What's the difference between these Chris King headsets?
Jenson has two versions of a tapered headset on their site.
Chris King I3 44/49 ZS Tapered Headset > Components > Headsets and Spacers > Headsets | Jenson USA Online Bike Shop
and this one:
Chris King Nothreadset Ec Taper Headset > Components > Headsets and Spacers > Headsets | Jenson USA Online Bike Shop
Other than the cosmetic differences, the upper one has a much lower stack height. Is this compatible with any frame and fork or is it designed for a specific setup?
I'm mounting this to a 2012 Yeti ASR-5 alloy and want to make sure the upper one fits before I buy it.
