The brake pads and discs on a new bike are new themselves and don't work to their full potential.
You can avoid the risk of the inner tubes on your mountain bike getting punctured or pinched by switching to TUBELESS. To do this you'll need to buy the following: -Sealant: DECATHLON: TUBELESS READY TYRE AND WHEEL SEALANT (8550735) STEPS TO FOLLOW:
When you take your new bike out for a ride for the first time, a lot of parts move around and fall into place.
It's a sad fact of cycling that everyone gets punctures. - The terrain (thorns, bramble bushes, glass, nails, etc)
There are one or two things you can do to make your fork "softer": 1. Do some basic maintenance: using a simple oil can. Squirt some oil on the pivots of the fork and move it around to work the oil into the blades.
There could be several reasons why your gears (cogs) are not shifting correctly.
The lever is spongy and/or touches the handlebars before you can brake:
A twisted dropout causes the derailleur to become misaligned, preventing it from doing its job correctly. Look at your bike from behind and check to see if the derailleur is straight.
So you've broken your chain.You've got two options: 1. Repair it yourself with the help of this video. You'll need a chain tool and a quick-release link. 2. Drop in at one of our DECATHLON workshops and have it done by one of our technicians.
These videos show you how to repair your bike and replace parts yourself. Our YouTube channel has a lot more content. Have a good look around.

To clean your bike properly, you'll need some bike cleaner, a sponge and a brush. Spray the bike with a hose before applying the cleaning products. Use the sponge and brush to apply the products. Allow the product to act before rinsing the bike. Rinse it from a distance to avoid damaging mechanical parts. Finally, dry the bike with a soft, clean, dry cloth.
To clean and lubricate your drive train, you will need a degreaser spray, a soft bristled brush and a lubricant. The first step involves covering the brake disc with a clean cloth to prevent any lubricant from getting on to it. Then apply the degreaser to the whole of the drive train and scrub the cassette, chain and derailleur jockey wheels with the brush. Leave to act for a few minutes before rinsing the degreaser off from a suitable distance. Allow the drive train to dry before applying the lubricant. Shake the lubricant and apply to the inside of the chain, where it will work best.
Is your drive train cable dirty, rusty or damaged or are your gear changes stiff, random or not as slick as they should be? If so, the cable needs changing. You'll need a pair of pliers, a screwdriver, cable cutters, an Allen key and a new derailleur cables and housings kit. Start by removing the cable from the housing. Remove the hood from the gear shifter, move the indicator to the last gear and cut the cable. This will allow you to remove all of the cable and then the housing. Cut the housing to size and fit the end caps on the end of the cable, which is now ready to fit. Thread the cable through the shifter and push it through the housing. Then put the hood back on the shifter and attach the cable to the derailleur. To adjust the drive train, tighten the cable if the gears do not shift up easily and slacken it if they do not shift down smoothly. Finally, cut the cable and use the pliers to attach the end cap to it.
Removing and fitting a wheel when your bike has a derailleur cage lock is a pretty tricky operation. Put the chain on the last cog and unlock the derailleur cage. To remove the wheel, just open the quick-release lock. To fit it back on, put the chain on the last cog, close the quick-release lock, and lock the derailleur cage to prevent the chain from jumping.
You need the following to repair a puncture: a pump, a basin of water, a cloth and an inner tube kit. Put a little pressure on the inner tube. To find the puncture, submerge the inner tube in the basin of water. Once you've spotted it, dry the inner tube with a cloth and scrape the area around it with the sandpaper provided in the kit. Scraping the inner tube will allow the glue to adhere better. Apply the glue generously around the hole and wait for three to five minutes. Place the patch over the hole and hold it there for a few minutes. You can then fit your inner tube back into the tyre.
You will need the following: new brake pads, a flat screwdriver and a 3mm Allen key. Remove the wheel first of all. Then use the screwdriver to move the pads apart and put the pistons back into their original position. Take out the pin holding the pads in place and remove them from their housings.Position the counter spring between the new pads. Insert the new pads in the brake caliper and then put the pin back in place to complete the process. Put the wheel back on and check to make sure that the brake pads are properly in place and do not rub against the disc.
You will need a 5mm Allen key. Unscrew the brake caliper, spin the wheel and operate the brake lever. It is important to keep the brake lever engaged before screwing the caliper back in place. Check to see that the disc and the pads are still in contact.
You will need a new derailleur dropout that fits your bike (check the "SPARE PARTS" section) and a 5mm Allen key. Take off the wheel and the damaged derailleur dropout. Position the new dropout on the frame. Remove the old dropout part from the derailleur before fitting the new one with the Allen key. Fit the derailleur on to the new dropout and check the gears.
You will need the following: a chain tool, a new chain and a quick-release link. Put the chain on the cog and on the smallest chainwheel. Remove the quick-release link using quick-release chain tool and then remove the chain from the drive train. Put the new chain on the last of the cogs and on the smallest chainwheel. This makes it easier to determine its optimal length. The chain should pass close to the top pulley of the upper jockey wheel on the derailleur. Once you've determined the length of the chain, use the chain tool to cut it as required. Then fit the quick-release link on the chain and turn the pedal to position the quick-release lever on the top part of the chain. Press it with your hand to check that it is on the right position.
