The BBB Cycling BTI-71 inner tube suits road and gravel bikes running 700C wheels with tires between 20 and 28mm wide. Its Presta valve measures 60mm, giving enough stem length to clear deep-section rims while still reaching the pump head easily. Butyl rubber construction holds air reliably, making this tube a sound choice for routine replacement or as a spare carried on longer rides.
Matched to ETRTO 20/28-622/630, this tube corresponds to the common 28 x 0.75/1.125 inch sizing found on many road and gravel setups. Keeping a correctly sized spare on hand helps riders deal with punctures away from home without delay; a snug fit between tube and tire also reduces the chance of pinching during installation, supporting a cleaner, faster repair.
