Interloc Racing IRD Switchback Cantilever Brakeset w/ Tubular Booster & Straddle Cables: Black - 1st Gen Not Drilled - Linear Pull Setup (Near Mint)

Rare early version of the Interloc Switchback brake.  It was introduced in 1989, and somewhere in the early 1990's they added three holes to each arm. This is  a full front and rear setup with straddle cables/carriers plus an ultra obscure tubular brake booster for the front.

Description of the brake with it's pulley setup: "This is a cleanly machined cantilever brake made largely of aluminum with a few steel pieces. It's a powerful brake with a soft feel, excellent for front or rear use. The Switchback uses a unique cable routing to pull the arms together, which eases strain on the mounting studs and eliminates the need for a "booster plate" because the power is already boosted by the concentric wheel design. This brake uses an extra long straddle wire that is wrapped around an aluminum wheel at the cantilever arm end. The wheel is fastened off center so the rotation of the wheel when pulled, is concentric.  Because of this powerful cam principle, a small, tiny, little brake lever pull becomes huge rim clamping power."

Condition

Near mint lightly used shape.  Pretty minimal wear.  Anodizing on the arms show hardly a mark, mostly just a few spots on the sharp edges. One brake isn't faded at all, the other is slightly faded (but you'll only notice if they're sitting next to each other).  One brake has NOS period Dia-Compe pads & the other has Madison pads at ~90% or better life left. Hardware is near mint or better with only light wrench marks on the tension nuts. Slight ano wear on the cable carriers. The mounting bolts are mismatched.
