Works Components -1.0 Degree ZS44-ZS56 angleset (102g).
Installed.
Really happy with the quality of the Works Components angleset I put on the Chisel so I ordered another one for the Yeti.
With the longer 160mm 27.5″ fork I plan to put on the bike it should slacken the head tube angle from 66.7° to 64.6° and correct the slackened seat tube angle (from installing a longer fork) at least a little bit (71.7° to 70.8°).
On install I noticed the head tube shape isn’t round, but a unique almost boxy shape (you can see the unpainted surface around the upper head cup). I freaked out for a second thinking I might be missing some sort of headset to frame interface but on inspecting other SB66 builds online and zooming into photos it turns out this is how it is.
