Good company

The only company that kept nukeproof parts available when CRC went bust. Ordered a bunch of times from them without any problems

Excellent service, excellent dropper post.

Post and all fitting kit arrived really quickly after I ordered it. The packaging was great quality to protect the shipment. Fitting instructions are clear and easy to follow. The post works really well. Very smooth operation in both directions. Lever action is high quality and the post returns to the fully up position as quickly as an dropper post costing twice as much. Excellent service, excellent post.

Easy to install. A bit tricky on a kids bike (Canyon Grand Canyon Youth 24)

Excellent service. Really easy to install, but because my sons bike goes quite wide at the seat tube the action does sometimes get a little stuck. Would be easier if there was a 125 external to it could be installed a little higher.

Post is good but the lever kit I bought with it was supplied with too short a cable

Post is good but the lever kit I bought with it was supplied with too short a cable.

Excellent post

Excellent post , easy to install and smooth action

Fantastic

I bought this as I had a brand x acsend before which last for 5+ years.

Same quality build on a budget.

I prefer the external option on my old frame.

Very easy to install.

Brilliant dropper. Low cost, and works well.

Brilliant dropper. So good I bought a second one for my partner's bike. I used to have a Rockshox Reverb, which was great until it died. However, this unit feels quite similar in action, but at a much lower price. Also I know I can keep this one serviced easily and cheaply. Highly recommended.

Absolutely brilliant bit of kit. Especially for the price, pretty unbelievable really!

Good product and great

Good product and great price!

No instructions provided

No instructions provided. I found a Youtube video of installation but it was so fast that until this day I don't know where the other knob goes. The other one did not fit until I modified it with file. The mechanism of the trigger is kinda crappy and the wire locking does not hold. It might have something to do with the other knob which I don't know where to put.

Outstanding Dropper post!

Outstanding Dropper post. Smooth and a very positive mechanism

Good Value and Works well

I had to query one or two points about installation..................both were quickly and knowledgeably answered by Ascend staff

Excellent price

Excellent price, quality and delivery. Used Ascend products on two of my bikes and here is the reason they are one of the best and quickly becoming the industry standard

Ascend Flight External Dropper 31.6/150mm + Evo Lever

This dropper is perfect, free next day shipping, super easy installation (took me 15 minutes), it looks great, performs flawlessly and all of that on top starting at only £100. As a package it has to be one of the best dropper posts on the market right now. 10/10
