What kind of help do you need?

Yes. Branta C50 wheels have a 21 mm internal rim width and are designed to accommodate compatible tires from 25 mm to 45 mm.

Actual tire clearance is also limited by the bicycle’s frame, fork, brakes, and surrounding components. A tire’s measured width can differ from its labeled size after installation, depending on the tire and rim combination. Before fitting a different size, confirm the wheel requirements, tire-manufacturer compatibility, and maximum clearance specified for your bicycle model.

First, confirm that both the wheels and tires are tubeless-compatible. Review the wheel specifications for any tire-type, size, or pressure restrictions.

A typical installation includes the following steps:

• Apply correctly sized tubeless rim tape so the spoke holes are completely sealed.
• Install a compatible tubeless valve and tighten it securely without overtightening.
• Mount one side of the tubeless-ready tire.
• Add the tire manufacturer’s recommended amount of sealant.
• Mount the remaining tire bead and confirm that it is positioned correctly.
• Inflate the tire until both beads are fully seated.
• Rotate and shake the wheel to distribute the sealant, then check for leaks.
• Set the final pressure without exceeding the limits printed on the tire or specified for the rim.

Inspect the setup after the first ride and check sealant levels periodically. If you are unfamiliar with tubeless installation, have an authorized dealer or qualified bicycle technician complete the setup.

The maximum supported rider weight varies by bicycle, frame, and seatpost model. Refer to the “Weight Limit” information in the Technical Specifications for your specific bicycle.

Check whether the published limit refers to rider weight or total system weight. A system-weight limit may include the rider, bicycle, clothing, luggage, bottles, and other equipment. Do not assume that the limit for one X-LAB model applies to another.

The seatpost must also remain above its minimum-insertion line and within the frame’s permitted extension range. Contact an authorized X-LAB dealer if the applicable limit or seatpost compatibility is unclear.

Saddle angle is adjusted using the bolt or bolts in the seatpost-head clamping mechanism. The exact procedure depends on the seatpost design.

Loosen the clamp only enough to reposition the saddle, then adjust its angle and fore-aft position. Keep the saddle rails within their marked clamping range and ensure they are seated evenly in the clamp. Tighten the hardware gradually and evenly using the torque value specified in the owner’s manual or printed on the seatpost.

Do not exceed the recommended torque, as excessive force can damage the seatpost, clamp, or saddle rails. After adjustment, confirm that the saddle cannot rotate or slide before riding. (Add video)
