That'll work. Or Paul's canti brakes. Or Avid Shorty Ultimates.

 

The bosses on some bikes are not permanently mounted but thread into fittings on the frame. It should be obvious because there will be flats on the shaft of the mount for wrench tightening. If that's the case, you can unthread the shaft and flip that disc around.

If not, you'll have to find out what specific brake was used on the Technium and try to source those.

If your 987's work without need for the spring mount disc, then I guess you solved your problem.

Agree, but there still is the shorter distance between the studs which could bring the brakes too close to the rim. Long shot, but can the springs in your Shimano brakes be reversed left-to-right?

 

Thank you for the suggestions. Thankfully the Dia Compe 987s worked just fine. The only issue is that the brake pad itself is a bit too long and rubs on the fork if allowed to completely retract. I ended up putting a spacer to make it work till I perhaps find a shorter pad.

The Shimano brakes that I purchased for it initially would not allow for reversing the spring.

Also, come to find out that even though the frame was sold to me as a road bike frame, it is in fact a mountain bike frame. I plan on a cyclocross type build on it.

Thanks for the info.

PS- In the photo it appears the cable is rubbing the tire; I assure it is not. It is just the angle of the picture.
