We’ve seen a lot of angle-adjust headsets of the years, giving riders the ability to tweak their head angle slightly. But German upstart EMGR is taking a different approach.
Their new Virtual Pivot Headset allows you to change your fork’s effective offset by +/-4mm, for a total range of 8mm. The benefit is that you can now adjust your fork’s trail without affecting the head angle, which gives you a more precise way to fine tune your bike’s handling. The video above shows how it works…in German, but the visuals make it clear.
Rather than use angled upper and lower cups at opposing positions, the EMRG Virtual Pivot Headset either moved the steerer forward or backward in the head tube. This moves the axle in relation to the tire’s contact patch, and that difference in space is the “trail” figure in a bike’s geometry.
Fork offset is the distance the axle sits in front of the steering axis. It has an inverse relationship with trail – the longer the offset, the shorter the trail.
Move the steerer forward and you have less trail, which will make it turn more sharply but be slightly less stable at high speed. Good for tight courses where quick maneuvering is important. Move it backward and trail increases, making the bike more stable in a straight line and subtle, sweeping corners. But steering will feel a bit slower.
EMRG admits the changes in handling will be subtle, but for the rider who wants that extra bit of tuning, it’s […]
