Carbon frames and (full) carbon forks are lightweight construction components which are manufactured in several produc-tion steps using modern manufacturing procedures. The light weight is achieved mainly by using high-performance fibre composite materials in conjunction with an appropriate method of fibre construction. Component safety and rigidity, in additi-on to low mass were important criteria in the design of the carbon frames and forks. Unavoidable irregularities in the fibre ori-entation arising during manual procedures and small air inclusions in the resin coating layer or surface unevennesses are purely visual in nature and have no influence on the quality and performance of the frame.
Differences in finish and “blemishes” do not constitute grounds for complaint.
Irregularities of textile, like near-surface mi-nor air entrapments in the coating resin or unevenness of the surface, which cannot be avoided due to the process of manufacture and handcraft, are only of optical kind and do not have any effect on quality and per-formance of the frame. Differences in the finish and disfigurement are not a reason for any warranty claim.
Our carbon frames and (full) carbon forks are approved for a maximum rider and bike weight of 115 kg.
The Hybrid models with carbon frames are approved for a maximum rider and bike weight, depending on the specification, of 115 kg (Nuroad Hybrid C:62, Kathmandu Hybrid C:62),
135 kg (Stereo Hybrid HPC, AMS Hybrid C:68X) or 146 kg (Stereo Hybrid HPC).
A detailed overview can be found on our homepage in the FAQ´s. ( https://www.cube.eu/support/help-faq)
Maximum bike and rider weight =
Bicycle without additional load and add-on parts +
Body weight incl. clothing and baggage (e.g. back page)
Loadings deviating from the purpose of use intended (e.g. jumps) may lead to damage and constitute a risk to the user. We accept no liability for damage arising from improper use.
It is not permissible to fit additional components to any frame or fork tubing that is attached by means of clamping to the tubing in question.
Undefined stresses in the circumferential direction of the tubing can occur in this way which may cause damage that may drastically reduce the service life, and may also lead to a risk to the safety of the user.
Every frame including forks must be given a thorough examination at regular intervals for damage (e.g. cracks, visible delamination, discoloration, etc.).
Shock and impact stresses may cause damage not visible externally such as delaminations (separation of fibers from the surrounding plastic matrix) in the bottom laminate layers causing a drastic reduction in perfor-mance and consequently safety as well.
After any accident, crash, or other defined or uncontrolled mechanical stresses the frame and forks must not be ridden for reasons of safety and should be sent to us for examination (see also Chapter 6 Guarantee).
Concerning accessories used the instructions or use and user guide provided by the manufacturer concerned must be followed!

Manufacturing process

Twin Mold Technology

The Twin Mould technique uses reusable cores during the lay-up process to ensure precision frame molding.
Special inserts guarantee optimum ply orientation during the production process to add extra strength at frame points subject to higher loads.
This improves the safety of the product and delivers outstanding stiffness characteristics.

Advanced Twin Mold

This technique uses a complete core to provide the perfect frame form during the lay-up process. As with the Twin Mould technology, precise inserts are used to ensure extra strength at high-stress frame points.
This combination offers maximum control over fiber orientations during the lay-up and production process.
The Advanced Twin Mould high-tech carbon manufacturing process translates to outstanding product safety and quality to-gether with optimum weight and stiffness characteristics.

Use in competition

The danger of material damage!
Our frames are designed for extreme riding stresses. However, during use in com-petition stresses greater than those occurring during normal riding may arise as a result of collision with objects or other riders.
These stresses cannot possibly be foreseen and allowed for in the construction and design of a frame or forks. We therefore accept no liability for any damage resulting from use outside the intended purpose.
Frame and forks must be examined particularly carefully for damage (e.g. cracks, delamination, discoloration, etc.) before and after each instance of use in racing. After serious crashes or accidents, the frame and forks must not be ridden.
The surface of the frame and forks must not be damaged. This includes indentations and large deep scratches that penetrate beyond the first clear coat of lacquer. In case of doubt, the frame and forks must be sent in for checking.

How to use your carbon parts correctly

Risk of Personal Injury and Material Damage!

Do not, under any circumstances, mount brackets, screws, clamps, or other elements which exert mechanical pressure on the carbon tube.
Clamping onto bike stands or other wall brackets.
- Never clamp your bicycle around the carbon tube or carbon Seatpost in the clamping jaws of a bike stand.
- Please take care when using shackle locks! These may, under certain circumstances, cause damage to your frame.
When using shackle locks, please ensure that these only touch the respective carbon tube at the most, and are not exerting pressure.

Seat clamp/seat post

Risk of Personal Injury and Material Damage!
The prescribed tightening torque of the saddle clamp bolt is 5-6 Nm.
The seat tube must not be scoured or mechanically processed in any other way.
Please consult your authorized specialist retailer immediately after a fall.
The seat posts and seat tubes must not be lubricated. Only a carbon assembly paste may be used.
The seat clamp may not be closed if the seat post has been removed.

Front derailleur assembly

Risk of Personal Injury and Material Damage!
Racing bike frames are designed for either a braze-on socket derailleur mounting or for a classic derailleur clamp – MTB frames have either a classic derailleur clamp, Direct Mount, or an E-type derailleur fitting.
No other derailleur mountings may be used.
Maximum torque for fitting the derailleur clamp collar on the seat tube see. When fitting a torque wrench it is important to avoid deformation of the seat tube in the vicinity of the clamp.
Damage to the seat tube in the vicinity of the derailleur clamp by excessive tightening or incorrect size of the clamp collar may lead to safety-related deformation and damage and must be avoided.

Headset

Fully or semi-integrated headsets are used in carbon frames for optimum rigidity values and optimum distribution of forces and high levels of security.

Risk of Personal Injury and Material Damage!

Unauthorised milling work is not per-missible and will result in the guarantee being invalidated.
Delivery is with headset installed. Any change of headset must be agreed with the manufac-turing company. Press-fitting the headset shell bearings must be performed using a specially designed tool.
Press fitting must be performed with caution and it must be ensured that the shell bearings do not twist.
The shell bearings must not be greased at points where they are in contact with the frame. The side facing the bearing should be greased to ensure long life of the headset.

Bottom bracket/crank bearing system

The „Pressfit“ bottom bracket must be fitted using a tool specially designed for the task.
Only use bottom brackets or crank bottom bracket systems that are supported by the frame.
Special tools for assembly and disassembly of „Pressfit“ bearings are necessary.

Rear triangle

Your carbon frame rear assembly has been designed and built for a hub width of 142 mm (road/gravel/trekking bike) or 148 mm (MTB Hardtail and MTB-Fully).
Risk of Personal Injury and Material Damage!
On the rear triangle, only hubs with an installation width of 142 mm (road/gravel / trekking bike) or 148 mm (MTB-Hardtail / MTB-Fully) that are suitable for 12 mm thru-axles can be fitted.
The use of hubs with other dimensions and/or without a quick-release mechanism may result in stress and distension conditions, which can lead to serious damage and therefore present a safety risk.
The rear assembly is designed.
The rear triangle is designed for standard road racing brakes or disc brakes. The maximum permissible torque of the brake fastening can be found on.
The maximum permissible rear wheel disc brake size amounts to PHENIX, REACTION and AMS ZERO99 160 mm, AMS ONE11 / HYBRID ONE44 and STEREO ONE22-77 180 mm, TWO15 and STEREO HYBRID ONE 44-77 203 mm.

Rear derailleur assembly

The maximum torque for fitting the rear derailleur to a hanger.
For SRAM Eagle Transmission rear derailleurs, observe the manufacturer‘s specifications for the prescribed tightening torque.

Bottle cage inserts

The threaded inserts on your carbon frame are designed for fixing standard bottle cages with an M5 thread. Other thread sizes are impermissible.
The maximum torque of bottle holder fixing screws you will find on.
Carbon frames are approved for bottle holders which can take a 750 ml capacity bottle.
Hybrid models can also accommodate the Bosch PowerMore 250 on the bottle cage in-serts, if approved.

Risk of Personal Injury and Material Damage!
If you do not observe the following instructions this can result in falls, accidents, and property damage.
Further information can be found in our Service FAQ at https://www.cube.eu/support/help-faq
Your CUBE bike is generally approved for use with a indoor trainer, all pedelec models (hybrid are excluded from this.
Please ensure that your bike is compatible with the trainer, furthermore, the installation instructions of the respective trainer manufacturer must be observed.

Transport

Your carbon frame is a high-performance lightweight product.
Risk of Personal Injury and Material Damage!
When traveling by air or on journeys where the “bicycle“ luggage item is not checked concerning damage-free stowage, adequate protection of the frame and forks must be ensured (e.g. by using suitable hard-top cases, etc.)
When transporting with the front or rear wheel removed it is recommended that a distance piece is inserted instead of the hub in the rear assembly (142 mm road/gravel / trekking bike, 48 mm MTB-Fully, MTB-Hardtail) and in the (full) carbon forks (100 mm) to prevent damage.
Due care must be taken when transporting bicycles with carbon frames.
The frame should particularly be protected against contact with other parts using a cover for example.
Transporting your carbon frame with carrier systems which use clamping elements for fixing and retaining the frame tubes is impermissible as the clamping forces of the fixing elements can cause damage to the frame / forks tubing
During transportation do not place any objects on the frame and forks and stow so that they cannot slip.
During transportation do not place any objects on the frame and forks and stow so that they cannot slip.
Please ensure that the bicycle is in a fixed and stable position during transport.

(Full-) carbon forks

Our full carbon forks and carbon forks with aluminum steerer have a shaft diameter of 1 1/8” in the clamp area of one of the stems.
Near the lower bearing race, the forks fit the following headset sizes; 1 1/8”, 1 ¼”, or 1 ½”.
Only headsets and stems that are designed or approved according to the frame and fork specification by the bike manufacturer may be used.

Risk of Personal Injury and Material Damage!

If the headset bearing lower cone ring is driven into the bearing seat with massive force there is a danger of damaging the forks.
Fitting a headset must be carried out by specialist technicians.
The shaft tube external diameter in the vicinity of the stem is designed for front extensions with a clamp diameter of 1 1/8”.
Only the handlebar stems with corresponding internal dimensions and cleanly finished interior surfaces may be used.
The fitted stem may project no more than a maximum of 2 mm above the edge of the shaft tube end.
The front brake is fitted to the fork using special screws supplied by the manufacturer.
The tightening torque of the screws can be found in the illustration on.

Risk of Personal Injury and Material Damage!

Carbon forks with a steerer made of alu-minium may be assembled with a so-called “star-nut” to adjust the headset. When doing this the fork should not be assembled on a hard surface in order not to damage the fork.
In this case, the provided so-called “expander” or “thread insert “ must be used on a full carbon fork. The use of a so-called “star-nut” on a full carbon fork will lead to serious damage to the steerer tube or dangerous failure of the fork.
The length of the steerer tube can only be cut to size by a professional bicycle mechanic.
Ideally, a metal saw with a low abrasion rate or a metal circular saw with diamond saw blades and water cooling should be used.
In the event of dry trimming, adequate protection from dust inhalation produced should be ensured. Inhalation protection with a fine dust filter and safety glasses are recommended.

Care instructions

Your carbon frame and your (full) car-bon forks should be cleaned regularly. Ordinary paint care products with or without silicon additive and cold to lu-kewarm water to which may be added ordinary detergent may be used.
To be avoided are solvents of any description, alcohols (e. g. ethanol or isopropanol), hot water with alkaline additives or cleaning with steam jets and pressure washers.

Guarantee and special ex gratia settlements

Services under the guarantee are provided only in the event of faulty materials or manufacture and never in the event of fatigue or overload stress damage.
We provide 3 years guarantee on our frames and forks and we also offer special ex gratia services.

Risk of Personal Injury and Material Damage!

If you discover damage to your frame and/or forks you may send the damaged frame and/or forks to us for assessment and an estima-te of possible repair costs via your dealer.
Transport costs in every case are borne by the customer. Following assessment of repair costs the repair is carried out either free of charge or you will receive an advance estimate of repair costs.
