VAN RYSEL RCX 2 SHIMANO GRX 12S

Q: Essential tools for your workshop.

To service your RCX correctly, you need to have the right tools.

Q: Selecting the right tyre for your RCX

The tyre is the only element in contact with the ground. To minimise the risk of it losing grip, it's essential to choose the right type of tyre, and adapt the pressure accordingly.The RCX comes with tubeless-ready wheels.

Q: Adjusting and tightening the seatpost

To make sure your saddle is set correctly, you must make sure it is properly tightened. A loose seatpost can easily drop down when you're out and about on your bike. If you tighten it up too much, however, you run the risk of crushing the seatpost and damaging your bike. The best way to tighten a seatpost is to use a torque wrench. It should be tightened to 6 Nm. NB: Do not exceed the maximum height indicated on the seat post.

Q: Changing your chain

The chain is a vital part of your bike's drive train. The following are tell-tale signs that you need to change it:- The chain starts jumping.- The chain has been on for more than 5,000 kilometres.- Gear changes are not smooth.To find out more read our article:

Q: Changing your brake pads

The following are all signs that you might need to change your brake pads:- You don't have the same responsiveness as when you bought your RCX and there's a lack of bite. - Your bike makes a strange noise when you brake sharply.- The thickness of the pad is below 0.5 mm.This article tells you how to change your brake pads:

Q: Changing your brake discs

Although disc brakes are designed to wear out the brake pads and not the disc, the disc will eventually wear out where there is heavy use.It can be dangerous to ride with a worn brake disc. It could break when braking sharply and hard.The maximum wear value of the thickness of the disc is around 10% of its original value. We strongly recommend that you change it when the wear exceeds that figure.160 mm front and rear disc.

Q: Greasing the bearings on your bike

To ensure your frame lasts longer, grease the bearings and abrasive parts of your RCX bike regularly. You should be keeping a close eye on the following:- Bottom bracket.- Steerer tube.- Wheel bearings.- Seatpost.

Q: CHANGING YOUR PEDALS

Are your pedals broken? NB: please note that the screw thread on the left pedal is inverted and that the pedal thus screws on in an anti-clockwise direction. The right pedal has a standard thread. Make sure to use the correct tool to remove your pedals as you will need to use some force to unscrew them.

UNBOXING

To help you get to grips with your new ride, here are some tips on using your RCX for the first time:

FIRST USE

HOW TO ADD A FRONT DERAILLEUR

TYRE PRESSURE

The first time you take your bike out, choose the tyre pressure carefully, taking into account the weather conditions and your weight.

For dry terrain, inflate your tyres to between 2.5 and 3 bars. For damp terrain, drop the pressure to 2 bars.
BEDDING IN THE BRAKE PADS

Running in the brake pads is vital when using a bike for the first time.

To run them in properly, we recommend you brake 20 to 30 times at over 25 km/h, without locking the wheel.Also make sure you don't stop between braking to avoid "freezing" and thus sticking the pads to your discs.
TORQUE SETTINGS

Make sure you tighten to the recommended torque, particularly the stem / handlebar (5 Nm) and seat post clamp (6 Nm).

To set your position properly on the bike, carry a set of Allen keys with you on your rides.

ADJUSTING YOUR POSITION ON THE RCX II

Steering position

To adjust your position, you can remove the "spacers" located under the stem. Once you've set everything up as you want, don't be afraid to cut the part of the blade that comes above the stem. We recommend getting a professional to do this in one of our bike workshops.

MAINTENANCE

Maintaining your bike is essential if you want to expand its lifecycle. That starts with regularly cleaning your bike, the frame and drive train.

Step 1

Apply a degreaser to your drive train. Place a cloth on top of the brake discs to prevent them from being covered with degreaser.
Step 2

Clean your drive train with the aid of a brush. Apply a suitable cleaning product to your frame.
Step 3

Drying your bike and lubricating your drive train.

GOT A PROBLEM?

In this section, we've listed the most common problems encountered with the RCX. To extend the life of your bike's components and avoid having to work on them, we recommend the following:

MAINTAINING/CLEANING YOUR BIKE

To extend the life cycle of every part on your bike and its drive train, you must clean them regularly.

Please refer to the section above to find out what to do.
WEAR

Your bike's wear parts all have a shelf life. If you don't replace them when necessary, it might cause other parts to wear more quickly or cause them to break:
- Chain: 5,000 km
- Cassette: 10,000 km
- Check the teeth on your chainrings and derailleur pulleys for wear.
TORQUE SETTINGS

To ensure you don't put too much strain on the various parts of your RCX bike, please comply with the torque settings that we recommend.

If the torque settings are too high, they can cause parts to break, increasing the risk of you falling.

CHANGING YOUR PEDALS

Are your pedals broken?

NB: please note that the screw thread on the left pedal is inverted and that the pedal thus screws on in an anti-clockwise direction. The right pedal has a standard thread.

Make sure to use the correct tool to remove your pedals as you will need to use some force to unscrew them.

YOUR DISC BRAKES ARE MAKING A NOISE

If your disc is making a noise:

- Check that your wheel is properly centred. To do this, loosen the wheel and tighten it up again.

- Check that the brake calliper is in the right position.

- Check the brake pads for wear.

- Check the tension of your brake cables.

Your derailleur isn't able to shift gears any more

If your derailleur is no longer responding to your gear changes, you may have to replace the cables and housings on the derailleur.

Watch our video tutorial to find out how:

Derailleur cables and housings

YOUR GEARS ARE SKIPPING

If the gears are skipping, you should check the following:
