Hope disc brakes

[baron von greenback]

Can anyone tell the distance between the bolts on the calliper were you attach to frame on
Tech 4 v4
Tech 3 v3
Tech E4
Tech E3
Or are they all the same size I am comparing them to early hope brakes which are 43mm thanks

All 74mm. Post mount standard.
Every modern mtb fork uses this spacing and most frames, although some frames still have IS tabs and use an adaptor to run post mount brakes.
