Hi guys

Looking for some help before I embark on upgrading to larger rotors on my Avid Juicy 3 brakes. I have a 185mm rotor on the front and a 160mm on the rear. I'm buying a new 203mm rotor, which I'll fit onto the front, and will put the 185mm on the rear.

Would someone mind just double checking I have the correct parts before I order please?! :oops:

This 203mm rotor:

Will this come with fixing bolts, will I need to buy new bolts or will the existing set I take off the 185mm or 160mm suffice?

This 203mm adaptor. It's going onto an IS set of RS Revelations, with standard QR:

Again, can anyone tell me if this will come with the relevant fixing bolts or do I need to buy these separate?

Finally, this 185mm adaptor for the rear:

As above, will this have the relevant fixing bolts with it and will the rotor bolts I take off be fine to use when fixing back onto it again at the rear?

Phew! Thanks in advance for any help offered!

    re-use the existing bolts for both new rotor and adaptors.
    the new stuff may come with new bolts but they will fit pretty much the same as the
    old ones.
    shouldn't be any problems either way , its just post mount brakes that have varying bolt
    lengths.

    presuming the same fitting for the fork and frame and the same calipers are being used the adaptors will be the same.

    Can you buy an adapter to fit a 203mm disc to the rear also?

    EDIT: Sorry bit of delving and yes you can. What does the IS bit mean?

    Ok cool thank you. I'll have to go measure mine to see what they are. Nothings straight forward is it...

    The Juicy 3's should be more effective with a larger radius due to more leverage I believe? Cheaper than Codes and I'm sure as inefectual in enqual measure.

    Can you not use the existing front adaptor on the rear rather than buying a new one?....
