I am building up a 1983 Motobecane Super Mirage frame and fork.

Brakes are being a challenge as the front needs 62mm reach, back is 55mm.

Tektro makes the 559 which has the reach but is for wide tires/rims, I am using nominal 19.5mm wide (700c) rims.

I would like to avoid using centerpulls for the added hardware that must hang from the seatpost bolt and head top bearing area and because newer dual-pivots probably work better.

Any comments or suggestions would be appreciated.

Why do you consider the 559 unsuitable? Appearance? Functionality? So what if they say they are for wider rims/tires. They should still work.

I agree with CV-6. The long arms will clear big tires but I haven't seen anything suggesting that they are designed for wide rims. If you ask me, all brakes are designed for wide rims.

i used the 539/559 combination on a couple 700c conversions where i could use the shorter caliper on the front, and the longer model on the rear. they don't look exactly period correct, but they do perform wonderfully.

Thank you for the comments. I have ordered the Tektro 539 rear and 559 front.
