Description
The SSR Professor SP1 is a classic 3-piece Japanese wheel from the Professor series, featuring underhead assembly. Often compared to the WORK Meister S1 due to similar spoke design, the SP1 is a collector's piece with a distinctly different face profile on close inspection. Available in 17–19 inch diameters.
