Tektro CR720 Cantilever Brakes
The CR720 brakes are certainly the best deal in canti brakes today. They feature forged aluminum arms, linear spring design, and dual micro tension adjusters, so adjusting and setting them up is particularly easy. Though the look is retro, their geometry makes for a very powerful brake.
Includes straddle wires, really nice hangers, and all other required hardware. The finish is silver satin.
The price is per brake, or one wheel's worth.
