I have a 2021 Trek Roscoe 7 and I’m looking to buy a rear Hope Pro 4 hub. My Trek comes stock with a Formula DC-2241 rear hub, alloy, 6 bolt, Shimano 8/9/10 freehub, Boost141, 5mm QR. The rims are Bontrager Line 40, 28-hole, 40mm width. I’ve done some research and one person had to buy a QR141 adapter to fit a 148mm Hope Pro 4 rear hub. Is this what I need to replace my stock hub or is there an easier or better way?

You need the Hope HUB238 conversion kit.

It will convert Hope Pro 4 hubs to quick release. Boost Thru Axle will become QR Boost 141mm. 142mm Thru Axle will become standard QR 135mm.

Description taken from an online Shop:

  • Converts Hope Pro 4 BOOST hub (148mm) to QR Boost (141mm)
  • Converts Hope Pro 4 142mm to QR (135mm)
