    Smart Charger Output is not 41.8V

    NCM Moscow+ from 3x8 to 1x10 and it is awesome!

    I switched from the original 3x8 to 1x10 drivetrain and it is a fantastic change! Less weight, less controls and cables, easier to drive and enough ratios! You will need: - a single chainring (narrow wide to keep the chain in its place safely, I never had a problem. I suggest a 32T but you can...
