ergotec High Crab 2 Ahead stem

As a stable, yet relatively lightweight connection element between fork steerer and bicycle handlebar, the solid High Crab 2 by Ergotec has a fixed place among straightforward stems with rigid angle. The 35° angle of the 3D forged aluminium body can – in relation to the frame geometry and the selected radius version – help create an upright to moderate sitting position. The 4-screw handlebar clamping allows for easy mounting without dismounting the handlebar attachment parts. Shape, colour design and surface finish of the High Crab 2 make a discreet contribution to the look of your bike.
