The name ZEN comes from Japanese "禅". The use of ZEN meditation will reduce stress and increase the power of concentration through emptying the mind of thoughts, which gives you significant performance gain. We named it ZEN in the hope that it will help you to obtain results you desire.

As SG75 Series use a proprietary taper called "SG75 taper", SG75 crank should only be used on SG75 bottom bracket.
