Before your road bike gets back on the road after the winter break, you should give it a thorough check. TOUR workshop boss Hans-Peter Ettenberger shows and explains what is important. In this episode, you will find out what is particularly important for electronic and mechanical gears.
Mechanical gearsticks work with a Bowden cable and lever mechanism. For this reason, they can wear out and require corresponding care. In contrast, modern electronic controls with rechargeable batteries and servomotors are self-adjusting.
Battery status
While Shimano and Campagnolo use a central battery for the entire power supply, SRAM has a button cell (CR2032) on the left and right of the shifters for the wireless connection to the shifters. The compartment can be opened with a coin.
End stop
Precisely adjusted limit stops are important. They limit the pivoting range of the rear derailleur and front derailleur between the smallest and largest sprocket or the small and large chainring. This ensures that the chain does not rattle and cannot jump off. The setting of the end stops should be checked and, if necessary, adjusted at the latest when replacing components in the drivetrain.
Lubricate gearstick
With older mechanical Shimano derailleurs, it often happens after a long service life that the gear cable mechanism snags due to resinified grease. A little WD-40 at this point makes the driver mechanism supple again
Lubricate rear derailleur
If you haven't already put your road bike into hibernation well oiled, you should drip a few drops of oil onto the joints of the rear derailleur and front derailleur now at the latest. Shift through all gears several times so that the Lubricant gets everywhere.
