Change Your Game
The award-winning AngleSet threadless headset makes it possible to change your game. You can transform the head angle of your mountain bike and dial in the perfect geometry to attack the trail with ease. The design of AngleSet is head-tube length independent and fits most popular head-tube standards for both tapered and straight forks.
Highlights:
Featuring 7075 T-6 aluminum cups and covers, and long lasting Zinc coated sealed cartridge bearings, the AngleSet is the only option for riders looking to change their headtube angle without sacrificing quality and performance.
The varying headtube angles are achieved through the offset headset cups and gimbal system. Each offset cup can create a steeper or slacker angle by rotating it 180 degrees. 0.5, 1.0, and 1.5 degree offset options.
ZN40 bearings are corrosion-resistant zinc-coated, machined steel cartridge bearings with hardened steel balls.
In 1992, we brought the Aheadset®, the original threadless headset, to market – kicking off a major change in the way bicycle frames and forks would be developed going forward.
The original design of that revolutionary headset is still found in almost all bikes on the market today.

The 2015 Tallboy uses a ZS44 Top and EC49/40 Lower headset. We used to offer an Angleset for EC49 but it could only be used with straight 1-1/8" forks and we no longer produce it...
You are correct...the EC49 headset uses a 52mm bearing. The upper ZS44 uses a 41mm bearing in case you want to replace both...
Did you mean the 2016 Anthem SX? If so Yes you can use the Angleset. Giant lists this bike as using a ZS44/ZS56 headset so you will need the Angleset part # BAA0504K. Make sure you have at least 20mm of fork steertube above/below your stem to allow for the increased stack height of the Angleset
Unfortunately No. The Megatower uses an integrated headset, which does not require press fit bearing cups, and the AnglSet requires press fit cups to achieve the offset.
We only offer the complete AngleSet kit, which comes with 0.5°, 1.0°, 1.5° cups.
Yes, we have factored in the extra stack of the EC cup and other AngleSet components, in the head angle offset.
