[RBW] Re: Weight weenie report. Dia Compe 980 brakes

Just saw this as I am in search of canti brakes without having to break the bank with the likes of Paul's or Velo Orange (as nice as they are...). I notices the 980's and am wondering what your experience has been with these. On Wednesday, August 22, 2018 at 1:38:49 PM UTC-4, Bill

My 1991 RB-T bike was stolen a couple years and I found a 1994 RB-T to replace it. Cantilever post widths are significantly different. I can fit a number of brakes to my 1994 fork that would not fit my 1991 fork. Dave in Kansas -- You received this message because you are subscribed to the

Max, Apparently my reply may have been misread as I pointed to the *CR710* *for narrow spacing(they are designed for cross bikes with 33mm+/- tires)*, not the 720. The 710 costs about $20-25 each.

[RBW] Re: Weight weenie report. Dia Compe 980 brakes

Got a pair in. So far it's been a breeze to set up, but I ditched the straddle hanger for moon units. The spring tension seems pretty even out the box. Did not have to adjust spring tension at all so far. So in that sense, it was just slightly easier to set up than the Paul Neo Retros. Can

[RBW] Re: Weight weenie report. Dia Compe 980 brakes

Garth, I agree that the 720 is a good brake and a good value. In fact I have it installed on one bike, but had to move all of the spacers / washers to the outboard side of the pad holder bolt, because the canti posts are closer to each other than currently standard. It actually works fine,

[RBW] Re: Weight weenie report. Dia Compe 980 brakes

FYI these work better than other brakes I've had, but perhaps it's the lever. I have not put KoolStop pads on the Dia Compe 980 yet. Any suggestions for which? I am thinking just the Supra, same as I have on some V-brakes unless there is a better type to use on V-brakes and I'll swap -- You

[RBW] Re: Weight weenie report. Dia Compe 980 brakes

Max, Any cantilever intended for a cyclocross frame is by nature for narrow spacing. You might try a Tektro CR 710 for example. These are easy on the pocketbook AND work well. I replace all Tektro pads with Kool Stop blacks or salmons even before installing. I have this brake on my Bomba

[RBW] Re: Weight weenie report. Dia Compe 980 brakes

It depends somewhat on rim width, but I think around 80-85 is generally what most v-brake/canti posts are set at these days? Builders will know, but I believe I read 80mm suggested on a framebuilding forum (Curt Goodrich?). That's what I used for my spacing when I redid some posts for a

[RBW] Re: Weight weenie report. Dia Compe 980 brakes

I'll be curious to hear how they compare with Tektro CR-720s. I'm reasonably happy with mine, but the Diacompes are certainly prettier and also shave off a bit of weight. And people have complained that the Tektro has too much flex/play. Harald in Madison (WI) On Wednesday, August 22, 2018

[RBW] Re: Weight weenie report. Dia Compe 980 brakes

The difference between 622 and 630 is 8mm in diameter and 4mm in radius. The 622 pad will be 4 mm (1/6 inch) closer to the canti post than the 630. If it is within the range of the standard slot for pad mounting, it is not a problem - every pad slot on a brake arm that I have seen was

[RBW] Re: Weight weenie report. Dia Compe 980 brakes

Compass brakes are $300 for two wheels. Dia Compe 980s are $52 for two wheels. The price difference is $248. If the weight difference is 7g per wheel, then that would make that $17.71 per gram. When I'm going weight weenie, I'm looking for $1/gram opportunities. If I can throw $450 at my

[RBW] Re: Weight weenie report. Dia Compe 980 brakes

Paul Please don't misunderstand me. I specifically referred to converting from 27" to 700c on cantilever equipped frames. If the cantilever posts are in the right place for 630mm rims, you have to run the pads quite low for 622mm rims and the mechanical advantage gets all messed up, forcing

I have no specific thoughts about the 980 suitability for a 630 to 622 conversion. My general thoughts are that 630 to 622 conversions with cantilever brakes are always massively compromised, and I'd personally never bother with such a project. If I was helping a friend who was dead-set on
