What brake adaptors?

[bigbadjake]

Help please looking to convert my current 180 front 160 rear formula R1 discs to 203 front and 180 rear (heard you cannot go over 180 on the rear) on my yeti sb66 but have no idea what mounts I need to space them for the new size.

Would appreciate if someone can recommend what adaptors (share links) and as I have fox 36 forks cannot use floating rotors as not enough clearance so would like to here anyone's suggestions for best rotors (solid).

Any help or advice appreciated cheers

You'll just need a post mount plus 20 adaptor.

A picture of the brakes will help.

Just checked mine for my Formula The Ones on a Fox PM and the Formula mounting hardware has the following stamped on it:
From PM 6" to 203.

So the following in UK (but out of stock in CR and many other places)
www.chainreactioncycles.com/formula-front-203mm-pm6-adaptor/rp-prod76026

From UK (in stock)
www.probikesupply.com/formula-disc-brake-adapter-kits/#

From US
www.artscyclery.com/Formula_Disc_Brake_Adapter_PM6-_203mm/descpage-FRRAKFPM03.html

Part number looks like :FD40148-10

So if its the same on the R1s as The Ones it should work but you'll need to confirm yourself with the supplier. Not got a 180 on the back just a 160 but presume its
PM to 180...

Great just noticed supplied without adaptors need new discs anyway!!

[bigbadjake]

Rocket just ordered adaptors from pro bike but says they are coming from USA!!

[Andrew]

Hope you don't have to pay tax!

Did you check silverfish store for the adaptors?

[bigbadjake]

No just ordered them nightmare as everyone has is mount but no post mounts!!!

Ahh yeah sorry m8 the price was in £ so didn't realise. Try cancelling?

I also struggled at the time I recall as very few places stock them.. Pretty sure I got mine off Chain Reaction or Wiggle
in the kit version with solid discs.

Anyway CR have the Front 203s in stock:

Well discs fitted adaptors came from America in about 6 days and posted straight through letterbox no tax to be paid so cannot fault pro bike first class service, rotors from England took 4 days!!
