Wolf Tooth GeoShift 2d EC44 - EC49 Long
Description
EC44/28.6 Upper, EC49/40 Lower 2 Degree Geoshift Long 115-140 mm Head Tube Length
Adjust the geometry of your bike by changing the head tube angle by 2º with the GeoShift 2º Performance Angle Headset. It allows you to change the head tube angle by -2º to make for a slacker geometry for added stability on fast descents, or by +2º by using the opposite orientation of the headset to make for a steeper geometry for quicker steering with maximum front wheel traction.
The GeoShift Performance Angle Headset features a design in which the bearings sit at an angle that aligns with the steerer tube. This compares to angle headsets that have bearings that sit flat, which adds unneeded friction and stress on the bearings. This design with angled bearings also prevents the creaking that is common with angle headsets that feature a spherical design.

Stock Code:WTHSIS41U-8MM-KNOCK-BLK
Wolf Tooth Premium Headsets for Trek Knock Block are machined in the USA out of aircraft-grade 6061 aluminum with superior sealing for protection against the elements. Available in a variety of colors to match the style of your bike. These upper headsets are for Trek frames with molded-in internal bearing cups.
NOTE: These headsets are to be used only with Trek Knock Block system
rek developed Knock Block as an integrated frame protection system to prevent self-inflicted scuffs, dents, or cracks from spinning handlebars. Knock Block consists of a special stem and stop chip on the frame. The stop chip limits the turning range of the custom keyed headset cover. The top of the headset cover has notches that lock into corresponding notches on the headset spacers which also correspond with notches in the stem for the strongest connection to the steer tube. These parts work together to prevent the crown of the fork and the handlebar controls from hitting the frame.
Compatibility
- Designed to work only with Trek Knock Block system
- The top cap on these headsets have unique raised features that key to Knock Block-compatible stems (made by Bontrager)
- If spacers are needed, you will need to use special Knock Block-compatible spacers with notch features
Lower headsets on bikes with Knock Block DO NOT have any unique features, as they are usually IS headsets that are available separately.$118.00 (RRP) -

EC44/28.6 UPPER - EC44/40 LOWER Headtube Length: SHORT 90 -114mm
Adjust the geometry of your bike by changing the head tube angle by 1º with the GeoShift Performance Angle Headset. It allows you to change the head tube angle by -1º to make for a slacker geometry for added stability on fast descents, or by +1º by using the opposite orientation of the headset to make for a steeper geometry for quicker steering with maximum front wheel traction.
The GeoShift Performance Angle Headset features a design in which the bearings sit at an angle that aligns with the steerer tube.

The design with angled bearings also prevents the creaking that is common with angle headsets that feature a spherical design.
Wolf Tooth headsets are machined in the USA with lightweight, strong, durable 6061 aluminum. Our Performance Headset is built to include an Enduro black oxide coated chromium steel bearing, a one-year warranty, and three levels of superior custom sealing to protect bearings from the elements and prolong the life of the headset.
Note: the EC44 Upper/EC44 Lower is the new design of the ZS44 Upper/EC44 Lower and can be used in its stead. This new design was implemented because the constraints of a head tube with 44mm upper and lower require the upper bearing to be housed above the head tube (as opposed to inside the head tube as it was with the ZS44 upper design) for optimal performance.
Compatibility:
- Upper headsets ship with a star nut which can only be used on forks with steel or aluminum steerer tubes. For forks with carbon steerer tubes you will need a compression plug (sold separately; never use a star nut on a carbon steerer tube)$208.00 (RRP)Add To Cart
