Avid Shorty 4 Rim Brake 2013
Designed for modern Cyclocross conditions and equipment, they are also perfect for Trekking and Touring bicycles. Less noisy than other rim brakes, the center mount pad reduces fork vibration.
I got these just to get my CX bike rolling and after one stint on a rolling mountain road, I am ready to upgrade. They seriously lack power compared to me Rival roadie. The pads are the weakest point, so if cost is an issue, at least get the Shorty 6. The geometry is the second issue, so I would suggest if your wallet can manage it, get one with wider arms for the front.
