Converting 27" to 700c and wanted to replace the old calipers with new dual pivots. Best option I could find was a pair of Tektro R559s with a 55-73mm reach. My best measurements say I only need the 55mm reach on these so the brake pads are pushed all the way up in the brace. Is there a downside to this? It looks kind of lame but fits.
I know the Tektro R539 exists but I've had trouble finding them in a nutted bolt version and I don't really want to drill out for recessed.
