Wheels and axles
WARNING: Your bike is delivered pre-assembled with inner tubes for transportation
and display.
Always setup the wheels following the recommendations and instructions of the
wheels and the tire manufacturers:
• Some wheels must only be assembled in tubeless
• Some wheels must only be installed with specific tires for a tubeless setup
(hookless rims)
• Even if the wheels are tubeless, some tires assembled on some bike models may
not be tubeless
• Please read carefully the tires and the wheels instructions.
WARNING: Make sure the tubeless compatibility is insured between your wheels
and your tires:
• Minimum and maximum tire size
• Minimum and maximum tire pressure
• Tire bead design (hooked or hookless)
• Rim design (hooked or hookless)
• Grease the thread and the head of the thru-axles.
Push in
Grease
6 10 Nm
• Through axles have to be torqued to 10 Nm using a hex 6mm.
• Once installed, you can plug the rubber aero caps into the fork and the rear dropout.
Service instructions
The BMC Speedmachine is a high-tech, performance oriented product. We ask you
to specially take care of your bike if you want it to deliver the maximum of it’s perfor-
mance over the years.
If you notice parts that are worn out or damaged, do not hesitate to replace the part
and or contact your BMC dealer.
Washing your bike
You should never use high pressure washing device to clean your Speedmachine.
The integrated components of the bike were designed to be integrated and aerody-
namically efficient, they were not designed to be water-tight at high pressure.
We recommend to use a brush and soft bike soap, and rinse with water at low pres-
sure.
Avoid degreaser and brake cleaners directly on the frame, fork and base bar. Compos-
ite carbon and painted components could be permanently damaged and fragilized.
After washing
If there is water trapped in your frame, it should drain automatically from below the
bottom bracket.
If the steering does not rotate freely, check the installation of the base bar. If the issue
is not solved, it may be that your headset bearings need to be replaced.
If your seatpost makes unusual noise after washing or riding in wet weather, you need
to take the seatpost apart, clean the frame seat tube and the seatpost, and reapply
carbon friction paste between frame and seatpost.
Trouble shooting
Noise from the saddle or the seatpost:
• Apply friction paste between the seatpost and the frame seat tube.
• Apply grease on each element of the saddle clamp (bolt, washer, clamps).
• Apply friction paste between the seatpost shaft and the frame.
Noise from the drivetrain:
• Check front and rear derailleur assembly and front and rear dropout hangers assem-
bly. Reapply thread locker compound on the dropout hanger bolts if necessary and
tighten to torque.
• Check rear thru axle: clean with a degreaser, reapply grease on thru axle like indicat-
ed in this manual and reassemble tightening to torque.
• Check bottom bracket and crankset following instructions from their manufacturer(s).
Seatpost slipping down:
• Apply friction paste between the seatpost and the frame seat tube
• Control the torque at the seatpost clamp and at the saddle clamp.
Play in the headset:
• Remove the base bar, and tighten lightly the headset bolt to 4Nm.
Friction in the headset:
• Make sure nothing is stuck in between head tube and fork or between the base bar
and the head tube.
• Control the headset bearings and replace them if necessary.
Play in the extensions or base bar:
• Do not ride with play in the cockpit assembly.
• Control the torque settings of every single bolt.
• Apply grease, thread lock and friction paste as indicated in this manual.
• Control that none of the stem bolt is damaged.
