This model features a tough aluminium construction, which makes it perfect at withstanding all the challenges that come with all day epics in the mountains. Compatible with the preloader system (sold separately) that means that you can adjust your headset preload without loosening your stem. There's a reason why so many EWS Pro Riders use the One Up EDC Tool, in the event of mechanical, the EDC Tool is right at your fingertips with everything you need. One Up Components wanted to make the tool system available to even more riders, including those with previously incompatible forks & steel or carbon steerer tubes.
