I mounted the Hetre tires on Synergy 650b wheels and swapped out the calipers to Tektro R559. In the front there is gobs of room--over a cm on all sides. In the back there is sufficient room with plenty of room up top, and the minimum clearance is in the chainstays with about 4 mm at minimum on each side. There should be plenty of room for fenders, as Jay described, which is great.
The bad news is that the R559 caliper on the rear right side does not have enough reach. Maybe 1 or 2 mm would do it. In order to take a test ride, I'm flipping the brake pad in the "reverse" direction. I don't know how much of a difference the pad will make if it's upside down, but in that configuration the brake won't hit the tire. The Tektro brakes have 73 mm reach, and in theory, there are 75 mm reach brakes, which should hopefully work. I've kind of searched around the web and found some IRD B75 calipers, but they only seem to be available in black right now for the rear. I prefer silver, but... I also saw some DiaCompe centerpulls. I've never used centerpulls, but I could switch to those, since they also claim to have 75mm reach. I would appreciate any experience with the centerpull brakes in contrast to the dual-pivot calipers. If there are other 75 mm reach brakes I should consider, then it would be much appreciated too (I see BMX-style brakes, but have no idea about how they would work on a road bike).
