The new 1550-gram, lightweight race single-speed/fixed-gear wheelset combines style and speed with a new, lighter rim set that is also wider and has a deeper profile. It features silver low-flange hubs, black aero-profile rims with a silver machined braking surface, and 3x cross-laced double-butted spokes. The specially designed fixed/fixed hubs have extra depth for easier freewheel compatibility, supporting both single-speed and fixed riding.

This wheelset includes rim tape, one lockring, one fixed cog spacer, and an Origin8 chain tensioner (color chosen from drop-down menu).

Note: Given this is a lightweight race wheelset, we recommend a rider weight of 200 pounds and normal street use only. This wheelset should not be used for off-road, cargo, or rough urban riding (potholes, curb hops, etc.).

Notes

IMPORTANT: These wheels require rear dropouts that are at least 5mm thick. You'll need to use the provided chain tensioner to ensure the proper clamp if they are less than 5mm (or just at 5mm). See our installation page for more info.

Due to the varying thickness of fixed cogs, we recommend using the provided fixed cog spacer when installing a fixed cog to ensure a tight fit between the cog and the lockring. If you need a second spacer, let us know.

These wheels are only for 120mm rear dropout widths (OLD) and can't be used or adapted for wider dropout widths like 126mm.

Installation

See our installation page for guidance, including torque recommendations. Replacement wheel bearings also available.
