The Haro Baseline U-Brake is a fantastic entry into the Baseline model series providing a cost effective and easy to install brake caliper. Installation and adjustment is made extremely simple with Springhanger system eliminating the need to perfectly match individual spring rates in order to have the brake pads contact the rim properly. Plus, the lack of conventional springs leaves extra room around the brake bosses for big tires. Take the hard work out of brake installation with the Haro Baseline U-Brake. 


  • Forged 6061 aluminum
  • Springhanger technology for easy self-adjustment
  • SPS system pads with female bolts
  • Extra clearance for big tires
  • Specifications:
    5.54 oz

This is the same U-brake as the "Haro 78" one that is now discontinued. Guess Haro is labeling all their new parts "Baseline".
Nonetheless, this rear brake is amazing, not sure why the other reviewer gave it 1 star. It is very easy to install and adjust. Compared to the Tektro 907 rear brake I had, this one has noticeably more clamping force thanks to the metal spring-hanger design which works so much better than straddle cables. Forget those clear (and super noisy) brake pads, this Haro U-brake is really all you need to get much better braking. I can lock the rear wheel using normal compound (black) brake pads and I use a gyro/detangler.

Bought these to replace the stock brakes on my cult 29”. I kept coming back to these because of the design. The spring hangar works flawlessly and really stiffens up the brakes. Locks up my rear wheel easily now. Hard to believe that Haro sells these for such a low price.

don't bother I'm kind of disappointed since I love Haro Bikes.
