Argon 18 Arsenic frame is specially dedicated to that increasingly popular discipline, Cyclocross. Features:

Fork and rear triangle designed to work together on the cross route

This frame and its matching As33 fork are designed to work as a unit. They are made in Argon18 exclusive CNC machined molds using complementary materials, with the same performance criteria in mind. With its aluminum steer tube and carbon fork legs, the As33 is a reliable, race ready fork. The rear triangle design offers plenty of clearance around the bottom bracket and brake to avoid mud build up.

Cross specific tube shapes

The top tube lower surface is flat for easier shouldering on running sections. Asymmetrical chainstays for more clearance and bottom bracket rigidity.

3050 HT Nano Tech carbon

Arsenic is a 100% carbon frameset. Argon18 tests has shown that 3050 HT carbon formulation offers sufficient rigidity and ruggedness for cycle cross use.

AFS Geometry cross version

The Argon Fit System is an optimized cycle geometry that facilitates rider positioning. AFS ensures: Easy positioning and ideal ergonomics for riders of all sizes. Optimal handling characteristics in all frame sizes. For the Arsenic, the AFS geometry has been modified to suit cross racing; Remarkable: Bottom bracket height is 1cm higher than on Argon18 road bikes for increased obstacle clearance. Wheelbase is longer for an extra measure of stability on rough terrain. Wheelbase measurement, per frame size: XS (99.2); S (100); M (101.4); and L (102,6).
