LEESE LSE-PRO Carbon Fibre Crank Ultra Light Road GRAVEL Bike Bicycle Crank Arm For E-ASTON Direct Mount Chainring Crank XXE GP3

I have them as well which is why toxin's comment caught my attention. I have about the same mileage on them as you and I'm certainly happy with them for the price. There's not really a better option out there for 140mm cranks. I am however having chainline issues as well despite using LEESE's spider. I wonder if this could be due to the spindle length discrepancies others have mentioned here and on chinertown. Of course this could be due to a handful of other factors so I'm not giving up just yet, but I'll definitely be switching to 1x if I can't get the front shifting working smoothly.
