I\'ve been offered some Stoptech St-40 calipers second hand.
Now firstly, I\'d never heard of them, but it appears they have been going since 1998 and have a good following in the USA. They also seem to actually come up with their own designs and innovations which I like, and appear to be a quality product.
However, I\'d love to hear from anybody that\'s actually used them to know what they are like?
