Set of Zip 24 hole ZM900 hubs for mountain bike. Zip hubs are made by SRAM. They came on my new bike purchased Aug. 2025. They were on the bike for less than 6 months and have just a few hundred miles on them. I had a bike shop change them out for a pair of Hope hubs (Nerd biker upgrade). As part of the hub change out I had the bike shop put new bearings in these hubs so they are essentially brand new with no wear on the bearrings. These hubs sell for over $350.00 for the pair. I'm asking $120.00 OBO. Text 801-541-4319 if interested. Payment method is cash only, no venmo or other payment types accepted.
