[RBW] 650b Ram with Hetres, update 1
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).

tekro makes a slightly longer reach dual pivot sidepull. not sure of the part number but 800a rings a bell. ive used it and its decent especially if need the extra lenght and dont want to use centerpulls mike goldman warwick,r.i.

Toshi: if you don't mind a hack, try a small rattail file in the pad slots. I've added a couple of mm to old single pivot sidepulls that way. (Come to think of it, I added almost 5 mm to the short horizontals on my '99 Joe fixed that way.)

Hey Bruce, I still need to route new brake cables because the cables I have now are too short and swap the cassette because my RD is a road vs mountain on my other 650b rigs, but I plan a ride this weekend! Look for update 2 hopefully soon! If the test ride goes well, I'll file the hole 2mm. Thanks to all for the tips!

Re: [RBW] 650b Ram with Hetres, update 1
Toshi, 2 thoughts. First, Hiroshi at Jitensha years ago filed 1-2mm on a brake slot on one of my bikes. So I think that's fine. But, if you're unsure, some Mafacs had a vertical (oblong) slot instead of a circular mounting hole in the yoke, which would give you another 3-4mm. I have one of these on a 2000 brakeset i'm not using. If you want, I can measure the reach for you and see if it's long enough. Greg, also in Oakland, CA, but won't get a chance to get out this weekend.

Re: [RBW] 650b Ram with Hetres, update 1
Toshi, Another trick I have employed to extend the brake reach is to use mountain or v-brake style brake shoes/pads instead of road pads. The pivots on the mountain pads are thinner and the pads can sit lower on the slot--may just be enough to reach the rim.
