I have Avid Juicy 3 160 rotors on my Specialized Rockhopper Comp. I don't want to waste money buying a new brake set, but I'd like the advatages of having 185mm rotors. Is it possible to get a kit to upgrade the rotor and the neccesary brakets?

What parts would i need to do this?

    You will need new adaptors and rotors but you will need to check the frame and fork are warranted for it

    What is the difference between post and IS mounts.

    I had a quick look on the CRC site and thought these might be the ones, could you please confirm?

    faceplant77, I did a 185 conversion to my old rockhopper with Juicy 3's (as the other guys say it's just a matter of an adaptor bracket and a new rotor. It gave me slightly more braking power due to the increased leverage, however it wasn't a night and day difference. I've got Elixir CR on the Stumpy and they are awesome compared to the Juicy's.

    I think you need to ask yourself do you really need it?

    I changed rear 160mm to 180mm. After a little while I actually dropped the rear back down to 160mm as my Saint brakes were locking up the wheel more often than not and I only want the rear brake to scrub speed not put me in a position to lose control.

    With something less powerful (i.e. The Juicy 3) you'll probably find it does help bring the bike to a halt quicker, but is it at the expense of control?

    Got Juicy 3s + 203mm rotors here. Plenty of stopping power :)

    I'm happy with a 180mm rotor at the front and 160mm at the rear, I've easily got enough stopping power.
