27mm wide and under 500 grams. Not sure if that is calling for a disaster or not. Anyone running them or had experience with them. A buddy of mine ran the 23 (or what is stock on a Kona Dee-Lux 29), they seemed to destroy easily. Hope that is not the case on the 27's...these would obviously be built hand built by a good dude around Hadley's....

Thanks.
