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
