New Rotor questions.

DoubleHelix

I am thinking about upgrading the 160mm front rotor on my rockhopper pro. It has Avid Juicy 3's brakes.

I know I will need to get a new retention bracket (not sure if that is the actual name) for the caliper to fit a 185mm rotor.

How well does avid fit other manufacturers rotors, or should I stick with a 185mm avid rotor?

Thanks for the help I am pretty new to mountain biking.

as long as it is the correct diameter for the adaptor you will be fine. ( subject to you not wanting fancey rotor that can com into conflict with the caliper/pads).

I have looked at a couple online stores and all they had were the rotor but not the adapter. Any suggestions on online stores that carry the adapter would be nice.

Or should I just go to my LBS?

There are loads of adaptors on CRC, Superstar and Merlin. If you going to use an Avid 185mm rotor you will need a front 185mm IS to PM adaptor or a 185 mm PM to PM adaptor, depending on your forks.

But non-floating rotors are very, very much the same. There are lighter ones (usually thinner) and inexpensive ones but IME the level of interchangeability is astonishing they just go together with the calipers like Lego.

Shimano RT76 rotors are most excellent.

Thanks .blitz those sites are great!

The fork is a Rock Shox Recon SL which is IS if I am not mistaken. What are non-floating rotors?

floating disc "float" on the spider, the braking surface and spider are two parts held together by rivets. The braking surface is free to move sideways to compensate for a warped rotor

if you opt for hope floating rotors you will need to get your LBS to shave the calipers a fraction as the rivets just catch, had mine done and they work just fine now
