User manual BONTRAGER TUBULAR TIRE

[. . . ] BONTRAGER TUBULAR (SEW-UP) TIRE INSTALLATION AND CARE Before mounting a tire, make sure that the tire is the correct size for the wheel on which it is to be mounted. Use only rim cement that is specifically marked for gluing tubular tires. [. . . ] Use a solvent like white spirits or acetone. 1 tire has dried for approximately 10 minutes, apply a second layer of rim cement only to the rim. To install the tire 1. Holding the tubular at the valve, insert the valve into the valve hole of the rim (Figure 3). 3 5. Prior to use, let the glued tire and rim sit for a minimum of 24 hours. The rim cement requires this time to cure for proper adhesion. Inspection and care of tubular tires Before each use, inflate the tubular tire to the pressure recommended on the tire label. Also inspect the tire for any cuts or abrasions to the tubular casing, and for any cuts or fraying in the base tape. 2. With both hands, and working in opposite directions from the valve, apply tension to the tubular as you stretch the tubular into place on the rim. As you near the side of the rim opposite the valve, lift the tire up and into the rim well (Figure 4). If the tire slides across the rim cement, it will spread rim cement onto the sides of the tire. 4 WARNING! Do not ride a tubular tire that has damaged base tape. A tubular tire with damaged base tape may separate from the base tape, causing the tire to come off the rim. Replace a tire with damaged base tape before riding the bike. After use, inspect tubular tires for any damage. [. . . ] Apply a thin layer of rim cement to the rim well and the base tape of the tubular (Figure 2). Using the base tape as a guide, center the tire on the rim (Figure 5). [. . . ]
