The new Wolf Tooth Components GeoShift Performance Angle Headset gives you the ability to change your head angle by 1º, and it works on virtually any mountain bike, with any fork.
Made in Minnesota at Wolf Tooth’s factory, it’s sold in multiple sizes and versions to fit most any bike with a tapered head tube. It’s sold as upper/lower pairs, with ZS44/EC44, ZS44/EC49, and ZS44/ZS56 pairings:
So, it will work with the nearly invisible Zero Stack headsets that are more common these days, but not the fully hidden Inset headsets. The other option is based on head tube length, with options for 90-115mm or 115-140mm head tubes.
Technically, it gives you 2º of adjustment range, allowing for +1º and -1º, but we don’t see too many people opting to make their front endless slack. But you have that option. Just press the angle headset with -1º facing forward and slack will be added to the geometry.
That’ll give you more stable steering for fast descents, or switch around to +1º for steeper geometry and quicker steering.
How does the headset change my head angle?
Simple, really. Both upper and lower headset cups are machined such that the bearings are set into them at an angle. The angles are aligned so that the steerer runs through it straight…which is somewhat unique compared to some other adjustable angle headsets. This means less friction or potential binding from trying to turn a slanted steerer inside a headset with flat bearings. And, they say it won’t creak like bearings sitting inside a spherical cone.
Like their other Performance Headsets, the GeoShift Performance Angle Headset have:
- machined aircraft-grade 6061 aluminum cups
- Enduro black oxide bearings filled with high-pressure waterproof lubricant
- Dual-lip seals inside micro-grooves to protect bearings
The GeoShift Performance Angle Headsets are available now for $104.95, direct and at your local bike shop.
