Specialized Thorn-Resistant Presta Valve Tube Tube

We all love to stop and smell the roses, but like they say, every rose has its thorn. And as we all know, there's no better way to ruin a beautiful ride than with a thorn in the tube. No need to worry, though, because we designed our Thorn-Resistant Presta Valve Tubes to combat pesky pricks of all shapes and sizes. Starting at the basis of the construction, we designed the tube to be thicker at the outer side (the part against the tire) in order to stop pesky bits from puncturing all the way through the tube. Then, at the inner side (the part against the rim), it's actually thinner in order to reduce weight. This way, you don't have to sacrifice performance in the name of protection.

  • A heart of gold, presented in our lightweight yet durable Premium A1 Aluminum, the Rockhopper’s butted aluminum frame features hydroformed top and downtubes in order to keep weight low and strength high, all while providing increased standover clearance, slick internal cable routing and dropper-post compatibility.
  • Beautifully beastly, SRAM Level hydraulic disc brakes pack a mean bite but deliver their power with a refined, intuitive feel to make for a package that punches way above its pay grade.
  • Bringing our Rx Tune to Rockhopper for the very first time, the lockout-equipped SR Suntour XCM with custom Multi-Circuit damping brings size-specific travel and spring rates to the show in a performance that’s sure to impress while also ensuring consistent geometry, handling and suspension performance, regardless of frame or wheel size.
  • Keep things simple with a durable 1x MicroSHIFT drivetrain that offers plenty of range along with a clutch-equipped rear derailleur that keeps your ride quite—and your chain on.
  • Pair dead-reliable hubs from Formula with our 25-millimeter internal diameter, hookless Stout rims for a wheelset hat-trick: strong, light and durable.
  • With the goal of making sure that the Rockhopper offers both the best fit and best performance for every person, no matter their measure, we’ve paired each Rockhopper frame size with the optimal wheel size. The result is a Rockhopper to fit every rider and the assurance that every Rockhopper is rolling on the best-handling wheel for its frame size.
