Pirelli Scorpion SmarTube 29 x 1.8/2.2 Presta 42mm MTB

The Scorpion™ SmarTUBE is a top - notch inner tube designed specifically for mountain bikes. It combines the amazing features of TPU (Thermoplastic Polyurethane), offering riders the perfect balance of puncture protection, light weight, and compact volume. Unlike regular butyl tubes, this one - of - a - kind inner tube has low weight and volume without sacrificing reliability. It's the ideal choice for marathon racers, trail riders, and enduro enthusiasts who need a lightweight, durable, and space - saving spare tube. Pirelli PRO athletes pick it daily as a spare tube because it's so light and compact. You can easily stash it in your back pocket or strap it to the frame. Whether you're racing or just training, always have a Scorpion™ SmarTUBE with you. Note: Do not use with rim brakes.

Using the Scorpion™ SmarTUBE is easy. First, make sure your bike tire is deflated. Then, remove the old inner tube from the tire. Carefully place the new Scorpion™ SmarTUBE inside the tire, aligning the valve with the hole in the rim. Inflate the tube slowly until it reaches the recommended pressure. When it comes to maintenance, keep the tube away from sharp objects to prevent punctures. Check the air pressure regularly, especially before long rides. Also, remember that this tube is not suitable for use with rim brakes, so avoid using it in such setups.
