Gels, a phone, a spare battery: the things you reach for without stopping. The Basso Apidura top tube bag keeps them at your fingertips in 0.4 litres, with a slim tapered profile that tucks behind the stem and stays clear of your knees, pedal stroke after pedal stroke. The proprietary Hexagrid nylon is waterproof, ultralight and abrasion-resistant, and at 72 g it barely registers on the bike. Semi-transparent panels let you find what you need at a glance, while the integrated cable port keeps a computer or phone charging as you ride. Bolt-on mounts give the cleanest fit; velcro straps make it universal. A small piece of kit that quietly earns its place.
