Regardless of whether you're riding the road or the mountains, be prepared with the Topeak Hexus X Multi Tool tucked stealthily in your jersey pocket or hydration pack. This award-winning 21 function multi-tool features all the tools needed to make quick adjustments or lengthy trailside repairs. A full range of hex and Torx keys means you can tackle pretty much any loose bolt, and there's a chain tool for taking care of broken chains. Side-mounted tire levers integrated into the tool ensure you never have to worry about carrying a separate set of levers, and there's a Presta core tool for tightening or removing valve cores. Please note that the chain tool is compatible with single and multi-speed chains up to 12-speed, not including Campagnolo 11-speed hollow pin chains.
