I have a frame built for 27" wheels but need to fit 700c wheels. This makes the caliper drop 65mm
There's plenty of so called 'deep drop' calipers but they all seem to have a max drop of 57mm. The only calipers I can find which cover a drop of 55-73mm are Tektro or Alhonga which look a bit cheap
I've also seen extension pieces used on the rear bridge although I don't know what happens on the front fork?
Does anyone know if these extension pieces are available anywhere to buy or have any other options for 65mm drop calipers?
