Currently looking at upgrading Tektro R559 brakes for Paul Racer, but I am trying to find a clear answer on the reach aspect which is difficult.
R559 are said to guarantee a reach of 55 to 73mm, I assume it is the usual measurement from center bolt to brake pads vertically
Paul Racer are said to guarantee a reach of 57 to 73mm, but diagonally measured from center bolt to brake pads diagonally.
Are they the only bike company that use this method and if so why the fuck do they do that?
And how do I know if it can mount on my frame/wheels?
As it is a conversion from 700 to 650B and thus I am not at the limit of R559 reach but quite far still so I am not sure the Racer will fit, and I find it difficult to measure. Anyone would have any info on that?
EDIT: and if anyone has tried both, is the Racer worth it in terms of breaking performance? I already have koolstop pads on the R559
