RED CLIX RX35 Product Overview

RX35 – Metric Precision Thread
Metrisches ISO Feingewinde DIN 13-2

RED CLIX, a unique combination of RX35 parts tailored for professional coffee experts in competition settings. Specifically designed with precision in mind, both the axle and grind grade dial feature an ultra-fine thread. The key advantage of RED CLIX lies in its expanded click range, accommodating the same particle size range and brewing methodology. With finer click steps, this specialized mechanism remains just as robust and stable as the standard version.

For instance, if your current brewing methodology involves 25 clicks, RED CLIX requires 50 clicks to achieve the same results. Similarly, adjusting by 5 clicks with the standard version corresponds to 10 clicks with RED CLIX, introducing an additional step between two standard clicks. This added level of precision can be advantageous for optimizing extraction time, particularly when dialing in lightly roasted specialty coffee espresso shots.

Important Note: Only use the special red-colored grind grade dial with this special RX35 axle. The extra fine precision thread on both axle and dial are very delicate and will get damaged if used with any other parts. Please make sure you do not mix Red Clix part with standard parts. Otherwise the RX35 parts will get damaged and can not be used any more
