There’s no denying the simplicity and popularity of dedicated single chainring drivetrains. But there are trade-offs with cadence and gear range. Easton is hoping to eliminate those downsides with its new gravel, adventure and cyclo-cross double chainrings.
Easton’s double chainrings come in three sizes, each intended for different drop bar genres. According to Easton, 47/32t is for gravel, 46/36t is for cyclo-cross, and 46/30t is built for adventure riding.
Easton two-ring specifications
- Claimed weight: 47/32t 194g, 46/36t 192g, 46/30t 182g
- Claimed weight on Easton EC90 SL crankset: 540g (172.5mm 47/32 without bottom bracket)
- Chainline: 45mm
- Material: EA90 aluminum
- Price: $149.99 (UK and Australian pricing TBC)
- Available now
The timing of Easton’s two-ring chainring release corresponds well with Shimano’s recently unveiled clutch-equipped Ultegra RX rear derailleur.
Unlike SRAM’s clutch-equipped rear changers, the UItegra RX rear derailleur is compatible with double chainrings up front.
