Every year we see tons of next gen tech pop up on the road at pro races, casually hidden in plain sight at gravel events, or covered in mud in UCI cyclocross pits. These prototypes give us a good clue as to what to expect in the next year. But sometimes it’s simply whispers and educated guesses to predict the future of drop bar tech for road, gravel & cross…
12 Speed Shimano Dura-Ace Road Bike drivetrain?
It’s been a while since Shimano’s top road bike group has been in the spotlight. The current 11-speed R9100 Dura-Ace group first appeared in mid-2016. We got our first rides on it and weighed the mechanical and Di2 groups in early 2017. Prior to that, the R9000 series hit the streets in 2013. That puts it on a roughly 3.5 year development timeline, with the gap years being filled with Ultregra and then 105 trickledown updates. And both of those groups are full updated now, with virtually similar tech and shifting performance. So, if things stay on track, could 2020 could be the year of Dura-Ace R9200? And would it be 12-speed?
Here’s what we think: Yes, the next generation Dura-Ace will basically have to add a cog. Maybe two. SRAM and Campagnolo’s top groups are all running 12 speeds in the rear (for now…keep reading), and even Shimano’s own mountain bike groups have cranked it up to 12. So, it can’t be long until DA makes the jump, right?
Well, maybe. Truth is, the current groups work amazingly well. The reason they’re not bringing out a new XTR Di2 is that (in their words) they’re figuring out what would set it apart and make it worth the upgrade. Could be they’re taking an extra year for Dura-Ace to see where things are headed, like gauging the reaction to SRAM’s 12-speed gearing, then stretch the envelope. Or, perhaps their production is at full capacity getting the new mountain bike groups out…afterall, they do manufacture the high end groups inside their Japan headquarters.
Recent conversations with Shimano’s folks were focused on the off-road groups, too. As well as their shoes, and sister brands PRO Components and Lazer. We haven’t seen any prototypes at late season races, though, typically, those don’t show up until early Spring races like Tour Down Under. So, while development timelines almost guarantee they’re working on something, this one’s a tough call as to whether the next generation Dura-Ace will come in 2020 or 2021.

Micro Spline for the Road
When we do finally see a 12-speed (or 13-speed!) Dura-Ace group, it would stand to reason it’ll use the Micro Spline freehub standard. Currently, Micro Spline is MTB only, but it’s what allowed Shimano to squeeze a 10t cog onto the end of their 12 speed cassettes. Hopefully, if this happens it will be the exact same freehub for both road and mountain. Perhaps we’ll see Hyperglide+ shifting tech glide over to the road side as well.
13-speed Campagnolo road bike drivetrain?
While it doesn’t always feel like Campagnolo is the first to new technologies, they were in fact the first to debut both 10-speed (in 2000) & 11-speed (in 2008) road groupsets, the first 11-speed electronic group, then the first to deliver 12-speed road gruppos. (But not the first 10-speed electronic which was Di2 in 2009 or first 12-speed electronic which was AXS earlier this year.) Rotor then launched their 1×13 13-speed a full year and a half ago, with real availability this past spring.
We think Campagnolo likes being first on the road. And while they prioritize smooth cadence & gearing steps with their 2×12 setup, we fully expect them to go 13-speed to put themselves back on the forefront. They’ve already filed patents that push the smallest cog off the end of the freehub body, allowing them to drop to a 10-tooth (or even 9-tooth!) cog. More important than the tooth count, though, is the extra room this buys them on a standard freehub body and axle spacing…assuming the frame’s dropouts allow for such things.
While unsubstantiated so far, we’ve heard murmurs they’re working on a 13-speed group. If it pans out, we suspect we’ll see both mechanical and electronic EPS versions, letting them claim “first” on both a 2×13 and 13-speed electronic. And maybe that opens the door too…
