E-Bike Gravel maintenance: how to regular handlebar and brakes on carbon Bora R

The appointment with the Gazzetta Motori workshop moves to the world of cycling, more precisely within the Very Motorsport laboratory, where the protagonist is one e-bike gravel with pedal assisted: the Bora R of Italian electric. It is a modern, multipurpose and light bike, designed for a mixed light-lighted-style use. The frame is in carbon fiber and the total weight, with integrated battery, stands around 14.8 kg, a competitive value for one Gravel Electric. Pedal assistance is guaranteed by an electrical system with 250 WH batteryperfectly integrated into the ora tube. The design is clean, with completely integrated wiring, hydraulic disc brakes and high -end components. A bike that, first of all, requires careful and specialized maintenance.

Fixing on the easel

–

One of the fundamental aspects to work safely on a carbon bike is the correct fixing to the workshop support. There Bora R It has a sensitive area: of the LEDs integrated in the back of the saddle rowing. In theory, the clamp should be tightened there, but to avoid damage, it is preferred to fix it to the horizontal tube, with extreme care and controlled pressure. Here a crucial technical principle comes into play: Carbon should never be crushed or blocked with excessive force, not to compromise its structure. A professional stand is therefore needed, like that of Beta Toolsrobust and with soft ganasces.

The driving position

–

On a gravel bike like Bora R, the location in the saddle is fundamental. Change the inclination of the torso by acting on the handlebar pipe (or attack) can make the difference in terms of comfort and efficiency. However, on modern bikes the operation is far from trivial. The reason lies in the fact that Modern pipes have aerodynamic formsthe brake and gearbox cables pass internally to the frame and handlebar and the thicknesses under the pipe are not simple cylindrical, but shaped and sometimes fixed. To avoid having to remove and reinsert the whole hydraulic system, Some thicknesses are “unacceptable”: They open laterally to allow the cable passage, avoiding complex disasters.

How to intervene on the height regulation

–

The adjustment begins with the removal of the rear cover of the pipe, using a 5 mm Bicgola key. Immediately afterwards, the two rear screws of the pipe with a 4 mm reneke, without removing them. The handlebar can thus be raised gently, paying a lot of attention not to force internal hydraulic cables. Once the disaccable thickness from the steering tube has been paraded, it can be repositioned above or under the pipe based on the new desired configuration. Then we restore the closing thickness, the fixed one, and the pipe reaches, aligning it with the front wheel. At this point it is possible Tighten the screws with the dynamometric key Set at 6 Nm, the value suitable for carbon components. Only at the end the cover is turned out, using a shorter screw if necessary.

Dynamometric key: the tool that saves the bike

–

Many underestimate the importance of the dynamometric key. But on modern bikes it is essential: the components are light and delicate and A too narrow screw can lead to the breakdown of the framewhile too slow can compromise stability. Unlike the motorcycle dynamometric, those for bikes start from very low values, even lower than the 4 Nm, ideal for M4 or M5 boltoning. To work on the Bora R, a key set at 6 Nm has been usedperfect for ensuring safety without damaging.

Disco brakes: return to the original for performance and safety

–

Second intervention of the day: Replacing the front brake disc aftermarket with an original one. The procedure provides for the removal of the front wheel, the disassembly of the non -original disc and the installation of the new disc with the screws supplied, equipped with braking. It is essential to respect the tightening pairs indicated on the disc itselfwhich are engraved or reported on the manual of the manufacturer. Once the new disc is mounted and the wheel reintegrated, it is good to check that there are no interference between the disc and the caliper.

Conclusion: a bike ready to pedal, safely

–

At the end of the interventions, Bora R is ready to face any path, with an optimized driving position and a perfectly efficient braking system. But the real message is another: Maintenance requires right tools on modern e-bikesspecific skills and very attention to detail. Even apparently simple operations such as the height of the handlebar or the replacement of a brake disc transform into technical procedures which, if performed lightly, can compromise the safety and performance of the bike. A’ordered workshop, adequate tools and maniacal care: This is the recipe to make a refined means like Bora R.
