• Getting back to gearing: a friend has grx400 on his bike with 46/30 front paired with 11/36 which does seem easy enough and yet he wants to go even lower.
    Is an mtb double the chapest way to go? Also, das that warranty front der change?

  • 30 is already low on the front. What would a MTB double achieve? 28? 26 max?
    I would go bigger on the rear if the derailleur can handle it
