How is a tubular tire fitted?
Attention: Tubular tires should be professionally fixed to rims using a proprietary contact cement (e.g. Schwalbe Tubular Glue)!
As a test, first fit the tire without contact cement (2, 8-10). Check the valve lengtah, using an extender if necessary. Recommendation: Fitting the tire on the rim beforehand using light pressure facilitates later permanent fixing.
Tire: Slightly inflate the tire until it has a round shape (2). Evenly coat the base tape with a layer of contact cement (3) and let it dry for at least 6 hours (5).
New rim: Remove grease and if necessary roughen the rim well with fine sandpaper (1). Follow the rim manufacturer’s instructions! Evenly apply a layer of contact cement to the Rim (4) and let it dry for at least 6 hours (5)!
Used rim: Examine the existing contact cement layer. An even and intact contact cement layer can be re-used. If the layer is very uneven, completely remove all remnants of the contact cement from the rim and apply new cement (4). Let it dry for at least 6 hours (5)!
Apply a fresh layer of contact cement to the tire and rim (6/7). Immediately put on the tire: insert the valve. Valve at top position. Pull the tire as firmly as possible, so that the final section of tire slips over the edge of the rim in an easy and controlled manner (8-9). Centre tire position. The edge of the base tape serves as orientation (10). Inflate to approx. 9 bar/130 psi (11) and push down on the whole of the tire’s circumference using your full bodyweight. Clean off any remnants of contact cement from the rim sidewall.
Important: Leave the assembly to rest under pressure for at least 24 hours (12)! Check tires regularly. Never ride on tires with a damaged or loose base tape.
