Absoluteblack oval road 110 4 chainring for sub-compact

Product Description The absoluteBLACK Oval Road 110/4 Sub-Compact chainring for Shimano 4-arm cranks with a 110 mm bolt circle diameter This oval 2-speed chainring by absoluteBLACK allows you to ride your Shimano road bike crank with Sub-Compact or Super-Compact gearing. This has the advantage of a very small gear ratio and thus proves to be enormously helpful on steep climbs. The chainring fits Shimano cranks with four asymmetrically arranged arms and 110 mm bolt circle diameter such as Dura-Ace R9100, Ultegra R8000, 105 R7000, but also Dura-Ace 9000 and other older models. It is made of premium quality aluminium and is characterised by long durability. Thanks to the oval shape, you optimise your pedalling movement, reduce the strain on your knees and move forward faster. Note: These chainrings are not compatible with power meters that have a circular spider (e.g. SRAM QUARQ, Power2Max). These chainrings are not compatible with SRAM Yaw front derailleurs. Combinations other than those mentioned above are not possible, including chainring combinations from different manufacturers. The small chainrings are supplied with bolts, which are absolutely necessary for assembly.
