This year and they held up awesome! had put some commuting miles on them before hand and never had a problem. heavy and pita to mount though… thats not really a big deal i guess.
Got some in… they measured 25.5 so I sent them back. The ones mounted on Hed C2 rims at QBP saddle drive seemd wider though. Maybe a later batch was wider… maybe I’m crazy.
They aren’t true to width (on Open Sport rims they measure 29.5mm at 100psi) but if your bike can fit them they are definitely worth it. On my bicycle, and after ~900 miles of riding, they show some wear, but not excessively so (the meshy pattern on the blocks is worn mostly smooth along the road surface, but the blocks themselves are not worn. Maybe they’ll be good for 2500-3000 miles?)
