Assuming the fork was cut to the Tri155 stem , you have ~29mm of clamping area to work with. 2018? and newer frames are shipped to the dealer uncut.


Compiling from the IA10,14,16 megathread, the following should work (thanks, Synnove):
--Felt IA Dagger (110mm) (16deg)
--TriRig Alpha X/Sigma X (100mm) (17deg)
--Syntace Flatforce (44mm-111mm) (15deg)
--FSA SI K-Stem & Non-Series (NS) Stem (60mm-120mm) (20deg)
--BLK-Tec M3 (80-110mm)

Ones that might fit:
--Thomson X2 Elite (80-130mm) (10,17deg)
--PD Aeria Ultimate Stem (70,100mm) (12deg)
--Culprit Aero (don't think ever came to existence)
--3T Integra LTD (least certain on this one)
