  1. That sure looks like an Amp/Hayes cable actuated hydraulic brake. I now feel very old despite being just 31 years young!

  2. AMP Research cable actuated caliper and 1st gen disc. I’m still running a second gen disc (floating design) I got at Interbike Philly in 1995 on my ’95 S-Works FSR

  3. AMP disc for sure – I would say circa 1995.
    Remember seeing it reviewed in a german MTB magazine – I think the caliper sheared off the fork, or the disc off the hub.
    At least it is not anodised purple

What do you think?
