Hi guys
quick question ive been looking into brake boosters as ive noticed my frame flexes alot when i squeeze,
i have a MAD Phase 1.2 ive measured the centre to centre hole and its 90mm on upper and lower, all the 2 bolt boosters are 95mm upwards so these wont fit however i clicked on the 4 bolt and some of them are 90mm to 110mm i take it these would fit is there a big difference other than the extra bit of metal between 2 and 4 bolt, anyone recommend a good 4 bolt or someone know a 2 bolt that will fit 90mm spacing
thanks guys
