Hey guys,
I thought I'd start this thread as a reference for everyone to post up what sort of hydro calipers they're using on their hub motors and what mods were necessary to get them to fit. People often ask me "will the [insert brand and model] brakes that came on my bike fit the motor" etc so I thought it's be good for everyone to state what they've found what what's involved to make them fit - be it a straight bolt up fit, with a washer or 2 or a half inch thick bar of steel jammed in there :lol:
Tell us what the motor you're using and the make and model of your calipers. I guess the 2 most popular ones will be the new style 9C and the new Hx35 crystalytes. The new crystalytes do have a little more clearance than the 9Cs so should be able to accept wider calipers but not by much.
From memory the clearance on the 9C is around 14mm and around 18mm on the crystalyte (from center of the disc to the the side cover of the motor)
I'll edit this first post with everyones findings to make an easy to find list.
I'll kick it off with the new crystalyte Hx35 motors. I've dummy fitted a juicy 3 caliper and it JUST contacts the motor side case. With a 2mm spacer under the disc and the fat washer that comes on the motor on the inside of the frame to push the caliper back out a similar amount it should work fine.
My Clarks S2 that are on on the front miss out by a fair margin though. Not so much the side of the caliper but the 'knuckle' where the hydro hose leaves the caliper sticks out another few mm.
