Hayes Adapter For 8" Rotors

Technical Information:

Item: I.S. 20mm Thru Axle Forks, 98-15069 - For 51mm IS 20mm ThruAxle Fork using 8" rotor with 74mm post mount caliper

Item: 74mm Post, 98-15072 - For 74mm post mount fork(thruaxle or QR) using 8" rotor with 74mm post mount caliper.

Item: Boxxer, 98-15071 allows mounting a 8" Hayes disc brake to Rockshox Boxxer forks.

Item: All I.S. Frames, 98-15074 Rear 51mm mount on frame using 8" rotor with 74mm post mount caliper. Some frames cannot accomodate an 8" rotor due to size limitations - check your frame before ordering.

At this time, Jenson USA does not offer an adapter to mount 8" Hayes disc brakes on standard quick release axle forks with 51mm mount, due to manufacturers safety recommendations.

Unsure which adapter is right for your bike? Call us at (888) 880-3811 or email us using our "Help Desk" feature at the top of this page.

Life changing
I didn't expect anything other than me finally being able to run my Marzochhi 888rc with my Hayes nine brakes but everything in my life changed for the better.

Yeah, some would say "that's because you're running dual crowns now" or "its all that extra travel", but we all know better than that, it's this blessed adapter.

PROS: Easy To Install, Lightweight, Sturdy Design

This rotor is amazing. It lasts a lifetime, looks awesome on the bike, cheap price but definitely worth it, I would spend $60 on this rotor any day.

I have 8in
I have 8in. rotors with this adapter on my Fox Float. I am using azonic wheels, and at first every time I would squeeze the brakes my quick release would loosen up, no mater how tight it was put on. I changed the azonic skewers to salsa skewers and have been dirtjumping and doing endos and have not had a single problem with them since. I do take the wheel off every ride and check it though. BTW I am running Hayes El Camino's which aren't the most powerful brakes out there, so use caution when using 8in. rotors on QR axles.

Does Its Job
Bought 6" PM front To 8" rotor and it worked great with:
- Fox 831 fork with 15mm thru axle
- Hayes Stoker Ryde
- Hayes 8" rotor

Adapter must be 100% tightened down before putting brake on (limits adjustablity side to side)

PROS: Sturdy Design

CONS: Adjusting

will this work on a back brake rotor?
A shopper on Jul 27, 2017
BEST ANSWER: I can't be sure but I would imagine yes since it was the same as the front one it replaced just longer posts. For the money it's not
Much of a gamble
Can you please tell me what the letters I.S. means when you're describing forks and frames
