Changing Rotor Sizes
I have some Hayes 9 disk brakes with 6" rotors. I would like to go to
an 8" rotor up front. Since hayes brakes have their own mounting adaptors, can I simply put on a bigger rotor and change the mounting adaptor or is there more to it? If so, where can I get the different adaptor? Mike |

Mike Yes, it's so simpel but check first the manual of your fork, some forks are not recommended to use rotors larger than 6", if the fork fails with a 8" rotor, no warranty, FR or DH forks with a 20mm thru axel are durable enough. |

Changing Rotor Sizes
Is it likely that fork that will withstand the moment (force x distance) of
a 6 inch rotor will fail due to the moment of a 8 inch rotor? "Volker Leimann" wrote in message ... Mike Hales schrieb: I have some Hayes 9 disk brakes with 6" rotors.

Changing Rotor Sizes
That's what I was wondering. I swear that I have seen some Stinky's
with a QR fork and 8" rotors. It seems like the stipulation that it must be a through axle is kind of arbitrary. In fact quite a few forks come in both through axle or QR configurations. It seems to me like the wheel would be more a limiting factor than the fork. Any engineers out there have comments? Mike |

Mike From a long thread at: http://groups.google.com/group/rec.b...c46b9a2e8e997d Jobst said: The smaller the disk diameter, the greater the disengagement force for the same braking effect. Therefore, I see no connection between larger disks and more wheel disengagements. What is less apparent, is that a disk brake puts the same bending force that appears at the fork crown on the end of the single fork blade at the caliper. This severe bending moment is the reason not to put a disk brake on a conventional bicycle (road) fork with a slender blade end, an end that is not intended to carry bending loads like those at the large diameter end at the fork crown. ----------------- If you want to read more, be sure to get some popcorn.
