hi – have just bought some post mount Revelations. Currently have standard mount Hope Mono M4 caliper(the old gold and black one) with what I thought was 180mm disc but wondering if it is actually 183mm. I know I need an adapter which requires bigger disc (+ 20mm) but does it matter if this is a 200mm or 203mm – Hope seem to do both?

thanks

iirc either size should fit.

will be OK – at the worst, a little washer under it would do the trick

just in case someone was following this………………

203mm disc doesn't fit the 180mm (#3) caliper with +20mm adapter, but as scaredpants rightly pointed out, a little washer between fork mount and adapter sorts it out fine, moving the caliper out a bit

thanks all

TOP TIP!!, I was just about to do the same upgrade, Hope M4 No.3 (gold one) onto Fox post mount with adaptor & 20mm disc upgrade, thanks for the tip all works sweetly now.
