Those looking for the tubeless ride off road are in luck. While tubeless compatibility was once an exception to the rule off road, bike parts manufacturer Enve has stayed true to its goal. The company released the first mountain clinchers in 2006, and brought out the first full carbon fiber mountain clincher in 2008. Enve has now had several years to tweak the product as the clincher wheel has gained popularity. The latest is one to get up early for, the Enve AM.

Enve uses a proprietary manufacturing process to produce the Enve AM. It involves targeted laminate and a purpose-driven design. The rim is 30 mm deep and features a 24 mm width between the hook beds, which works for tires between 2.2-2.4-inches wide. Several structural modifications give the AM clinchers better ride performance and strength without adding weight.

The new tubeless compatible Enve AM rims are available in both 26- and 29-inch models and in hole counts of both 28 and 32 holes. A set will retail for $860 with pre-built wheelsets on DT Swiss or Chris King hubs start at $2400.

No Need to Pump It Up With Self-Inflating Tires

Nothing can ruin a bike ride like a flat tire. While a crash of course is far worse, a flat is just downright annoying and frustrating because it is fairly minor but yet just enough to get you off the bike. Now Benjamin Krempel has developed a system that could keep you riding instead.

The PumpTire system consists of a tire, an inner tube that clips into it and an air valve. The concept is a different as clincher tires are from tubular tires. Basically the PumpTire is designed to automatically pump air into the inner tube by actually using the compressive effect when the tire rolls. To ensure that it doesn’t just keep inflating, the tube stops pumping when the desired pressure is reached.
