Fantastic addition to my gravel bike
Great dropper post for my hybrid gravel bike (Specialized Epic World Cup with drop bars). They were recommended (and installed) by my local bike store and I with the maximum travel of 180mm, in combination with the Wolf Tooth drop bar lever (not great). The dropper is responsive, and has no discernible wobble. I like that I can easily/quickly set it to any height based on the downhill.
Works great now, but time will tell…
Works great now and if it works well over a couple of years and a few thousand miles it will be well worth the price.
