Jack in the News

“We are very impressed with the design and function of the dropper post.”

“It all adds up to one awesome product and definitely one you should consider for your next dropper.”

"For those who ride hard, and those who hardly want to worry about maintenance, the Manitou Jack is a solid choice."

Orgasmicly smooth

Right out of the box you will find it smells a bit like the bikeyoke revive 2.0…
The lever that comes with I have not had a chance to use yet, but I like the short throw on it and am eager to try it out.
Further, after getting it out of the box and onto the bike, it just needs a few revive cycles, and after that it is good to go! Rode 85 miles on it the first weekend and it was faultless, and buttery smooth. Also noteworthy that the bikeyoke guys have a 3.0, and the Jack post (2.0) could be given those updates as well with a few parts from bikeyoke - but I truly see no need.

At the current sale price there is no reason not to buy a couple of these.

Simply Amazing

Have only heard great things about this dropper and can say I was not disappointed. It was super easy to install and is so much smoother than the Fox Transfer I'm coming from. Definitely would recommend!

Can't Be Beat

All of the features of my favorite dropper (bike yoke revive) with my favorite suspension company's logo on it! Buttery smooth, and I'm sure it will be as long-lived as the others I have in my fleet!

The perfect post

Everything I love about my BikeYoke post in a Manitou package! Knowing I won't have to rebuild my post on riding trips is refreshing. It always works flawlessly. If you're on the fence commit to it and you will never look back. 12/10 would recommend.

Jack 80 mm review

I purchased two posts to use on Specialized Epics ridden mostly on Midwest singletrack. Install and setup was straightforward on both bikes, and did not require any additional effort other than minor adjusts at the release lever. The seat post is a well made and light weight compared to a rigid post.

The lever is a solid unit for a manufacturer provided piece. It has a nice shape with plenty of position adjustment.

After a few rides, I found this to a great component that works well. I does this job reliably with no additional thought. For the type of riding we have in this region, this is an excellent choice.
