Electronic shifting is the cream de la cream of precise, consistent, and lightning-fast gear changes. Electronic shifting stays as intuitive and efficient as mechanical, but with advantages like less maintenance and better performance in the elements because of fewer moving parts and adjustments on your drivetrain. Leading manufacturers like SRAM and Shimano offer various groupsets, prices, and performance levels for your road and mountain bike. Sure, it’s not the cheapest upgrade you’ll make but because it’s easy to use, includes customizable shifting and programming, and is ridiculously efficient, you’ll be beyond stoked you made the decision to go electronic. 



SRAM AXS rolls you smoothly into the 21st century with predictable and smooth wireless shifting that seamlessly integrates with electronic components and software. And no, you don’t need a degree in IT because SRAM makes it ridiculously easy to set up and use from the get-go. With a simple app on your phone, you can control and personalize your shifting, check battery life, or monitor your bike’s performance. SRAMs AXS road models include Rival, Force, and RED eTap AXS. Mountain bikers will gush over their AXS GX, XO1, and XX1 series, featuring airtight derailleurs with superb clutch technology that keeps your chain quiet and on the bike. 


Shimano Di2


Shimano Di2 offers instantaneous, precise, and customizable shifting. From changing buttons on your shifters to setting up automatic and customizable synchronized shifting, Di2 makes it easy to dial in your ride. With one of the lightest electronic groupsets on the market and the longest-lasting battery, road riders will love the easy upgrade to go the distance using Ultegra and Dura-Ace Di2. For mountain biking, Di2 is offered in XT and XTR groupsets and GRX for gravel. Don’t let the price tag steer you away lightning-fast, effortless, and precise shifting adds up to less energy being used and a greater focus on your ride.
