i have an older mountain bike with brake bosses that are on the wider side, 90mm front and 85mm rear (or the other way around, i cant remember)
the rims i have on the bike are quite narrow, like 19mm i think.
obviously an option would be to rebuild the wheels with wider rims. but i'd rather solve the problem with brake choice.
i'm open to vbrake or canti. any suggestions of known brakes that have a particularly wide stance i guess? i have tried shimano v brakes, deore, and, with the wider spacer on the brake pad post towards the rim, they were still way too wide.
i've searched and read of people mostly having the opposite problem, narrow spaced bosses and how they made it all work together, but no specific models that work the other way.
also i havent been able to find any info from manufacturers about ideal brake boss spacing for their brakes, a range, etc.
i believe 80mm is relatively standard for modern frames.
