This is a pair of aluminum brake adapters that allow you to run modern 4 pad BREMBO calipers with 40mm spacing on Marzocchi forks designed for F08 calipers - if you use a 280mm rotor. You can also swap them side for side and use them on 300mm rotors. Sold in pairs.
Quality - the caliper mount adapters themselves were well made and incredibly light
Fitment - I bought these mounts in a bid to mount modern callipers on my '84 BMW R65, test fits & mock up's showed promise but without a full bolt up I would not be able to guarantee compatibility but it's safe to say that if the Brembo F08 callipers are identical in their mount spacing as the Brembo P08 callipers
Overall - Steve was pretty helpful in organising the order and making the best educated guess he could from half a world away & the quality along with the low weight of the adapters make them a good buy for an easy set up
