AMP Research research

[Swede]

Looking at the D1 instructions there are only two “calliper mounts” but I found a WI/RX hub on eBay last night with a 180mm rotor.

There must be different/longer options as this is what’s done with the adapter plates on modern bikes. Something doesn’t stack up…

GT had a “special” but there are no part numbers on the ones I have.

I can't remember the numbers, but didn't the Rock Shox rotors supplied with the gold Rock Shox calipers have a different diameter to the original AMP ones?...and presumably a mount option to fit a 180mm rotor.
I had a client try to fit RS calipers and rotors onto AMP mounts on an AMP frame and they fouled like yours.

The RS rotors work fine with the ISO-fit mounts on ISO frames and forks, but don't run on AMP frames or forks with the original AMP mounts.

All the best,

They feel a little loosey goosey on the rear at first, but once you get used to the characteristic of the frame, they’re awesome!!!

The diameter of this NOS rotor is 163mm so I think the difference must be the bracket.

In process of rebuilding my b3 with f3 forks and somehow I’ve lost the spring for the front forks . Anyone have for sale or where i can get something similar

According to the Brakestuff website the diameter of the rear is 133mm - that's not what I have!View attachment 794839

Did you end up finding rotors, or trimming your current ones down??
I might have some amp rotors in my parts bin

 

[Swede]

No, I’ve been distracted with other protects... If you could let me know what size you have, I think that will help solve this mystery.

lovely collection you have there


AMP's a brand I've never owned but always wanted one

Any interest in the Benz\Amp B5 out of New York?

F1... was it 1.00 or 1.125"?

I need your help… is this an AMP or a Norleen shock?
