I do like the look of the brake's. I don't know much about Ross Bikes. If I were for sure selling it, I would probably keep the brakes to use for my self and sell the bike. If you look at e-bay prices, the prices are all over the place for just the brakes, from just giving them away up to some pretty decent prices.
I might have to keep a look out for those, I think they are cool.
Yep, these are called Roller cam brakes. They were designed by Charlie Cunningham who sold the design to Suntour. Charlie was an early mountain bike inventor. I had these brakes on my 1985? Schwinn High Sierra.
