Is Ultegra Di2 lighter than mechanical?

For high performance bikes these days, half a pound is a lot. This being said, the Ultegra Di2 is only 80 grams heavier than the mechanical Ultegra group, so the weight penalty for going to electronic shifting is minor.

Which is lighter Ultegra Di2 or mechanical?

But here's a quick rundown anyway: Total weight for the full group, including non-electric bits like the cranks and brakes, is 2,482g. That's 80g more than mechanical Ultegra, 263g more than Dura-Ace Di2, 333g more than mechanical Dura-Ace, and 127g lighter than mechanical 105.

Is electronic shifting lighter than mechanical?

Traditionally electronic drivetrains add weight over mechanical systems. The lack of steel cables and complex shifting mechanisms inside the brake levers may save weight, but the electric motors and batteries involved often add that weight back in, and then some.

Is Di2 faster than mechanical?

Electronic shifting is faster than mechanical shifting. For example, Campagnolo claims that “shift times are now 25% faster that than the mechanical rear derailleur (taking just 0.352 seconds to swap sprockets)”. Campagnolo EPS offers the fastest shifting followed by Shimano DI2. Sram's eTap system shifts the slowest.

How much lighter is Ultegra?
