Will that come with electronic Di2 shifting? Will 10-speed Shimano GRX continue? We hope to answer these questions and more when Shimano feels the time is right. But considering 2x drivetrain popularity among pro gravel riders, we suspect there will be a 2x gearing option coming as well using the 11-36t cassette from the new Shimano 105 Di2 drivetrain. If it ain't broke, don't fix it I suppose.įurther, we don't know if this update to Shimano GRX will include 2x gearing. Will Shimano GRX continue to use the existing 11s lever shape and crank arms? Hard to say Lideen's bike sure does. Things we don't know?

The derailleur cage here looks to be 1x-specific judging by its shorter length.Īesthetically, the derailleur looks not dissimilar to the latest generation of Shimano Cues rear derailleurs, with more of a flat face to the derailleur parallelogram rather than the more intricate cutouts of the current generation derailleurs. This derailleur uses just a standard mount - again similar to their mountain bike derailleurs as well as Shimano CUES - that makes the derailleur look quite a bit more compact. Available today, boasting a huge 170mm travel, rugged carbon fibre frame and impeccably balanced geometry. Current-generation GRX uses the same direct-mount style as Shimano road derailleurs continue to use today which makes the derailleur quite a bit longer front to back.
