Does it matter which rotors?

russ_gillespie

Hiya,

I've bent my front formula rx rotor and the bike shop have true'd it as well as they can but say I may need to replace it. I haven't actually collected the bike and looked at it myself yet so this could all be pointless, but...

...If I was to replace it, do I have to get another (rather expensive) formula rx rotor? Or can I get a superstar flame, for example. I understand that different rotors will affect performance and pad life, but is there any other reason to stick with the same manufacturer, or even the same design?

Thanks,
Russ

As long as the diameter is the same and the mounting to the wheel the same, it matters little what disc (I'm English, rotor is English (US) - to plagiarise form Microsoft) you use, some are better material, some will be lighter, you'll get more or less mud clearance 'holing' but they will all work just fine.

Some disc brakes have wider pads than others, so as well as diameter and thickness also consider width when buying new.

It should be fine.

Of course it matters, you NEED Alligator Aries discs.....

no reall dif... the superstars are great value.

Formula pads are quite narrow, so you can get away with less braking track and less weight.

A disk you might be interested in is the new shimano XT floating rotor (got mine at CRC).

Far higher build quality that the other floating rotors, light and cheaper (than other floaters).

I use them with my Formula the One and am impressed.
