Retaining it’s best features this popular waterproof top tube bag now offers a ‘bolt on’ fitting option for greater flexibility when mounting on the bike.

The Altura Vortex Waterproof Bolt On Top Tube is an improved and updated version of our ever popular model. It now includes useful pre-punched holes that allow you to bolt the bag directly onto your bike’s top tube or it can be attached using the removable straps that are supplied.

Your belongings will be well protected thanks to the reinforced sides and base whilst the waterproof, welded seam construction will help to keep them dry if the weather takes a turn for the worse. The handy 1 litre capacity includes an internal pocket for smaller items whilst the cable port keeps things neat and tidy.
