Well built but not for big guys

Well built but not for big guys. At max pressure It bobbed while i was pedaling, I am 6'5" 250lbs. So if your over that i do not recommend it. I gave it 4 stars because i am sure it would work well for lighter riders. Guessing 200 and under would work well but not sure above that.

I was searching for a dropper post for a while and saw this with air suspension. I bought it and installed it with the PNW loam lever on my Giant Talon 2 and its been amazing so far. It is not meant to make it feel like a full suspension bike but its meant to smooth out the rough bumps and big rocks that you come across. I highly recommend this for anyone who's in need of a dropper post.

100% diggin it
- Familiarity:
- I've put it through the wringer
threw it on a SC Stigmata with 650 wheels and it's just an all around good time bike now. where i notice the suspension the most is on rough climbs. the gentle suppression allows for you to maintain the pedaling power versus being bounced around from big rock to big rock. also super pleasant on the pelotas when you find a random pothole.
