For my new gravel build I installed Shimano's GRX 600 groupset with 2x Crank and I'm loving it. On my previous bike I had a Praxis 4832 crankset with Shimano 105 - not a fan. I've not had any chain drops and my chain doesn't get jammed in between front derailleur and crank as it did with the PraxisShimano set up. 4630 is great too - perfect gearing for gravel. 46 isn't too small for road riding and I appreciate the 30 on hills. I chose to go with RX 600 instead of RX 800 bc they don't make the latter in a 165. All in all I'm glad I waited for GRX to come out for my new build - it was worth getting a gravel specific groupset.
Shimano's GRX on my Niner RDO RLT gravel bike allows lots of dirt/gravel climbing.
46/30 rings are a winner. Coupled with a Sunrace 11-40 cassette allows riding most off road pitches. The 46 is big enough so no spinning out on descents. Surprisingly reasonable price. Highly recommended.
Good to see shimano finally launch a gravel line. My mechanic was able to rig my FD6800 front mech to work with this part in the meantime until I install the GRX when I do the yearly maintenance of the bike.
Installed this on my road bike two months ago and I couldn't be happier. I needed lower gears in order to keep my cadence up while hauling my big ass up the hills in this area. This 4630 crankset was the perfect solution. It works perfectly with the Ultegra 11 speed group and looks great too.
