The Shimano 105 10-speed chainring for FC-5750 cranks
This Shimano 10-speed chainring is compatible with the 105 FC-5750 compact cranks. So it has a bolt circle diameter of 110 mm. Through functional features such as special tooth profiles, ramps and leading teeth (SG-X design), it contributes to the precise functioning of the HyperDrive system.
Mount: 110 mm bolt circle diameter, 5-arm
Teeth: 34 t, 50 t
Combinations: 34-50 t
- 105 FC-5750
- 34 t can also be used for 105 FC-5650 / Ultegra FC-6750 / Tiagra FC-4550

SG-X chainrings constitute a significant technological advance, as they allow extremely smooth shifting even under extreme load. Special tooth profiles, positioning pins and shifting aids allow the front shifting to go as smoothly and easily as you are accustomed from the rear components. SG-X chainrings ensure smoother, quieter and faster shifting.
Shimano´s front shifting system is based on the HyperDrive concept. The front derailleur, the HG chain and SG-X chainrings work in a coordinated combination to make shifting more reliable, faster and more accurate. Without HyperDrive, problems are quick to appear when shifting on the big chainring, especially when under load. Shimano's HyperDrive system solves those problems. The SG-X chainrings, Wide Link front derailleur and HG chain work together to improve chain control to provide precise and reliable front derailleur shifting that is especially beneficial in severe off-road riding conditions. The chainrings have an exceptionally high torsional stiffness. The tooth profile is specifically shaped to allow the chain to glide in both directions and be picked up smoothly while shifting.

Note to Type Designation:
The type designations (with one or two letters) indicate that the chainrings can be combined with each other. Since the large rings have specially shaped teeth and shifting aids that make it easier for the chain to climb, full shifting performance is only guaranteed with matching small rings - and vice versa. A chainring of type XY should therefore only be ridden with a chainring of type XY. The same applies to all other types.
