Seat Capsule Premio was designed to suit the needs of a wide range of cyclists thanks to its large carrying capacity. The high-strength thermoformed shell creates a void that measures 625cc and can hold up to a 29.2.35? or two 700x30mm inner tubes. The internal pocket dividers comfortably hold a set of tire levers, a multi-tool, a CO2 regulator and up to three CO2 cartridges. The location of the Boa Closure System and Guide Rail Guard have been optimized for stability and aerodynamics. Not only does this tilted position secure the capsule right up against your saddle when fully installed, but it also pulls it away from your seat post and legs. If you run a dropper post and/or have ever experienced rubbing from a saddle bag, Seat Capsule Premio is for you. Additional items seen in picture are sold separately.
