Ultra Light: - 1/4 the weight of standard butyl tubes - 1/3 the weight of ultralight butyl tubes - 1/3 the weight of tubeless sealant Ultra Small: - 1/4 the volume of standard butyl tubes. That makes them ideal as spares; also as a backup if you run your tires tubeless. Ultra Fast: - Less rolling resistance than butyl tubes or tubeless - Similar resistance as lightweight latex tubes, but without air leakage. Ultra Tough: - TPU is much stronger than butyl or latex. - We've increased the thickness slightly, adding just a few grams to gain even more pinch flat and puncture protection. - Rdden in Unbound XL (above) and during my recent FKT ride on the Oregon Cascade Volcanic Arc bikepacking route without any issues. Low Maintenance: - All-metal valves don't leak air like many TPU tubes with plastic valve stems that deform when the metal valve core is screwed in. - Easy to patch: Wipe with alcohol and stick on the self-adhesive patch. No sandpaper or vulcanizing fluid required. - TPU tube sealant seals small punctures.That's 4. Amazing ride feel that makes TPU tubes the perfect complement for supple high-performance tires. Our TPU tubes covers all tires sizes in the Rene Herse program, plus some. The program is simple and logical. Rene Herse TPU tubes come in: - 3 widths: Narrow: 20-32 mm (700C only) Medium: 30-48 mm Wide: 45-68 mm - 2 diameters: 700C / 29? 650B / 27.5? / 26? - 3 valves: 50 mm Presta polished 50 mm Presta black 70 mm Presta black That makes it easy to find the right tubes for your wheels. Our first shipment of the new SON Ladelux headlights with their high- and low-beam, charging port and sophisticated electronics sold out quickly. We just got another shipment that includes Ladelux headlights with pre-installed coaxial connectors. Simply plug the Ladelux into your generator hub, connect the switch, and you are ready to go. In the future, if you want to custom-tailor the wire length to your installation, just cut off the excess wire and solder on a new coaxial connector.
