quite easy to fit the hardest bit is getting the little barrel out of the old leaver you have to knock the bush out but you get a bit of turned down ali to do it with the pazzo leavers which i thought was good took me about 20min to do both im pleased with them
I bought a pair at the ally pally show last year and they fitted ok but the clutch side master cylinder 'plunger' that had to come off of the original brembo unit didn't go into the master cylinder far enough. I emailed and tried to call the UK distributor and the company in the USA for advice and NOTHING.
I eventually got them to work just fine but **** back up from the companies.
