Koozer XM1850 (622x27) wheelset

And this is the third step to 29x2.1 wheels for my Cannondale Cujo 1 (after tubes and tires).

Koozer XM1850 (622x27) wheelset, ready to mount.

My configuration:

Front hub (Koozer 450): 15x110 Boost

Rear hub (Koozer 450): 141 QR Boost (with caps and axle included)

Cassette splines: [Shimano] HG

Brake rotor mount: 6-bolt

Spokes: 32 per wheel

Strange rear hub design: the freehub [cassette] body (with splines for a cassette) is mounted on the hub without any fasteners, so it can easily be removed by hand.

And not so easy to reinstall (I did it with a thin wire). Be careful when removing the rear wheel from a bike.
