A round-up of the best road bike groupsets from Shimano, SRAM and Campagnolo and rightly so with Shimano offering Dura Ace Di2, Sram offering Red eTap and Campagnolo offering Super Record EPS and where just getting started.
The groupset is the heart of any bike. Yes you may have an incredible frameset with the best road bike wheels, but without a chainset, gears and brakes you've just got an expensive garage ornament. The best road bike groupsets are super smooth and make a the bike move, and importantly stop too.
What's more, depending on the bike you're building, upgrading, or buying new, you have the option of electronic or cable shifting, disc or rim brakes, and depending on budget you can find anything in our collection from 10 to 13 speed options.
At the highest levels things are becoming increasingly electric and disc specific, as fewer and fewer of the best road bikes are coming with rim brakes as an option. Rim brakes haven't been phased out entirely, but brands are putting less R&D into upgrading their current offerings, and likewise high end rim brake wheels are becoming an endangered species. We know their not done yet though, stiffness has been increased as no one forget the weight savings that come with rim brakes.
Trickle down engineering, from groupsets of yesteryear now have tech from the very top end of the spectrum, making them an enticing option if you're speccing a race bike on a budget.
