• B series, is it not a b series in a g series body? (You’d notice if there’s a gap on both end of the caliper allowing it to move back and forth a lots)

  • So, you reckon I could get a G04S pad and it'll be fine? They look close enough so I presume they'll fit and if rotors are the same size. Stupid product codes.

  • The caliper is made for a G (or J too if you wanna go finned) and as +edscoble pointed out, B fits but there's a much bigger parallel gap between the caliper and pads which causes rocking or juddering under heavy breaking.

    YMMV, B in a G caliper works ok, which is probably why you've not noticed it.

    Also, curious why are you using Elvedes pads? Stop gap (pun intended!) during the Shimano factory fire + COVID + Evergreen shortage?

    Can't find my G spare pads but this the compatibility list from the J04C.
