I can find plenty of 'long-reach' calipers with a 57mm maximum reach (such as R536 or its predecessor 521AG).
Please can you tell me how much into the R556's reach you actually need for using with R390 451 rims and if you think a 57mm reach caliper would do the job. From the photo it looks like your brake pads are set at the low end of the reach adjustment. If yours were only 2mm into the adjustment then a 57mm-reach caliper would
Or does anyone else out there know any other brake calipers that definately work with the swift with 451 rims?
Interestingly, I am using the extra long reach brakes at the most retracted position I believe. (~55-57 mm). I don't have a ruler on me right now, but a 57mm long reach set just might work w/ 451 rims. I got the long reach brakes to be safe, but you're right, you probably need just a standard set of "long-reach" brakes.
