Tires/Tubes

Challenge's S.C. Seamless Latex Cross Tube is hand made for the highest quality. Latex tubes are usually lighter and roll with less resistance than standard butyl tubes. They also resist punctures. The S.C. fits tires 28 to 35mm wide, and has a 47.5mm-long valve with a removable core.

Limus means mud in Latin, which is exactly what Challenge's Limus 33 Tubular tire dominates. Its deep, aggressive and well-spaced knobs cut through muddy ground and grip great. You'll be zooming through the corners and off-camber sections thanks to its grippy side knobs, and powering up inclines with ease thanks to the tall center knobs. It's built on Challenge's light and supple 300tpi hand-made SuperPoly casing with polyester-reinforced sidewalls, and there's an anti-puncture strip under the tread. You also get a latex tube. Latex tubes are lighter, thinner and more flexible than butyl tubes, increasing your comfort, lowering rolling resistance, and helping to prevent flats, too.

Your search for an internediate, all-conditions 'cross tire is over! Challenge's Chicane can tackle it all, whether the course is dry and fast, or thick with mud. The grippy side knobs ensure you stay upright in every technical turn, and the center file tread rolls fast and smooth.

Whether it's fondos or races, Challenge's Strada Tubular tires are the choice of pros and enthusiasts alike. At 25mm wide, these tires smooth out rough pavement and chip seal. The core-spun cotton casing is light, supple, and offers an unparalleled ride. Pair that with a latex tube and you've got tires that carve the corners and feature incredibly low rolling resistance. The chevron tread provides excellent traction whether it's wet or dry. A puncture-protection belt under the tread protects your tires from road debris and helps you knock out the miles.
