Thank you for purchasing an All-City Standard track hub. Our hubs feature a high-flange design, sealed
cartridge bearings and proprietary 15mm axles. The axle design of our hubs allows the bearings to self adjust.
When mounted properly in your frame/fork the bearings are properly loaded. Before we go any further there
are a few key things you should know.
WARNING:
CYCLING CAN BE DANGEROUS. BICYCLE PRODUCTS SHOULD BE INSTALLED AND
SERVICED BY A PROFESSIONAL MECHANIC. NEVER MODIFY YOUR BICYCLE OR ACCESSORIES. READ
AND FOLLOW ALL PRODUCT INSTRUCTIONS AND WARNINGS INCLUDING INFORMATION ON THE
MANUFACTURER’S WEBSITE. INSPECT YOUR BICYCLE BEFORE EVERY RIDE. ALWAYS WEAR A HELMET.
Additional Product and Safety Information can be found at the website: www.allcitycycles.com/safety.
WARNING:
A fixed-gear hub is designed to be used with a track cog and lockring. Neglecting to use
a reverse-thread lockring with the track cog can result in loss of control or damage to the bicycle and/or
serious injury or death to the rider, and voids the warranty.
WARNING:
Your bicycle must be equipped with hand brakes when using a singlespeed freewheel.
Do not install a freewheel on the “fixed” side.
Compatibility
Your rear hub is either “fixed/fixed” or “fixed/free.” See below:
Fixed/Fixed
This means that both sides of the hub are designed for fixed-gear
cycling. Both sides are stepped, with two different threading patterns.
The inside threads (1.37" x 24 tpi) require a track cog. The outside
threads are reverse threaded (1.29" x 24 tpi) and require a reverse
threaded lockring (figure 1).
Fixed/Free
One side of the hub is fixed as in the description above. The other side
is threaded (1.37" x 24 tpi) and designed for use with a singlespeed
freewheel. Use only English standard threaded freewheels, cogs and
lockrings (figure 2).
Intended Use
iNTeNded
For track riding, paved roads that are in good condition, and bike paths.
NOT iNTeNded
For off-road or mountain bike use, or for any kind of jumping.
Required Tools
The following tools are required for proper hub installation and installation of the cog or freewheel and
installation on your bike:
15mm wrench
Chain whip
Lockring spanner
Torque wrench with 15mm socket
Grease
Track Cog & Lockring Installation
COg iNsTallaTiON
1. Apply a liberal amount of grease to the cog’s threads.
2. Thread the cog clockwise onto the larger set of hub threads. The cog should go on fairly smooth.
Don’t cross thread it. If in doubt, back it off and start again.
3. Once cog is snugly threaded onto the hub use a chain whip to tighten it completely.
lOCkriNg iNsTallaTiON
1. Our lockrings use English threads (1.29" x 24 tpi LH). Be sure the lockring threads are compatible with your
hub before installation.
2. Apply grease to the lockring threads.
3. Thread the lockring onto the hub counterclockwise. Use a lockring spanner to tighten the lockring firmly
against the cog.
NOTE:
Make sure the lockring and hub threads are completely engaged prior to use.
NOTE:
After the first ride check the tightness of the lockring. By riding you will likely have tightened the cog
further onto the hub, and the lockring will need to retightened against it.
NOTE:
Periodically check the tightness of both the cog and the lockring.
Freewheel Installation
1. Apply grease to the threads of the freewheel. Thread the freewheel onto the hub by hand.
NOTE:
If the freewheel is difficult to thread on, STOP! Back it off and try again. Make sure it is aligned
properly and is not cross threading on the hub. Threads that have been destroyed by cross threading will
not be covered under warranty.
2. Fully tighten the freewheel onto the hub using the chain whip.
Axle Nut Installation
WARNING:
Do not exceed 40Nm of torque on your axle nuts. Over tightening may lead to thread failure.
When installing the hubs into your bikes dropouts, grease the axle bolts thoroughly and tighten with
a 15mm wrench.
NOTE:
A 15mm wrench inside the axle serves to stabilize the axle if you have difficulties loosening an axle
bolt. Simply remove the opposite bolt that is not stuck and insert a 6mm hex wrench into the broach. With the
wrench in place you should easily be able to loosen the other axle bolt.
Wheel Building with All-City Hubs
All-City recommends using a 3-cross lacing pattern. Many builders push down on the rim with the axle against
a hard surface to stress-relieve the spokes. If you use this method, the axle bolts must be completely removed.
Failure to do so may lead to the hub bearings becoming dislodged from hub shell.
WARNING:
ALL-CITY TRACK HUBS ARE NOT DESIGNED TO BE LACED RADIALLY. HUBS THAT ARE
BUILT WITH RADIAL LACING WILL NOT BE COVERED BY WARRANTY.
