Do Tour de France riders use electronic shifting
The team uses Dura Ace Di2 shifters, derailleurs, and brakes mixed in with parts from its official sponsors (some bikes also have aftermarket derailleur pulleys).
Do pros use Di2
The shifters you'll see far more than any others in the Tour de France are Dura-Ace Di2 simply because Shimano sponsors and supports more teams than any other brand. This is Romain Bardet's bike with the handlebar turned so far forward that the drops point slightly upward.
Are electronic gear shifters worth the money
“Exactly,' McCarthy says. “It's great if you have injuries, injured hands, anything that can make it hard to ride a bike, electronic shifting can help. It works the same if you have cold hands or big gloves too. If you don't need dexterity because it's so easy.”
How much does it cost to switch to Di2
An Ultegra Di2 front derailleur will set you back about $560, while Dura-Ace Di2 is about $780. Ultegra Di2 shifters are $445; Dura-Ace Di2 are nearly double that at $930.
How good is electronic shifting
“It's great if you have injuries, injured hands, anything that can make it hard to ride a bike, electronic shifting can help. It works the same if you have cold hands or big gloves too. If you don't need dexterity because it's so easy.”
Can electronic shifting get wet
When it comes to washing your bike don't worry about the Di2 components. Your bike won't electrocute you when riding in torrential rains and it also won't explode if you get it wet washing your bike. As long as all Di2 ports have either Di2 wires or dummy plugs in them, they're pretty much waterproof.
Is electronic shifting lighter
The gap is closing, and depending on the bike and gearing setup you wish to use, electronic can be lighter in some situations. In the case of Shimano, the weight penalty for electronic gearing is now under 100 grams. SRAM's wireless system is actually heavier than the company's equivalent mechanical group.
Is electronic shifting better 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.
Do Tour de France riders use Di2
It's a bike that has now been ridden to five stage victories in the 2021 Tour de France. Like the SL7s used by Deceuninck–Quick-Step, Bora's are equipped with Shimano Dura-Ace Di2 groupsets and Roval Rapide CLX wheels.
Do pros use electronic shifting
Over the past decade, electronic shifting has quickly grown in popularity. Most high-end road, gravel, and mountain bikes come equipped with an electronic groupset. Almost all professionals use them. These days all of the major manufacturers including Shimano, Sram, Campagnolo, and FSA all offer electronic groupsets.
