A Big Step in the Right Direction
- I've used it several times
Gravel has been the fastest growing segment for the past few years and Shimano has finally done something about it. GRX is a much needed drivetrain but doesn't quite go far enough with gearing for us casual riders in the mountains. To start with, performance and looks are on par with Shimano's road groups, so really good. It's a very clean looking groupset. So if you've liked your Ultegra drivetrain but want easier gearing, going to GRX makes good sense. There's some compatibility between the two groups too which is nice. On these cranks the chainline is spaced outboard for tire clearance which hasn't really been an issue for most bikes and means they're proprietary which is frustrating. I went 1x and they do have mounting points for a small ring if I want to switch to 2x down the road. The chainring has no issues holding onto the chain on the rough rocky terrain I've tested it in. With no substantial complaints on the quality of this group my big gripe is the gearing options. For 1x (which I'm a fan of) Shimano only has 40t and 42t chainrings which are good options for a lot of riders on flatter terrain and for gravel racers but us bikepackers and for those big days in the mountains we need smaller rings - I've been using a 38t ring until now and would like a 36t some days. Sram's AXS drivetrain mullet builds are popular for that giant 10-50t range and mountain chainring, Luckily Wolf Tooth has a 38t option but If Shimano offered us more rings out of the box they'd have a perfect, more versatile group.
