    140 or 160 mm rotors?

    I'm building a light-duty hardtail and have my eye on the Hope Mono Minis. I have the option of 140 or 160 mm rotors on the rear. How much weight is saved with the smaller diameter rotor, and what are the performance trade-offs? Thanks.

    Go Big

    I've got a dinner plate sized bruse on my butt because my mono mini's faded doing a high speed manual. If you're sure you'll never be into doing wheelies or manuals, and you're a true weight weenie, then go ahead and go small.

    Fade sooner since they heat up quicker. Weight is 89gms vs 115gms or so. I run 140s on 4 diff rears. No problems when run with Hayes, B4Pros and SLs, Avids. All raced ridden in NC(pisgah), N Ga, etc.

    If you go for the floating rotors, the weights are 90g for 160mm and 74g for the 140mm. Then there is a minor saving on the caliper.
