Hi there!

 

I'm making the switch to 1x11 on my surly cross-check. I'm going to buy a new crankset, and was looking at the new GRX 1x's. But isn't the 50mm chainline way too far out? If I'm using a 135mm QR rear hub, chainline in the back would be ~44mm (for middle cog #6). This means the chain would be centred between cogs #4 and #5, with cross-chain of 13.65mm on the smallest cog and 25.35mm on the biggest. Is the 25mm cross-chain too much?

 

Should I stick to road cranks?
