180mm vs 160mm rotors

J.B. Your equations are a bit higher grade for me but I get exactly what you are saying. It boils down to like for like, the same make rotors with the same brakes and pads you will always get better performance out the larger rotar. Just look at Ferraris etc. The faster the car the larger the discs.Also of course if you have ceramic pads you will even get better performance as they build up much less heat. The XX is 160 front and 140 rear as it is geared towards the race snakes where any amount of weight saved is better plus these riders are almost always better technical riders and thus use far less of their brakes when negotiating downhills.Lastly from the write ups I've read about the Xx it seems the new taper bore technology and pistons etc makes these brakes far superior to the Juicy ultimates of the past and yet they are much lighter.

180 looks better, and works better especially on a FS. Nuff reason 4 me. mm, said that the wrong way round. It looks better on a FS and works better regardlessBos2010-01-19 02:52:03

I ride with a 180 disc up front in hope that the bigger lever arm gives more braking power and the larger surface area helps to cool it quicker.
