The new 2018 Haro Lineage Cassette Wheel Set is made to look just like the original Peregrine Super Pro but updated with a 14mm rear cassette hub. Haro set these wheels up with 2 options. You can do the 48 spoke version or the 36 spoke version. Both use a 14mm rear axle and 9t driver and the front uses a 3/8″ axle.
