Best way to shorten straddle cable for Dia-Compe 980s?
I have a couple early to mid-80's bikes with Dia-Compe cantilever brakes, which take double-ended straddle cables. All the manufactured double-ended straddle cables I have found are too long (330mm) for my preference, and I would like to lower the yoke height by about 50mm. What is your suggested or preferred method for accomplishing this? Is there a pre-made adjuster bolt that could fit these brakes in place of one of the normal ends of the straddle wire? All the ones I've found are for brakes with wider spaces on the arms, like VO's Grand Cru Cantilevers, or the Jagwires. I have one bike with Dia-Compe 981's, which have an adjustment mechanism on one arm, so they only need a single-ended straddle cable, and these are pretty nice. Is my only alternative to replace the brakes?
