PRESS RELEASE: Wolf Tooth ComponentsThe New GeoShift Performance Angle Headset from Wolf Tooth allows riders to alter the geometry of their bike by changing the head tube angle by 1º. These are sold as an upper/lower pair, with ZS44/EC44, ZS44/EC49, and ZS44/ZS56 pairings and options for 90-115mm or 115-140mm head tubes. This new headset was designed, engineered, and machined in Wolf Tooth’s Minnesota machine shop.
Two positions are marked on the GeoShift Performance Angle Headset: +1º and -1º. Position the angle headset with -1º facing forward and slack will be added to the geometry, which creates more stable steering for fast descents. Conversely, switching the orientation of the headset will add 1º to the head tube angle and make for a steeper geometry and more responsive steering. Both angle options are indicated on the headset along with dashes that need to be aligned with the centerline of the bike. Full installation instructions can be found on the product webpage.

This new angle headset has a design that sets the bearings at an angle that matches the angle of the steerer tube. This design reduces the friction found in angle headsets that have the bearings that sit flat. The angled bearing positioning also limits the creaking found in angle headsets that have a spherical design.
The GeoShift Performance Angle Headset is part of Wolf Tooth’s Performance Headset product line that was first launched in 2018. These are lightweight, strong, durable headsets made with aircraft-grade 6061 aluminum and have a triple-sealed system to protect the bearings from the elements. Performance Headsets use black oxide bearings made by Enduro. These bearings are engineered to use the largest possible ball size and are filled with high-pressure waterproof lubricant. A pair of dual-lip seals ride in micro-grooves to further protect the bearings from water and debris.

MENTIONS: @WolfToothComponents
Take a look at Turner bikes to see what happens when companies don't stay in front of trends.
I guess this wolftooth would come handy to slacken the old switchblade a bit though.
Replacing the 27.5 wheels with 29'ers has lifted the BB from 326 to 338mm (estimate) and it's brilliant. The extra hight has made the ride more dynamic, seemingly without loosing any perceivable stability.
Perhaps the higher BB allows it to "tip" into corners with less effort? Not sure, but I do know that I can now pedal on terrain that isn't billiard table smooth.
I'm gonna change the game and start running 1° of lateral angle to the right on my steerer
Not to mention the price, almost double, not seeing the worth in the WT offer.
I have had a few, regardless of if only one cup is offset, the bearings are still angled - how would they align otherwise?
They all do it the same way, as its the only way of doing it.
VP made a side-of-the-trail adjustable one almost a decade ago (@mikelevy previewed it at the 2011 Taipei Cycle Show) but it’s long discontinued.
So many almost-good bikes can be rectified.
Got a -2° slackeriser in a Vitus Mythique to give a contemporary 65° HA.
Plus it steepens the slightly-too-slack SA
Ran the Works, btw. Can't say enough good things about that headset!
I've moved to somewhere that's steep and rocky. There are times now when I wish it was another degree slacker, but from others' experiences it seems like that throws off the balance of the bike a bit. I'll keep it at 66 and get a new bike in a year or two that will be likely in the 64.5- 65 range.
there's a nice animation here www.offsetbushings.com
Adding little stack to the bottom compensate the loss of stack from slackening the head angle, keeping the bikes total stack almost the same. It's the correct way to do it. Works did it the opposite.
WT keeps the top bearing in the center, which does not shorten the reach, works moves it backwards and unnecessarily shortens the reach.
WT is probably fully sealed, comparing the the Works which is known not to be sealed well and eat more bearings than average.
Works $90 shipped to US/CA
Wolf Tooth $114 shipped to US/CA
I would say extra $24 are totally worth it for all the above benefits.
- The WT top bearing is not in the centre, it is offset, clearly seen in the images, it is just by a smaller amount and even then it will be something like 1mm vs 2mm for the Works 1.0 setup - that’s right, you save a whopping 1mm reach at the bearing.
- The WT lower cup doesn’t have a larger stack, it’s internal just like the Works one (in 44/56 option) so there is no compensation for stack.
Several yrs ago I did 1.5 degs plus an extra 10mm travel on my v1 bronson and the change from 67 stock to @ 65 is glaringly and v enjoyably obvious. I have used Works headsets on several bikes and all without any probs years later
Does anyone make a good tool to install anglesets? Perhaps something that could key into the bearing recess to drive them in straight?
Or how do other people do these?
I have always made a cardboard wedge and used the park tool press...but there has to be a better way...
It would be cool if manufacturers of angle headsets sold matching drifts for installation, but they would probably cost as much as the headset. Actually, if you had two sets of the same angle cups you could use one as a drift if you flipped it and spun it around to cancel out the angle...
Come on Marshy, make them for us!
I have basically done exactly what you described, I use the cardboard wedges to stop from marking them at the final stages. But as a professional mechanic, I feel like a garage BMX brat using a wood block or mallet...it just isn't right...also, I have found they often spin a few arbitrary degrees (even when they are started 1/4 inch or so straight) and they need knocked out until luck finds them clocked straight in the frame - super annoying, and cant be good on frames.
Thanks for your comment.
Picked up another -2deg Superstar one for £35 in their recent sale.
Twice the slackening for half the price.
Edit: actually seems like they've been around since 2011.
2001 called... They want their stem back
