Helpful Guide To Carbon Bicycle Frame Repair And Care

By Minnie Whitley


While a carbon fiber frame was once only seen in very costly road bikes, today it's commonly used by many manufacturers for building quality cycles. Although previously thought to be more likely to suffer impact damage, modern advancements have mostly overcome this problem. It is advisable though, for owners of these bikes to be aware of the care they need and be familiar with carbon bicycle repair indications.

Even though as an element carbon is fairly durable, it's still prone to fatigue over time as its epoxy resin softens. The more often and heavy the use of the bike, the sooner this deterioration will occur. Other factors which influence the longevity of the bike include nature of the riding it is used for, level of care it receives, tube thickness, and structural design.

Carbonized frames tend to be inert or unreactive by nature so they will not produce a chemical reaction such as corrosion or salt damage with most types of cleaners. However, the whole frame is not made from this same material, many parts are aluminum which is prone to rusting when exposed to harsh solvents, so care still must be taken when cleaning the bike.

Any kind of bike can be subject to errors in manufacturing, resulting in minor flaws. The most common issues with carbon frame bikes are either bent dropouts or broken drink bottle cage lugs, but these are not serious and are normally easily repaired under the warranty. Scrapes on the surface are usually nothing more than an aesthetic concern, but if a crack is detected in the carbon matrix, this does require timely attention.

A weak spot can spell disaster unless it is dealt with early on, it can result in issues such as bent rear derailleur hangers, a cracked seat or seat post, or even a break in the frame. Not all serious frame damage is apparent to the untrained eye, which is why it is risky to buy used bikes of this kind.

A bike that has experienced a serious crash but is still seemingly salvageable should be evaluated by a bicycle mechanic. These pros know how to recognize areas that have endured major stress and use equipment such as UV or ultrasound scanners to pinpoint internal damage. Regular servicing every six months or so is recommended, and if any strange noises are noted, these should be brought to the mechanic's attention.

Fortunately, most damage can be repaired, but it is essential that bigger issues only be dealt with by those who specialize in carbon frame repairs. A simple fix on the bike's exterior should be fine if done at any bike shop, but if the frame's integrity has been compromised an expert's knowledge will be necessary.

In some cases replacing damaged parts is more sensible than fixing them. If it is less expensive and will take less time to order and install new parts than to repair damaged existing ones, this is the best choice. This depends on the extent and location of the damage.
