Wolf Tooth 2 Degree GeoShift Performance Angle Headset Head Tube Length:Long 115-140 mm The F3 prioritizes acceleration andAdjust the geometry of your bike by changing the head tube angle by 2 with the GeoShift 2 Performance Angle Headset. It allows you to change the head tube angle by 2 to make for a slacker geometry for added stability on fast descents, or by +2 by using the opposite orientation of the headset to make for a steeper geometry for quicker steering with maximum front wheel traction.
