Roller chains are essential for effective power transfer and smooth mechanical performance of the Kuberg bikes. The Kuberb bikes use lighter weight higher performance chains, which gives you an edge when riding. You need to know that without routine maintenance, these chains will degrade, necessitating expensive repairs and downtime. This article offers crucial maintenance advice to maintain your roller chain's top performance, reduce downtime, and increase time on the trail.
Typical Roller Chain Problems
Roller chains are used all over the place because they are resilient and do their job well, but if they are not properly maintained, they are vulnerable to wear and damage. Typical issues include chain elongation, corrosion, and increasing noise levels during operation. In addition to impairing chain performance, neglected maintenance also causes early failure, which will ruin a great ride.
Continual inspection and lubrication
- Inspection Methods
Visual inspections should be carried out on a frequent basis, we recommend examinging the chain before every ride (at least every other ride) to guarantee peak performance. It only takes a moment, and will prevent a lot of trouble. Examine the components for wear indicators such as elongation, bent or broken links, and excessive sprocket wear. Chain elongation must be measured accurately since it might point to a need for replacement or correction.
To check if a roller chain is elongated:
Measure the pitch (distance between roller centers).
Compare it to the manufacturer's original specifications.
Calculate percentage elongation.
Look for visible signs of wear.
If it's elongated:
Replace the chain with a new one.
Inspect and replace worn sprockets.
Maintain proper lubrication and tension.
Use high-quality chains for longevity.
- Proper Lubrication Techniques
It's important to pick the correct kind of lubricant since various circumstances call for different formulas. When choosing a lubricant, keep things like temperature, humidity, and exposure to corrosive chemicals in mind. On a dirt bike, the chain should be lubricated every 500-1000 miles, depending on your riding habits and riding environment. This will ensure peak performance and sustainability for your bike.
To guarantee optimal chain protection, Normally every 100-150 miles or once a week if you are riding most days on pavement in dry conditions. If you are riding mostly in dry conditions on pavement, you probably don't need to clean your chain every time you lube it. In addition, it is important to keep the lubricant clean to prevent corrosion wear, and damage caused by contamination. The primary purpose of chain lube is to lubricate the rollers and other internal parts of each link, not to lubricate the outside. Excess lube on the outside of the chain will get dirt stuck to it, that dirt will slowly work its way into the rollers that you're trying to protect, and dirt inside will grind away at the internal parts and wear out the chain faster.
Tensioning the Roller Chain
A. The Value of Appropriate Tension
The roller chain must be kept at the proper tension for effective power transmission. An excessive amount of chain slack can cause the chain to leap off the sprocket teeth, which might cause damage and a loss of power. On the other hand, a chain that is too tight might result in greater wear, higher energy expenditure, and early failure.
Follow these steps to adjust the chain tension:
- Ensure the power is turned off.
- Remove the chain tensioner by removing the mount bolt.
- Loosen the axle nuts and band brake mount bolt.
- Turn the adjustment nuts evenly on both sides. Very small movements make a big difference. Do not tighten so much that there is no slack at all. It should be ‘taught’, not ‘tight.’
- While the chain guard is off, lubricate the chain & check the sprocket bolts for tightness.
- Repeat the above procedure, ensuring all bolts are tight.
- Check the wheel for alignment and the chain for tension.
B. Techniques for Tensioning
Tools like tensioners and adjusters are useful for getting the right chain tension. Make sure these components are operating correctly by performing regular inspections. Chain tension must be properly adjusted to avoid slippage and excessive wear. To choose the right tensioning method for your particular application, look for manufacturer specifications or speak with professionals.
Repairing and Replacing Roller Chains
A . Assessing Chain Damage
Chain wear indicators must be found during routine inspections. Watch out for elongation, obvious wear patterns, cracked, or broken links. Analyze the extent of the damage to decide if replacement or repair is required, please click on the link to watch the video for a better understanding: Chain Wear Indicators
B. Repair Procedures
In cases of minor damage, the chain's functioning can be recovered by swapping out broken links or roller pins. Use specialist chain repair equipment to guarantee proper installation and alignment.
C. Making Sure the Chain Is Replaced Correctly
When changing a roller chain, it is essential to comprehend the chain size and pitch. To verify compatibility, see the manufacturer's specs or get help from an expert. To avoid early failure and improve chain performance, follow correct installation techniques.
Here are some roller chains from Kuberg:

Kuberg Ranger Secondary: ASE-DHS012-1
Kuberg Freerider bigger wheels: ASE-FR0066-4
Kuberg Freerider Small wheels: ASE-FR0066
How to Store Roller Chains Correctly
Getting Chains Ready for Storage
Roller chains should be completely cleaned and dried before being stored to avoid corrosion. To further preserve the chain while being stored, use a protective material like a rust inhibitor. In order to prevent contamination or damage, roller chains should be stored under the proper circumstances, such as in a clean, dry atmosphere. Avoiding unexpected impacts or improper handling when recovering chains is important to avoid chain distortion and subsequent operational issues.
Summary and Important Learnings
In order to maintain your roller chain and keep it performing at its best, regular maintenance is essential. Perform load testing, precise chain elongation measurement, and visual inspections. Ensure the tension is correct, lubrication is appropriate, and take precautions to avoid contamination. Chains that are damaged should be stored appropriately to avoid corrosion and repaired or replaced as necessary. Implement preventative maintenance programs and train staff on correct handling to extend roller chain lifespan.
