Welcome to the after-sales service page for your Triban RC520. We have made this bike versatile and comfortable by giving it an aluminium frame and carbon fork. The cable-operated hydraulic brakes are powerful, while the tubeless ready wheels reduce the risk of a puncture. The Shimano 105 groupset provides quick, smooth gear changes.
To help you assemble your bike, take a look at our video tutorial! Pay special attention when assembling the stem: the screws which hold the handlebar to the stem need to be tightened in a cross pattern with a torque of 6Nm. Check it out now.

To set your saddle correctly, it's important to fasten your seat post properly. A loose seat clamp runs the risk of your saddle dropping during your ride. On the other hand, if you tighten it too much, you might crush your seat post and therefore damage your bike. The best way of tightening your seat post is to use a torque wrench. We recommend tightening to 6 to 7 Nm. Be careful not to exceed the maximum height shown on the seat post.
To know whether your pads are worn, you'll need to check the thickness of the brake pad lining. If it's less than 0.5 mm, you should change them to prevent your brakes becoming less effective.
You're sure to find the answer to your questions in the FAQs
Are your pedals broken? Do you want to swap your pedals for clipless ones? Follow our tips. Please note that the screw thread on the left pedal is the other way around. You therefore screw this pedal on anticlockwise. The right pedal has a normal thread. Make sure to use the correct tool to remove your pedals as you will need to use some force to unscrew them.
If your disc is noisy: - Check that your wheel is properly centred. To do so, undo the screw then re-tighten it. - Check that your calliper is set properly. - Check that your brake pads aren't worn. - Check the tension of your brake cables.
If you notice that your brakes aren't very effective, there are several things you can do: - Clean your disc using a brake degreaser. - Check that your brake pads aren't worn. - Check that the cable tension is OK.
If your gears are skipping, you should check: - Whether your drivetrain is worn. - The tension of the cables. - That the derailleur hanger isn't bent. After that, adjust the derailleur.
Are your chainrings worn? Do you want to change the number of teeth? It's easy to change your chainrings. To do so, simply use an Allen key to undo the screw that holds the chainrings on. Then install the new chainrings. On this bike, the minimum chainring size is 34t.
