shimano brake adaptors

my mates after some 180mm adaptors for his xt brakes – on his anthem x2 he has no adaptor at all the caliper goes straight on to the fork so assuming its at 160mm at the mo??

which adaptor will he need folks to go 180mm?

this??

Which in Shimano speak is an SM-MA-F180 P/P2. Just bought one meself from Wiggle, cost about seven quid…

Looks like Shimano have changed it slightly but yes, that one will be fine.
It used to be part number SM-MA-F180P/P

As DT says, any 160mm post to 180mm post will do the job.

cheers guys ! what about the rear one for a 180? assuming all rears are IS? so just need a rear is to is 180mm?

There’s three from Shimano out there that’ll do the job (front I’m talking about), and many from others, like Superstar, Ashima etc. :-

Shimano SM-MA-F180 P/P – the original shimano one which offsets the caliper from the original mounting holes

Shimano SM-MA-F180 P/P2 – the new one from Shimano which uses the same mounting holes

Shimano SM-MA90-F180P/P – the XTR version of the P2, and the one shown in your link to Ebay.

Take your choice…..

cheers folks, any one know where they are actually in stock good to go? front post mount 180mm and rear 180 is then? cant see any in stock at wiggle etc

Do the front and try it with 180F/160R first. That may be enough.

If you do decide to go 180 rear too, then you’ll probably NOT want to adapt IS to IS!!! as you’ll already likely have an adapter on the rear to take IS to 160 (post) as this is what you use to centre the caliper around the disc. You’ll want to replace that with a bigger one instead.
You’ll want an IS to 180 post rear like this
SM-MA-R180P/S

Both the SM-MA90-F180 P/P and SM-MA-R180 P/S in stock at CRC – just don’t use your credit card!

cheers guys – thanks for the tip off on superstar – told my mate to order from there, in stock and cheaper! superstar are great for little bits like this and pads!
