An ever present headache with "normal fixed hubs" is the assembly of a drive cog that is attached by a thread being pulled in both directions by the pedal torque. Of course, the traditional solution to avoiding the cog unwinding itself from the hub in the reverse direction is a left hand threaded lockring, butted up tight against the cog. But as many riders have found out, this historic system can be relatively volatile.

Halo thought. . . There has to be a better way: A splined hub body (with cogs that slide on) and an independent lockring. . . That never has to handle rotational forces from the drive.

The Halo Fix-G hub features a fixed HG spline machined as part of the alloy main hub body*, with a conventional internal thread for a standard HG type lockring (with easy tool fittings) and options on left hand side for conventional fixed or freewheel threads.

*Note: Must ONLY ever be used with "7mm base Wide Foot" cogs (to avoid the cog biting into the alloy splines on the hub) such as:
- Halo "Fat Foot" 1/8 cogs
- Gusset "Double Six" 5/64 cogs
- Regular width HG cogs should never be used

Halo Fix-G Advantages:
- Easy and secure fixing and servicing
- Adjustable chainline
- Twin cog options (can run 2 cogs together)
- Accepts from 12T+ cogs (for compact gearing)
- No need for chainwhip tools

Tech Features:
- Hi-polish custom CNC machined hub shell
- HG type fixed spline
- Japanese sealed bearings
- Hollow M10 Cr-Mo axle
- 120 mm spacing
- 22 mm "Large Cone-Faces" to avoid damage to frame
- Supplied with cog spacers and alloy locking
- Laser logo
- 32H, 36H or 48H
- HG Fixed / Fixed or HG Fixed / Freewheel Types

Important Note: Threads for "Fixed Cog Lockrings"
- Hubs must only be used with ISO standard 1.29" x 24 TPi L/H fixed cogs lockrings
- Do NOT USE French (1.32" x 24 TPi) or Italian (33 x 1 mm) standard lockrings
- The larger diameter French and Italian lockrings may appear to work, but, will strip the threads from the ISO hub

Questions & Answers (1)
Are Lockring And Spacers Included?
06 Jan 2015
SJS Customer Service:

There should be 3 spacers and the lockring for the splined side included. If you go for one of the hubs with the threading to take a normal fixed sprocket on the opposite side, the lockring for that will need to be purchased separately.
