Comandante Red Clix is an upgrade for C40 Nitro Blade and C40 Iron heart grinders. With this axle, your grinder gets an expanded click range, which results in even greater precision. The Red Clix has twice as many grinding settings as the regular axle. At the same time, the grinding stays consistent and smooth. Especially espresso fans will find this super-precise adjustment second to none. If you are a demanding filter coffee geek, it will also hit the spot. The set includes an axle, a spring, two washers, a red dial, and a silicone wristband. Please be careful to only use the Red Clix axle together with the Red Clix dial mixing these with the standard axle and dial may result in damaging the axle.
