Rated 1 out of 5 by Truthstone Very disappointed...does not keep height under load
Product looks very professional and installs easily. However, it has a design flaw, the seat post does not stay clamped! Drops 2-5 cm under pressure. Taking a closer look it has very fine groves on the stem which a sprung loaded lever is mean to lock into. Just doesn't catch until the post has dropped a few cm's. Lots of mechanical wear as a result.
So, suggest you look elsewhere.

Rated 1 out of 5 by Tedi76 product should be recalled
Me together with 5 of my friends have bought 5 bikes equipped with this seat post.
In 7 months all suffered from extreme lateral play or simply they cannot stay up.
I think Crank Brothers should stick to what they do best pedals !

Rated 1 out of 5 by Scapegoat Works occaisionally - NOT FIT FOR PURPOSE
Flawed clamp is impossible to adjust on trail as once released needs a lump hammer to adjust. After 1 wet ride will not extend fully. Cover fell off on flat ride. Post has developed "slap" & now won't stay up.
I spend more time trying to get it working than riding
AVOID LIKE THE PLAGUE!!!

Rated 4 out of 5 by Njigsaw Kronolog post needs regular cleaning. Excellent customer service
Came fitted to new bike. After first few rides found it was losing pressure. Contacting importers i was prepared to replace seals and repair myself if I could source spares. They took post back, repaired and upgraded it wit no hassle. V impressed.
Post does appear to suffer from hydraulic lock if ridden and cycled regularly in v wet conditions. Water gets into outer sleeve.
Buy a pin spanner and dead easy to strip and clean to keep it tip top condition.
Spares a pain but importer can assist. Easy to maintain oneself.
Locking mechanism does tend to slip a mm or so from top position to its worn locked position.
Overall a decent product.

Rated 1 out of 5 by Anonymous After the first ride, it was discovered that the post always slide down 10-20mm and the post was worn. It was needed to return for maintenance!
I supposed the problem was fixed after the service! It gave you another problem as the post cannot return to top position due to leakage of pressure. The problem seems fixed after air injection! However the same situation happened again within 30 minutes after the post is pumped!
Just DO NOT buy it! It is absolutely NOT a qualified product in the market!
Or you will have your seatpost always travels in the sea and what you can enjoy is the free maintenance service!

Rated 1 out of 5 by Anonymous good for a week!
Hi. I was very happy with it on the first few test rides but then started failing on me (slipping down in mid ride) after 1 week of riding in the Alps and developed a HUGE amount of side play (can literally twist from side to side - good for steering from the belly whilst seated, but just feels wrong).
Note that the cable outer is not 100% static as claimed (like on a gravity dropper) as it needs to move up into the post a few millimetres as the cable inner pulls down (like a v-brake: cable and outer move towards each other). The protective plastic cap flew off during a bumpy descent so the innards were left exposed collecting dirt.
The saddle head clamp mechanism is just bad design as:
1) A bit of plastic must be fitted between the saddle rails so if you lose it whilst changing/fitting saddles you're stuffed;
2) the single bolt clamp is either not tight enough or locks-up and even after removing it it's impossible to adjust fore/aft or tilt the saddle until you stick the shaft in a vice (fortunately it's flat sided) and twist the saddle with all your might to unbind the clamp.
It also seems impossible to find spare parts!
A few positives:
- when you pull on the saddle for a hike-a-bike it doesn't stretch upwards like hydraulic seatposts;
- the handlebar switch is superb (1 star just for it)! simple, looks good, cleverly left and right reversible, unobtrusive and can take a few knocks/scratches.
Ideal post for me would be:
- Infinitely smooth adjustable travel (gravity dropper out);
- static cable routing (Reverb is out because hose hangs at the back when you lower the saddle);
- simple cable system (Reverb is out with its smooth but easily damaged/pulled out hydraulic hose)
- simple 2 bolt saddle head clamp like Thomson, Reverb, KS, Lev, etc (Kronolog is out!)
- simple side specific or reversible switch on handlebar: - KS Lev’s switch points the cable forward to avoid having different L/R switches but the cable pointing forward from the handlebar is difficult to route and looks awful - could be ‘fixed’ with the 90 metal degree tube used in V-brakes).The Reverb push hydraulic button is smooth but sheers off easily. The Kronolog switch is the best (too bad it seems impossible to find on its own though!) as it’s reversible, simple, sturdy and looks great. Gravity dropper switches are L/R specific, sturdy and look a bit retro, and they are easily available as spares on CRC.
So I've now fitted KS LEVs (come on CRC, get them in!) on 2 bikes, one using the switch from the defunct Kronolog and the other with a Gravity dropper switch. Both work ace. Only time will tell if the KS Lev will surpass the durability of a Gravity Dropper with the smooth operation of the Reverb.
I hope this helps

Rated 1 out of 5 by Anonymous My experience of the Kronolog came whilst demoing a 29er from my LBS. The bike was around 2 months old and had only been ridden at most once a week. There is no other way to put it but the Kronolog ruined the ride.
Basically after a few kilometers the post refused to go down with me just sat on the saddle (I am 13.5st plus riding kit) and needed some force for it to budge. A few km more and it refused to drop completely. This left me in trouble in a few sections of trail where you really need the seat out of the way. In an attempt to get the post to lower I then managed to tilt the saddle right back as the clamp slipped and I had to take the clamp apart to get it to move as it refused to move under anything less than brute force.
I suppose the lever is OK and I like the fact that the cable isn't routed to the seat clamp, but that's the only positives I can say about this post.
Take my advice (and the advice of the owner of the shop I demoed the bike from) and get a Reverb. Can get a Reverb for less money and they are by far a superior product. Had mine for over 12 months now and only had to bleed it once. Zero hassle.

Rated 4 out of 5 by Anonymous Habe 5 Monate auf die Sattelstütze warten müssen! Die Montage ist einfach. Nach 3 Testfahrten mein Urteil: Genial!!Funktioniert einwandfrei!
