Picked up a bargain dropper from Amazon ( http://amzn.to/1tsnbXd ) and installed it today. Seems pretty solid and if lasts a year I’ll be happy. Tested it out around the neighborhood and it’s pretty cool; I’ve never ridden with one before. Action seems fine, drops then rises with lever press again. Not really any seat wiggle at all so that’s good.
The bike did jump to 28lbs with the dropper and the Thomson stem I put on. The carbon stem just didn’t feel secure to me.
