While we’re mostly inveterate roadies here, when innovation strikes, we feel compelled to report on it – even if it takes us from the safety of the tarmac and onto the unbeaten path.
SRAM has announced the introduction of a new groupset, that not only up’s the ante in terms of adding another gear, but it also throws out the notion of having a front derailleur as well.
No secrets are betrayed when saying, that SRAM has been leading the way for 1X drivetrains to dominate the off-road/cyclocross segment.
However, the new Eagle groupset brings the total number of gears up to 12 now, sans a front derailleur, which SRAM says makes shifting both smoother and more accurate by virtue of fewer ancillary parts.
Furthermore, the company says, its succeeded in creating a better interface between the chain and chainring by way of taller, square teeth edges, that serve to better engage the chain earlier, as compared to traditional tooth profiles. And, perhaps most importantly in the eyes of the weight weenies crowd, SRAM says, “Eagle has a significant weight advantage over other drivetrains—XX1 Eagle weighs up to 300g less than 2x drivetrains with a similar gear range.”
While Eagle is clearly focused on the off-road market, we can’t help but wonder what implications it might have for road cycling?
Perhaps, by mingling either a 50 or 52-tooth chainring, along with SRAM’s wide ranging of 30 to 38 cassettes, it might yield a greater range of gearing, while also reducing the number of jumps between gears, in the mind of some road cyclists. Think gravel grinders.
However, that’s all based on supposition. Just exactly how a 12-speed cassette could interface with current 11-speed free-hub bodies, in order to produce accurate spacing and a proper chainline, remains unknown.
But, rest assured, once the math settles, some dedicated enthusiast will find out.
