Easton makes them with the
EC90SL Tapered.
Though their website is a bit messed up and has the description on another fork...Look
Here for that one:
New for 2010, the supersized EC90 SL Taper fits the latest crop of frames with tapered head tubes. Like all forks in the EC90 family, the new SL Taper incorporates Easton’s unique ITT™ Internal Thread Technology, which eliminates slippage and possible steer tube damage caused by traditional expanding steer tube plugs. Any rider will feel confident knowing that the EC90 SL Taper features one-piece continuous CNT™ carbon monocoque construction.
For 1 1/2” lower crown races and 1 1/8” upper races, 55cm crown diameter, 43mm rake. ITT™ anchor nut easy to install and makes steerer tube less prone to damage. EDO™ carbon dropouts.
