Shimano Di2 electric bike shifterSee all photos
Many aspiring Lance Armstrongs will tell you that the future of bike technology is all about electronic gear-shifting. Unlike the traditional lever shifter, the electronic variety uses a motorized derailleur to move the chain from cog to cog. Thought by many to be faster, smarter and easier to use than a regular shifter, the electronic version only requires the click of a mouse-like button. The handlebar controls move both the front and the rear gears, giving the rider enhanced control over the ride with minimal effort. The shifter is powered by a removable lithium ion battery, which requires a 90-minute charge every 1,250 miles or so.
Even an amateur bike rider will be able to feel the difference between Shimano electronic gears and those on a standard road bike. The super sensitive shifter only requires a light press to move the chain in the front or rear derailleur and find the perfect gear. There's no sticking or bumpy shifting, making the action smooth and effortless -- getting the shift right every time. Of course, moving between gears may not be that big of a deal for those of us used to a Huffy, but when it comes to winning triathlons and road races, a smooth shifter is one of the key components to copping a gold medal to compliment your Lycra bodysuit. Expect to see Shimano's new line of electronic gears in various bikes in the coming months.
