This bike is designed for training and competing in cross-country marathon mountain bike races. Dig deep and take on the whole field! Its all-new full suspension carbon/aluminium 29" frame will boost your performance",while its 120mm suspension will help you get to the finish line quicker in marathon and long-distance events.
The brake pads and discs on a new bike are new themselves and don't work to their full potential.
To reduce the risk of your inner tube being punctured or pinched, you may want to consider making the wheels on your MTB "Tubeless". To do this, you will need to buy: - Puncture prevention liquid (tyre sealant): DECATHLON: TYRE SEALANT FOR TUBELESS READY TYRES AND RIMS (item 8550735) STEPS TO TAKE:
The first time you ride your brand new bike, it's normal that many of its components will move about slightly and settle into their proper places.
Unfortunately, anyone can get a puncture. - The ground (thorns, brambles, glass, nails, etc.)
There are a couple of things you can do to "soften" your fork: 1- Perform a basic maintenance operation: you can regularly care for your fork with a small oil can. Simply put a few drops of oil on the fork pivots and work the fork to help the oil penetrate into the blades.
There could be several reasons the chain isn't shifting properly between cogs on the rear cassette:
4. To adjust your SRAM derailleur, use the SRAM DERAILLEUR ADJUSTMENT TOOL. This indispensable tool allows you to adjust the distance between the upper roller and the cassette.
5. Also check that the derailleur hanger is not bent. If it is, refer to the "YOUR DERAILLEUR HANGER IS BENT" section
PS: If you regularly ride your MTB in wet or muddy conditions, or if you regularly wash your bike with lots of water, then your cables and cable housing will need to be replaced more frequently. Washing your bike using a high pressure hose is highly discouraged as it can push dirt and dust into the cable housing.
The first thing to do when replacing a derailleur cable in a bike with carbon frames is to take the derailleur apart. All you will need to do this is an Allen key. The old cable will act as a guide when passing the liner through. The liner is a sort of temporary internal casing that makes it easier to push the cable correctly through the frame. Once you have removed the cable from the derailleur, you then need to thread the liner along it until it comes out of the frame, at the point where the cable is pushed in. Take care to slide the liner around the cable, without it PUSHING it. You can remove the derailleur cable when the liner is in place. The cable now has a clear path to follow inside the frame. It will be easier to insert the cable and to pull it out through the cable exit point. You can remove the liner once you have pushed the cable all the way through it.
The lever is spongy and/or touches the handlebars before you can brake:
A bent hanger causes the derailleur to be out of alignment and therefore unable to function correctly. Stand behind your bike and examine the alignment of the derailleur.
Have you broken your chain? You've got 2 options: 1- Repair it yourself with the help of this video. You're going to need a chain tool and a quick link. 2- Visit one of our Decathlon workshops to get our technicians to repair it.

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 gear cable dirty, rusty or damaged, or are your gears hard to shift or shifting randomly? Then your gear cable needs to be changed! To do this, you'll need some pliers, a screwdriver, a cable cutter, an Allen key and a new set of cables and housing. First of all, you'll need to remove the cable from its housing. Start by removing the plug from the shifter. Shift the gears all the way down, then cut the cable so you can pull it all the way out of the housing. Next, hold the housing against your bike to work out how long it needs to be. Cut it and place the end caps on. You can now install the housing. Pass the cable through the shifter and feed it through the housing. Next, screw the plug back in and fix the cable to the derailleur. Adjust the drivetrain by tightening the cable if the gears are struggling to shift up and slackening it if they are struggling to shift down. Once you're done, cut the cable and use the pliers to crimp the end cap onto it.
Removing and installing a wheel if your bike is equipped with a derailleur cage plate lock can be a tricky operation. First, put the chain on the smallest cog, then unlock the derailleur cage plate. To remove the wheel, simply open the quick release without changing its adjustment. To put the wheel back on, insert the wheel, place the chain on the smallest cog, tighten the quick release, and lock the derailleur cage plate to keep 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 chainring. Remove the quick-release link using a 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 chainring. 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.
