Rotors - Is bigger better?

djames77

Hi

I've got a spesh rockhopper fitted with juicy 3's and 160mm rotors. Will changing to 180 or 203 make them better at stopping a big lump? If so, does anyone know if superstar ones will fit?

Thanks

J

Thanks Nick

Any idea if Superstar rotors will fit? runninkg alex rims and avids

Yes. With the necessary adapters.

Yes.

Because you are a male, bigger is always better.

No justification is needed.
You shouldn't really even be asking the question.

Don't fit 203 rear rotors. I find them too much even for downhill with one finger braking, either on or off with nothing in between.
I am pretty large (16 stone) and find 185 front & 160 rear avid juicy 3s fine for trail riding. Juicy's do need regular maintenance & I find clarks pads much better than Avids.

203's are too big always warp!

Thanks everyone. I think i'm going for 180 from and back from Superstar and clarks pads. Get the LBS to fit whilst giving the brakes a service. Seems like this should ensure i can stop!

Been running 203's(Avid/Hope) on various bikes for 5 or 6 years and never had one warp 8)I've had one go yellow(strawing)with heat and it's still on the bike and perfect

Hi
ive run 203s for years
there only as agressive as you make them
and ive also never warped a disc why would you .

i like a 203 at the front and a 180 at the back.

never warped a disc (or is that disk) (or is that rotor) i am very heavy and my brakes work hard for their money.

i do find a bigger disc gives me more stopping power.

I run 203 on the front and 185 on rear, I would start with leaving the rear alone and just buying a 185 front. If you still want bigger then you can move it to the rear and upgrade.

I'm not sure if J3s are warranted to run 203mm?

You can get a lot more power (particularly in the dry) by going for the superstar kevlar pads which are very good at stopping you in the dry.
