tamination of the bearings.  
After completing assembly of the hub, check its function by spinning the axle with your fingers. It  
should rotate freely without irregular friction. A small amount of lateral play is acceptable if the play is  
eliminated when the wheel is installed with the quick release properly closed.  
Clean and inspect the parts  
1. Use solvent to completely remove all old grease and  
debris from the hub, axle, and axle parts.  
2. Inspect the bearing running surfaces of both the  
ball cones and the ball cups (inside the hub). Replace any  
cones. If the cups are worn, replace the hub shell.  
Lubricate bearings and threads  
1. Lubricate the threads on the axle with Wrench  
Force™ synthetic grease, or a similar product.  
2. Place a bead of grease all the way around each ball  
cup, sufficient to hold the balls.

slightly protrudes past the end  
of the axle.  
9. Press the axle end caps  
into both ends of the axle.  
After completing assembly of the hub, check its function by  
spinning the axle with your fingers. It should rotate freely  
without irregular friction. A small amount of lateral play  
is acceptable if the play is eliminated when the wheel is  
installed with the quick release properly closed.

seats.  
2. Normally, bearings are not re-used. If you are re-  
installing an old bearing, wipe off any grease or debris  
from both the inner and outer surfaces.  
Do not use solvent on the bearing, as the solvent will  
contaminate the grease. This may cause bearing failure.

Clean and inspect the parts  
1. Wipe old grease or debris from the hub bearing  
seats.  
2. Normally, bearings are not re-used. If you are re-  
installing an old bearing, wipe off any grease or debris  
from both the inner and outer surfaces.  
Do not use solvent on the bearing, as the solvent will  
contaminate the grease. This may cause bearing failure.  
Lubricate bearings and threads  
1. Lubricate the threads on the axle with Wrench  
Force™ synthetic grease, or a similar product.  
2. Lightly grease the inner and outer surfaces of  
each bearing.

Freehub body information (non-DT Swiss)  
FREEHUB BODY RUNNING CHANGE  
INSTALLATION AND REMOVAL  
If the freehub body is worn or damaged, replace it.  
Bontrager rear hubs use an unique freehub body that  
in some cases has encountered removal issues. In these  
cases, a high amount of torque is necessary to remove or  
install the freehub body attachment bolt.  
Removing the freehub body  
1. Follow the Disassembly  
instructions for the hub. Remove  
the axle, and then the right side  
bearings.  
To resolve this problem a running change was made  
to the 2001 product line. The older, direct contact style  
of freehub body has been replaced with a splined freehub  
body attachment. This splined attachment requires less  
bolt torque. Since it is a running change, the following  
information is necessary to identify which freehub body  
is on a wheel.  
2. Determine the correct size  
of allen wrench to engage the  
freehub body attachment bolt.  
3. Unthread the bolt in a  
counter-clockwise direction  
(standard threading).  
If there is a date code stamped on the freehub body  
it probably uses a splined attachment. If there is no date,  
it is a threaded attachment. After May 2000, both styles  
of freehub bodies (both attachment types) will have this  
date mark.  
Fig. 4  
Installing the freehub body  
1. Carefully clean the mating surfaces and threads of  
the freehub body, hub shell, and attachment bolt.  
These different styles of freehub bodies are not inter-  
changeable.  
2. Lubricate the threads of the attachment bolt with  
Wrench Force™ synthetic grease, or a similar product.  
3. Carefully engage the threads of the freehub body  
attachment bolt into the hub shell. The bolt is steel, and  
the hub is aluminum, so cross-threading the bolt will  
result in destruction of the hub shell.  
Identification of freehub bodies  
Threaded freehub body

freehub body, there are two

sure the splines are aligned as you tighten the attachment  
bolt.  
identifiers. First, there is a  
CNC machine line approximately  
10mm from the outside end of  
the freehub body (Fig. 1).  
For the older, threaded style freehub body, tighten the  
freehub attachment bolt to 350 lb•in (40Nm).  
Second, the thread-attached  
freehub body is designed to be  
removed with a 12mm allen  
For the newer, splined design, tighten the freehub  
attachment bolt to 400 lb•in (45.2 Nm).

wrench.  
Splined freehub body  
The newer, splined attach-  
ment (Fig. 2) freehub body has  
no CNC line. Further, it is  
designed to use an 11mm allen  
wrench for removal. A special  
adapter (TCG #211338) is made  
which attaches to an 8mm allen  
wrench to fit the 11mm allen  
head of the freehub attachment

bolt (Fig. 3).  
In addition, as a running  
change the new hub bodies will  
include a 6-digit part number  
embossed on the outside of the  
hub shell where it is plainly vis-  
ible. All hubs with the part num-  
ber visible use the splined free-  
hub body.

from both sides of the hub.  
3. Press the bearing into the hub shell with the bear-  
ing press.  
Fig. 2F  
4. Slide the left bearing onto the axle with the black  
seal facing out. Thread the axle spacer onto the axle, and  
use the bearing press to press the left bearing into the  
hub. The axle should turn freely with no lateral play in  
the hub shell.  
4. Tap the left end of the  
axle with a hammer to drive  
the axle out of the hub.  
5. If inspection shows it  
necessary, remove the washers  
and end nut from the right side  
of the axle.  
5. Place the bearing seals into the hub with the let-  
tered surface facing out.  
6. Thread the axle spacer onto the axle. Place a 17mm  
cone wrench on the axle spacer and a 15mm cone wrench  
on the end nut. Tighten the end nut against the axle spacer.  
After completing assembly of the hub, check its function by spinning the axle with your fingers. It  
should rotate freely without irregular friction. A small amount of lateral play is acceptable if the play is  
eliminated when the wheel is installed with the quick release properly closed.  
End  
nut  
To loosen the end nut, re-  
install the left side axle spacer  
and locknut, and lock the end  
nut against the axle spacer.  
Hold the axle spacer with a cone  
wrench while you loosen the  
right side end nut. Alternately,  
hold the axle with vise grips.

Fig. 4F  
7. If it is necessary to remove  
the freehub body, refer to the Freehub Body  
section, pages Freehub 1 and Freehub 2, for removal and  
installation instructions.  
When overhauling the hub bearings, it is usually not necessary to remove the freehub body.  
Clean and inspect the parts  
1. Wipe old grease or debris from the hub bearing  
seats.  
2. Normally, bearings are not re-used. If you are re-  
installing an old bearing, wipe off any grease or debris  
from both the inner and out surfaces.  
Do not use solvent on the bearing, as the solvent will  
contaminate the grease. This may cause bearing failure.

DT-Swiss Comp series hubs  
Important information before you begin with Comp series hubs  
Tool list for DT Swiss front hubs  
Some Bontrager front hubs utilize DT Swiss internal  
parts. This manual is intended for retailers with the  
appropriate skills and knowledge to work on these hubs.  
Please read the entire section before carrying out any  
kind of maintenance work.  
The following tools may be necessary to perform  
maintenance work on DT Swiss  
Comp series hubs:  
Short  
Long bearing press  
bearing  
Short bearing press  
press  
This manual details the principle design features of  
DT Swiss front hubs and also provides instructions as  
to maintenance and repair work. Please take special care  
to use only original DT Swiss special tools in order to  
undertake the work details in this manual. Use only DT  
Swiss replacement parts.  
DT 17mm cone wrench  
Long  
bearing  
press  
Comp front hub bearing press  
Multi-purpose DT grease  
These maintenance items are  
available as TCG part #211416.  
In this manual, the hubs are shown installed in  
a complete wheel. Maintenance work should be carried  
out on complete wheels where possible. Otherwise, some  
steps can not be carried out correctly.  
Special screw-  
driver  
This manual provides technical and spare parts infor-  
mation for these hubs. If you have further questions  
about these hubs regarding technical information, sup-  
port, or warranty, they should be directed to Bontrager  
Technical Support via phone or on the Bontrager web site  
Front hub bear-  
ing press  
In the event of improper servicing of the hubs,  
Bontrager has the right to refuse any warranty.  
Special information before you begin  
Bearing resistance: New or newly re-built hubs have  
a higher rolling resistance than used hubs because the  
grease in the freehub has not yet been evenly distributed  
and the seals have not yet bedded in.  
Check your work: Before use, always check the hub  
for proper functioning.  
Regular Maintenance  
Maintenance of the front hubs should be performed at  
least once a year. This maintenance schedule is based on  
normal usage. If you ride your bike more than average,  
or in rain, snow, or off road conditions, service your  
bicycle more often than the schedule suggests. If any  
part appears to be malfunctioning, inspect and service it  
immediately.  
Things to avoid  
Avoid high pressure washing systems, like those at  
most car washes. The high pressure can bypass bearing  
seals, letting water into the bearings. Do not use any kind  
of solvents or tensides- this can damage the hub.

not use any kind of solvents or  
tensides- this can damage the hub.  
Some Bontrager hubs utilize DT Swiss internal parts.  
This manual is intended for retailers with the appropriate  
skills and knowledge to work on these hubs. Please read  
the entire section before carrying out any kind of mainte-  
nance work.  
Determining the year of hub  
There are two styles of rear  
This manual details the principle design features of  
DT Swiss hubs and also provides instructions as to main-  
tenance and repair work. Please take special care to use  
only original DT Swiss special tools in order to undertake  
the work details in this manual. Use only DT Swiss  
replacement parts.  
hub, with some unique parts and  
different instructions for assem-  
bly and disassembly. To deter-  
mine which hub type you will be  
working on, it is necessary to  
remove the freehub. With the star  
ratchet removed, you will be able  
to see the right side shell bear-  
ing. If the bearing is completely  
visible due to its 24mm outer  
diameter (Fig. FH5), it’s a year  
2000 hub. The 2001 model uses  
a larger, 28mm diameter bearing  
(Fig. FH6) that is partially cov-  
ered by the ring nut (requiring  
the removal of the ring nut).

In this manual, the hubs are shown installed in a  
complete wheel. Maintenance work should be carried out  
on complete wheels where possible. Otherwise, some steps  
can not be carried out correctly.  
This manual provides technical and spare parts infor-  
mation for these hubs. If you have further questions  
about these hubs regarding technical information, sup-  
port, or warranty, they should be directed to Bontrager  
Technical Support via phone or on the Bontrager web site  
In the event of improper servicing of the hubs,  
Bontrager has the right to refuse any warranty.  
Removing the cassette from the  
freehub body  
The cassette does not need  
Special information before you begin  
to be removed from the freehub  
body to perform regular main-  
tenance. However, if you decide  
to remove it, it should only be  
removed after the hub has been  
completely re-assembled.  
Bearing play: A small amount of play between the free-  
hub body and the hub shell is automatically eliminated when  
the wheel is installed and the quick release is tightened.  
Bearing resistance: New or newly re-built hubs have  
a higher rolling resistance than used hubs because the  
grease in the freehub has not yet been evenly distributed  
and the seals have not yet bedded in.  
1. Release the lockring using  
a lockring tool.  
Aluminum freehub bodies: For hubs with an alumi-  
num freehub body, we recommend cassettes using a solid,  
one piece spider like the Shimano Dura-Ace, Ultegra, XTR,  
or Deore XT. Cassettes using loose or bolted sprockets  
like Shimano Deore LX can cause notches in the freehub  
body. This can cause difficulties when later removing  
the cassettes from the freehub body (see “Removing  
Cassettes” on this page).  
2. Loosen the cassette by lightly  
tapping it counter-clockwise with the  
hammer.

tool  
3. Remove all the sprockets from  
the freehub body.  
4. Use a fine file to remove  
bad notches from the aluminum free-  
hub body (Fig. 14H). The aluminum  
freehub body must be cleaned and  
inspected. If any cracks or other  
damage is visible, the components  
must be replaced.  
Note: Notches on the freehub body do not have a negative influence  
on the functionality of the freewheel.  
Short

Check your work: Before use, always check the rear  
hub for proper functioning. Check the freehub body and  
the ratchet mechanism. If they do not function correctly,  
the rear hub should not be used until the fault is cor-  
rected. If you are unable to correct the fault, consult  
Bontrager Technical Support.

Regular Maintenance  
Required tools  
Maintenance of the rear and front hubs should be  
performed at least once a year. This maintenance schedule  
is based on normal usage. If you ride your bike more  
than average, or in rain, snow, or off road conditions,  
service your bicycle more often than the schedule sug-  
gests. If any part appears to be malfunctioning, inspect  
and service it immediately.  
Maintenance of Pro level hubs  
requires special tools, available as TCG

Special screw-  
driver  
Freehub seal installation tool  
Long bearing press  
Short bearing press  
Special screwdriver  
DT Swiss special freehub grease  
DT Swiss multi-purpose grease  
Spline tool  
Things to avoid  
Avoid high pressure washing systems, like those at most  
car washes. The high pressure can bypass bearing seals,
