The US-B Nuevo is a top-of-the-line clipless pedal with superbly smooth cartridge bearings. The retention system is similar to that of the Time ATAC pedals, and the cleats are interchangeable. Two metal bars engage the cleat that has the same 2-bolt mounting pattern as SPD cleats.
The advantage of this system over SPD pedals is greater float with no self-centering, making these pedals a good choice for riders with knee problems. The super-smooth cartridge bearings will keep them spinning smoothly for years to come.
