Only one ride this weekend. Dadgum neck pain flared up Friday night and kept me in bed most of Saturday. Felt better Sunday, rode 50 mile with a new-to-me shorter quill stem -- 90mm to replace the original 120mm. Huge improvement. Better balanced, much more comfortable on my neck, feels more efficient because my weight is over the pedals on climbs rather than stretched out. I should have done this months ago.
I'd heard some claims that a significantly shorter stem can feel twitchy, especially on fast descents, but it felt fine to me.
