Hello all! I am looking for some information from anyone out there that has any feedback to share regarding the use of mechanical disc brakes front and rear. First,let me describe the set-up I intend to use. The tandem is a Cannondale MT 800. The fork is a "Fatty R". The wheels are 26" Velocity "Aeroheat" rims mated to DT Swiss 540 hubs. The spokes are DT Swiss alpine III (tied and sottered). The brakes are Interloc "dual bangers" (otherwise known as "WinZip" from Santana by-the-way) with 203mm rotors on both the front and rear. I know this is a bit of overkill, but I would rather be safe than sorry! What I am looking for is anyone that knows of any problems I will incure with this set-up. Will the 203mm rotor have enough clearence in the rear? Will this be to much stopping power, or is there such a thing as to much? Etc. Etc. Etc. Thanks for any input you can offer!
