Hi there!
In another thread I already mentioned that I have some discbrake adapters for sale to fit on a few types of bike frames from the end 90's to early 00's.
Only a few years Brands like Trek, Gary Fisher, Klein and perhaps a few others, made their frames to fit 22mm chainstay discbrakes of Hayes. The so called 'parallel mount'. This standard only lived for a few years, till the nowadays mounting stds, like flat- and postmount came up.
These frames however, are still alive and kicking.
Myself I own a 1999 GF Mt Tam, which I may upgrade to discbrakes in the future, but is nowadays still running wild with Magura rim brakes. First I am doing a project to create Gravel bike based on a vintage Trek sl mtb frame also prepared with the rare discbrake mounts. So I had to have discbrake adapters to fit some nice Hope flatmounts. Since laser uiting multiple precies is much cheaper then Just 1 or 2, I had made more and are some left for sale...
Lightweight, made of aluminum. They can go for 15 euro's each and shipping costs.
See picture below. Let me know if your interested. I'm based in NL, so please consider that in case of shipping.
Kind regards,
Mr. Orange
