I think the adaptor is meant to convert it to a rear?? But it looks like it'd work like this (there's an arrow with 'FWD' indicated which is now pointed more upwards than forwards).
Unless someone can suggest otherwise - and a better alternative??
Adaptors are the same for front and read, the only difference that a the same adaptor requires a +20 rotor when fitted on the front, compared to the rear.
Well.. I only have 160 rotors to check but it does look like it'll slot in and not snag or anything...
Needs a 180 rotor (backing up the +20mm thing ).. keeping my peepers fixed on ebay for something that ends with just my bid
Worst that could happen... it's disc brakes.. the devils work.. anything could happen.. cross-dimensional vortexes (vortices?), gateways to the underworld, a veritable End of Days...
Or the thing snaps, catches in the spokes and the Wife does her very best Supergirl impression in a largely horizontal direction...
