They're invisible, and definitely not sexy, but without tubes your bike ain't going no where! This CST ACIMUT Tube has the perfect valve length at 48mm which is suitable for all alloy race rims, and most of the carbon fibre rims found on the market, as long as the rim depth is under 35mm. Just don't grab one to replace the one with a flat, always good practice to have a couple of spares in the gear bag. Nothing worse than rocking up for a ride and pulling the bike out of the car only to find a flat tyre.
