My beanroller has a single front brake, with the cross lever on the bar top (just like everyone else's)... But I'm gonna go with hoods and need to add a rear brake.

So, need recommendations on the calipers... Silver, not black... I know I need long reach (47-57mm... some call them "standard reach"). Tektro, most likely. (Although, I went to www.tektro.com today to check out the products and the domain has expired! Nice.)

I could just get this rear caliper (Tektro A536) for $15 at Amazon...

that might be the cheap and easy way to go. But any thoughts on which ones? Or replace the existing front and put in a complete set? A556? A538? R730?

My rear seatstay bridge is post-2007, fyi... (as below)
