I’ve received my 46/30 GRX crank that I plan to put on my gravel bike to replace the 46/34. I thought that I might just buy a 50 chainring and convert the 46/34 to a 50/34 for one of my road bikes. However after looking at the prices for just a 50 chainring I think I’ll just sell the 46/43. I didn’t realize how pricey they were. Heck, for not much more I can get a whole crankset.
