Online ABSOLUTE BLACK Chainring Road Winter oval 2X BCD 110/4 asymmetric | grey outer Ring

ABSOLUTE BLACK chainring Road Winter Oval 2-LK110 4 hole asymmetrically | gray exterior

The chainrings of Absolute Black are CNC machined from billet aluminum, creating the perfect combination of light weight and excellent durability for your bike. The oval shape smooths force peaks during the turn of the handle. Thereby you have, especially in the mountains, a smoother passage and the muscles tired less. The lower peak forces also reduce the burden on the knee.

The Winter chainrings are designed for training in poor Bet heritage endings. Compared to Absolute Black Premium chainrings are 30% heavier, but have much less cut-outs and are therefore less sensitive to dirt and easier to clean. With 5 millimeters strength they possess an enormous rigidity. Six switching ramps offer superior switching characteristics.Technical specifications:
