Argon 18 Nitrogen size Large with a 57cm effective top tube Used as my best bike for dry summer rides only. A very fast bike which is in great condition. I’m selling having bought an aero disc brake bike on the Cycle 2 Work scheme. Compatible with mechanical and Di2 groupsets I have a seatpost mount for the battery. The frameset will come with the following: - All aero headset spaces and top caps - Di2 seatpost battery mount - Assembly manual - C-Bear bottom bracket bearings The frame takes aero V brakes (which aren’t included) but I have a brand new set of Fourier brakes which are also available. Thanks for looking and if you have any questions please let me know.
