tubus Clamp Adapter for Seatstay Mount

OK

It gave some extra years to my commuter-tourer-mtb aluminum bike. After a lot of abbuse, one of the rack mounts went stripped, and these adapters saved the day. It is actually firmer than mounting the rack directly to the frame in my opinion, as it is flat and it is made of steel. I don't know if it scratches the paint, but I would not care, as my intention is to leave it permanently. Unless it was a carbon frame that could be structurally damaged. No signs of rust yet (4 years), and not only for Tubus racks, of course.

installs very easy and keeps everything in place
use it for commuting, laptop + sporting gear

great product!

Effective, but should come with some protection to prevent scratching of the frame. Measure twice, buy once.
