The main reason I went to 1x was to clean up the crap on my handlebars and give me better access to my dropper remote. The shift lever was getting in my way when I needed to drop the post.
I’m not a good enough biker to feel the effects of the loss of 12 oz in weight I saved by removing the derailleur and shifter. Other than that, converting gave me the opportunity to gear the chainring (26t) and cassette (11t-42t) to where it fit my needs for climbing in New England.
