Setup, Compatibility & Care
To begin your conversion, first remove the existing tube and tire, then clean the rim bed thoroughly to ensure the adhesive tape bonds correctly. Apply the 21mm tape in a continuous wrap, ensuring there are no bubbles. Insert the MK2 valve, tightening the locking nut firmly by hand—do not over-tighten with tools. Once the tire is mounted, inject the 120ml of biofibre sealant, inflate to seat the beads, and spin the wheel to distribute the fluid evenly. Periodically check the sealant levels through the valve and top up as needed to keep the puncture protection active.
