Need to know if there are any options for brake calipers on my newest build. I am working on building an All-City Big Block. All I have left is the brake calipers. On the All-City website they list a complete Big Block as having Tektro R538 calipers. I also saw these brakes on the Rivendell website referred to as "big mouth" brakes that allow for wider tires without the need to deflate them to remove the wheel.

Any other options that you can think of. I'm not opposed to the Tektros, just wondering.
