hydro disk

[Sloggy]

Hey all quick Q after trying to get LBS to fix my avid juicy 3.5 to stop wheel drag we decided it would be easier just to upgrade the disk to avid juicy 7's

what worries me is when i went to fetch the bike the front rotor was bigger than the back (front 180 something and back 160) the mechanic said it is because of the travel of the shock Fox 32 F100 RL fork 100 travel

Is this normal or is he telling me rubbish

I stand to be corrected, but I think the standard rotor size of Juicy 7s is 160mm. Either way, rotor size is not directly connected to shock travel. A 100mm fork can DEFINITELY take 160mm rotors. Bigger rotors generally require spacers between the calipers and the mount on the fork. Check if there are spacers in there... If yes, then you can always put in a smaller rotor...

It's quite normal to have different size rotors... More stopping power for the front brake.

 

 

 

I'm not sure of his reason though, don't see his point...

got zip to do with the travel. Larger brake rotor purely for added stopping power as others have already pointed out. Front brake is best for stopping in most situation anyways.

 

AFAIK, the stock/minimum size for all avid rotors is 160mm. Only gets bigger from then.

thanks guys wonder why he put on 185 disk in the front must cost more money (he told me got to do with the travel) then he realized he put 1 to many spacers and removed 1) the good news is the brakes are not touching (no drag) for the first time

I have Avid 140mm rotor on rear.

rite you are ken! I stand corrected on the minimum disk size:avid have 140mm. Most avid brake kits ship with 160mm.

so just be satisfied it works and plunder on is what you hubbers are saying i cant damage the product correct i sound so amature MTBiker which i am
