Intended use
Any use differing from that intended could cause an accident and result in death or
serious injury.
THM-Clavicula crank systems have been exclusively designed
- for installation on standard racing cycles, time trial and gravel.
- for the permitted area ofapplication – see Areaofapplication , page 12
Fundamental safety precautions
The following warnings for the THM-Clavicula component apply to all Clavicula models
(Clavicula SE, Clavicula XC etc.), unless otherwise specified.
Forthe time being we limit the service life of your THM-Clavicula crank system to 100,000 km
or 10 years. It is mandatory for you to contact us before continuing to use your THM-Clavicula
crank system after one of these limits has expired!
Always remember that riding a bicycle involves potential danger for the rider and other road
users, as well as for the bicycle and its components. Even if protective equipment and safety
devices are used, accidents resulting in death or serious injury can still occur.
You should therefore use your common sense and avoid any unreasonable
behavior!

Assembly & Maintenance
Risk of accident caused by assembly and maintenance work which has not been
conducted in a professional manner.
- Do not overestimate your technical ability. All assembly and maintenance work
should be performed by a specialist workshop for bicycles. This is the only way to
ensure the work is conducted in a professional manner.
- Always stick toall the specified tightening torques for the screw connections.
- Only use suitable, undamaged, high-quality tools.
- Only ever use original THM components which are available from your specialist
dealer or directly from THM.
- Never modify your THM components on your own.
- Check your crank system (incl. crankarms, bottom bracket, chainrings) to make
sure it is undamaged and working properly before every ride. Send your THM-
Clavicula component in for review before further use if damage is visible (cracks,
fractures, deformations, etc.) or if you are in any doubt about itsfunctionality.
- Check your THM components before each ride to ensure the surfaces are
completely undamaged. Send your THM components in for inspection before
further use if damage is visible (deep scratches inthe paintwork which extend into
the carbon structure, large abrasions, etc.), if you are in any doubt about their
functionality or if the Clavicula lettering is abraded at one or more points (wear
indicator).
- Always ensure your bicycle is well maintained and in a flawless condition. Care
and maintenance will prolong the service life of your bicycle and its components
and improve your personal safety.

SAFETY
On the road
Danger of accidents due to improper behavior or improper equipment during riding.
- Always ride with foresight, attention and a readiness to brake.
- Adjust your speed to the prevailing conditions (traffic, weather, visibility, etc.).
- Do not use your THM components at ambient temperatures below -10°C (14°F).
- Do not exceed the maximum overall weight for which your THM
components have been approved – see Dimensions, page 9.
- Always comply with the traffic regulations that are in force in the country
where you are using your bicycle.
- When riding your bicycle, you should always wear a high-quality cycling
helmet (e.g. ANSI certified) that isin excellent condition. Yourclothing should
beclose-fitting butnot restrictive.
- Only ride your bicycle ifyou are in good physical condition and your
bicycle and all its components are operating in a flawless manner.
- If you are involved in a heavy fall, you should not continue to ride your
bicycle. If such a case occurs, send us your THM components for inspection,
even if no external damage is visible! In your own interest you should treat
all the components on your bicycle which have been produced by other
manufacturers in the same manner.
Transport & Storage
Risk of accident caused by damaged bicycle components.
- Always transport your bicycle in an appropriate and careful manner.
- Do not store your THM components at an ambient temperature below
-15°C (5°F) or above 55°C (131°F).
Risk of accident.
- Do not allow children to play with your bicycle.

General Information
If not properly executed, assembly and maintenance work could cause accidents
resulting in serious or fatal injury.
- Do not overestimate your technical ability. All assembly and maintenance
work should be performed by a specialist workshop for bicycles. This is the
only way to ensure the work is conducted in a professional manner.
Preparing the Frame
It is mandatory for you to read and follow the safety and assembly instructions
provided by the manufacturer of your frame.
Secure your bicycle in an appropriate assembly stand.
If necessary, remove the crankset and the old
bottom bracket.
If necessary, use cleaning solvent or other similar
agents to clean the bottom bracket housing of your
frame.
Make sure that the outer faces of the bottom bracket
housing are plane, parallel, milled to the correct
dimension and free of burrs – page 10.
If necessary, rework the bottom bracket housing
using an appropriate milling tool (Cyclus, ParkTool®
or another similar tool).
Make sure that the threads of the bottom
bracket housing are clean, free from paint
residues and adequately tapped into the
housing.
If necessary, rework the threads with an appropriate
cutting tool (Cyclus, ParkTool® or another similar
tool).

Installation of the chainrings
The Clavicula XC is designed for a single chainring setup. The spider has 4 holes in a 104 mm
diameter. To carry the load of the screws and to protect the carbon surface we strongly
recommend placing some special washers between the crankset and the screw (see below)
Danger of damage to the chainring mount.
- The number of chainwheel teeth must never be less than the minimum number
required – see page 10.
- Always observe the tightening torques specified by the manufacturer of the
chain ring bolts; however, do not exceed a max. tightening torque of 6 N·m
(53 lbf·in) under any circumstances.
Install 1 chainring
- Place the chainring nut (1)

Mounting the crankset
Before mounting the crankset, please check if the bottom bracket is correctly installed and runs
smoothly. For BSA MTB 73, Shimano PF 92 and PF30, please check if the sealing is mounted. This
description is only valid if you use THM bottom bracket which are designed for the THM cranksets.
If you use non THM bearings, please check if the width (see Specifications) of the
bearings allows for the cone sleeve to be installed in the correct position as described
in this chapter.
- Locate the spacer (4) required for
your bottom brackt on the cone sleeve
(3). (See p. 10 ff).
- Press the cone sleeve in the bearing
on the non-drive side (left).
- Place the spacer (6) required for
your bottom brackt onto the axle.
(See p. 10 ff).
- Lightly grease the bearing seat of the
axle.
- Insert the axle oftherightcrank through
the bottom bracket up to its stop.
- Thoroughly degrease the axle and
crank multi-tooth segment.
- Make sure that the clamping screw (2)
is loosened or removed.
- Fit the left crank arm to the multi-
tooth segment of the axle.
- Press the cranks together by hand as
far as possible. Both cranks abut
against the spacer rings.

- Screw the adjusting screw (1) into the
axle –use the THM adjustment tool, or
a 6 mm Allen key for this.
tighten = screw counterclockwise!
loosen = screw clockwise!
- Tighten the adjusting screw until the
collar on the cone sleeve is flush
against the bearing or spacer ring.
The tightening torque required for
this is typically 5–10 Nm (44–
106lbf·in) –depending on the actual
width of the bottom bracket housing.
- Check the clearance between the
cranks, chainrings and the chain
stays of the frame.
- Minimum clearance: 3mm.
- Remove the adjusting screw (1) .
- Pull the crank arm a little off the
axle (3-5 mm).
- Check if the cone sleeve (black) is
flush with the end of the multi
segment area (green marked line) or
up to 1.5 mm more towards the
chainring side of the crankset.
- If the cone sleeve is not in the
position described above this can
lead to premature wear.
