Shimano Ultegra 6770 Di2 Electronic Groupset Package

Shimano 6770 Di2 Electronic Groupset

Here at Sigma Sport we have pieced together the ultimate electronic package for your new build or to treat your current steed to a serious electronic upgrade.

You'll be hard pushed to distinguish between the performance of Ultegra 6770 Di2 and Shimano's top of the line Dura-Ace Di2 grouppo, with the major difference being in its slightly bulkier appearance, and of course- the price!

Electronic shifting provides incredibly fast, smooth and predictable shifting without the long throw or effort that is required for mechanical shifting. This is most noticeably felt in the Ultegra 6770 Di2's self-trimming Front Derailleur (FD-6770), which enables incredibly clean and easy front shifting; normally the stumbling point for mechanical groupsets.

The Electrical componentry of the Ultegra 6770 Di2 groupset is complimented by the same Chainset, Brakes, Bottom-Bracket and Chain found in the mechanical 6700/6750 groupsets. The Ultegra 6750 Chainset is built upon Shimano's Hollowtech II technology, renowned for its incredible strength to weight ratio and ability to efficiently maximise power through the cranks.

Shimano's 6700 Brake Calipers offer the rider improved feel and modulation, with a spring tension adjuster for a more precise set-up. Shimano claim that, thanks to new brake pad compounds, braking power is increased by 20% in dry conditions and 100% more in the wet, when compared to previous generations.
