Rock dust, mud and other dirt are all part of the reality of a gravel bike outing. To keep your outings running smoothly, it's essential to maintain the mechanics of your precious bike. To answer the most frequently asked questions about gravel bike maintenance, we've joined forces with the real specialists: our Mint'N Dry partners.

1. What lubrication should I use for my bicycle chain?

Two types of lubricant are recommended, depending on conditions. The first, dry formula lubricant, is optimal when gravel roads are dry and dusty. It prevents dirt build-up for smooth pedaling. The second, the all-conditions lubricant, is ultra-versatile, performing equally well in both dry and wet conditions, for example if it rains during a ride. This formula also protects the chain from the oxidation and corrosion that can occur after rain. 

The major advantage of the Mint'N Dry range of lubricants is that the products are biodegradable and enriched with ceramic particles, which minimize chain wear by acting as antifriction protection. What's more, the ceramic optimizes performance at full throttle, delivering a much smoother pedaling action. This lubricant is also highly durable on the chain. 

2. Is it necessary to wipe the chain after applying lubricant?

Yes, the chain can be wiped with a microfiber cloth. However, the mistake that is often made is to wipe too much, which dries out the chain, when what you really want is to lubricate it! We therefore recommend wiping lightly, pinching the sides of the chain. 

3. How often should I lubricate my bicycle chain?

On a gravel bike, it's advisable to apply lubricant almost every time you ride, whether it's dry or designed for all conditions. The frequency depends mainly on the distance covered and the conditions encountered. In dry weather, dust tends to remove lubricant more quickly, while in wet conditions, wear is often less, except in the case of heavy downpours. When in doubt, it's best to lubricate: a poorly maintained chain is not only unpleasant to ride, it can also damage the transmission.

4. How often should a bicycle chain be degreased?

There's no particular recommendation, but it's important to clean the chain and derailleur with a degreaser when the ride has been particularly muddy, or after several rides in dry conditions. You'll feel (and hear!) that the chain needs a more thorough cleaning. Cleaning with a degreaser prevents breakage or premature wear of components. 

5. How do I know if my chain is worn and when to replace it?

The wear indicator is an interesting tool to have if you ride several kilometers a year. It lets you know if the chain is showing signs of link elongation. Also, keep an eye out for rust on the chain, which can also be a sign of wear. During your seasonal maintenance at your favorite specialist store, have the chain checked to see if it needs changing. 

6. How do I wash my bike after a muddy or dusty outing?

Home cleaning involves a few steps. Sit outside quietly and make a ritual of it. With your favorite after-bike drink in hand, follow these simple steps:

  • Rinse the bike with large jets of water
  • Spray Mint'N Dry degreaser on derailleur and chain
  • Use a suitable brush to scrub and clean the derailleur and chain. There are also chain-cleaning tools that work really well.
  • Rinse and repeat if necessary.
  • Spray Mint'N Dry mud cleaning soap on bike frame and tires
  • Clean the frame with a microfiber cloth. For tires, use a suitable brush to scrub them thoroughly.
  • Rinse with large jets of water
  • Dry frame and components with a clean, dry cloth
  • Lubricate the chain

Mint'N Dry has created a no-rinse cleaner formula that's easy to use and ideal for not having to use the garden hose. It's effective when dirt build-up is minimal and without too much sludge.

7. Which products are recommended (degreaser, lubricant, cleaner)?

Bicycle cleaning products are designed for this type of maintenance. Your maintenance kit should therefore include degreaser, cleaning soap, lubricant, brushes and microfiber cloths. 

8. How do I maintain a bicycle derailleur?

The derailleur also needs a degreasing once in a while. Take a look at it after your rides, especially when conditions are very wet. A lot of debris can get lodged in it, and mud often sticks to it. The use of a degreaser is recommended to remove dirt from the derailleur. The derailleur can be scrubbed with a suitable brush and then rinsed with a large jet of water. 

9. Do I need to check my tire pressure before each outing?

Of course you can! This simple gesture can prevent you from having to stop along the way. Get into the habit of checking that everything's working properly on your bike before a ride: tire pressure, wheel axles, brakes, chain and derailleur.

10. What is the correct pressure for gravel tires?

The recommended pressure depends on the type of tire and its width. The wider the tire, the lower the recommended pressure. Maximum and minimum pressures are usually marked on the tire sidewall. In addition, you need to take the terrain into account: if you ride mainly on roads, the pressure will not be the same as if you ride on singletrack. The rider's weight also influences the pressure to be added. Generally speaking:

  • 35 to 38 mm tires: 40-55 psi
  • 40 to 45 mm tires: 30-50 psi
  • 45 to 50 mm tires: 25-40 psi

11. How often should a complete service be carried out in a specialist store? 

A full service at a specialist workshop should be carried out before the start of the season and at the end of the season. As you ride, be on the lookout for any noises, creaks or sensations that might indicate that a visit to the workshop is in order. Remember that workshop technicians are the specialists in bicycle mechanics. They are your best allies in caring for your bike and advising you.
