Celerra DB

The new Celerra Gen. 2 is stiff, light and fine-tuned to reduce vibration and dramatically improves aerodynamic performance so you can ride faster with less effort. Engineered for performance with aggressive race geometry, the new Celerra is on the next level with a fully integrated, one-piece bar & stem combo.

Celerra DB 105 Di2 features the new SHIMANO 105, which brings Di2 shifting to a new set of riders. For those who have only experienced mechanical shifting and ergonomics, SHIMANO 105 Di2 represents a transformation of the road cycling experience.
With function and technologies inherited from DURA-ACE and ULTEGRA, SHIMANO 105 is the culmination of years of research and development. With a shared Di2 platform, sophisticated ergonomics, SHIMANO 105-optimized gear combinations, and an exceptional brake system, the new SHIMANO 105 marks a new era of affordable performance.
