In an effort to placate my lower back discomfort on a Caad10, I came across the hylix seatposts.
The lower back issue is absent on my Supersix, which has identical set up to the Caad10. I put 28mm tires, and it has helped some, but wonder if the hylix seatposts are worth the trouble. I’ve seen some on ebay, and they seem very lightweight, which is positive but not a priority.
If someone has them on the bike, please chime in.
