Save €44.99Tax included
The SHIMANO Ultegra FC-R8100 52-tooth outer chainring (official Shimano part number Y0NG98020) is a genuine replacement part engineered for 12-speed Shimano Ultegra Di2 road cranksets. Featuring HOLLOWGLIDE technology, its hollow-forged aluminum construction provides extreme torsional stiffness to maximize power transfer while keeping overall weight to an absolute minimum. Precision-engineered shifting ramps and tooth profiles ensure lightning-fast, highly accurate, and silent front derailleur shifts even under heavy racing loads. This chainring is specifically optimized to pair with the 36-tooth inner ring from the same series to form the mid-compact 52/36T gearing setup.
