I bought these to re-build a 1976 raleigh road bike into a CX bike and they have been great.
I am using 700C wheels in lieu of 27" - so i needed a brake with extra long reach and these got the job done with room to spare. They mounted very simply (same bolt diameter as previously on the Raleigh) and look awesome. These have a great chromed out look that is super fresh and shiny.
I bought some tektro road levers to actuate the brake, and the combo has been great.
I recommend these for anyone needing a long reach brake.
