TCS® 2.0 Flex Tape
Flex Tape is a thin, pliable tape that is applied over the indestructible Solid Strip to provide an airtight seal between our TCS (Tubeless Compatible System) tires and rims. Installation of Flex Tape is considerably easier than traditionally bulky tubeless tape. Flex Tape can only be installed in conjunction with a WTB Solid Strip on a TCS 2.0 rim.
What size tape do you need?
WTB recommends using tape that is 5mm wider than your inner rim width.
