Strength:

The only strength I found was the ability of the clamping bolt to break a number of torque wrenches, and drill bits.

Weakness:

The most useless piece of design i have ever had the misfortune to come across. If you manage to get the seatclamp bolt tight enough, then good luck getting it undone again. Ive brocken 3 Torque wrenches, at which point i braid an allen key sicket in, that didnt work, ground a slot in the bolt for a screw driver, that didnt work, now i am drilling the fecker out, thats snapped 2 high quality drill bits. My Brooks saddle is currently stuck in this useless piece of Sh** of a product. Never again will i buy anything crank brothers, may look pretty but the quality is the lowest standard ive ever come across.

Strength:

Lightish.

Weakness:

Slips every 2.5-4 miles.
Slips even more on bumpy surfaces.
Slips on climbs with lot of standing to sitting, sitting to standing.

After 1600 miles it is rather annoying. I did a century on this seat post and had stop get off loosen the Quick release extract the saddle out and tighten again. I tried not using any grease that just slowed the slip down. Not a help on a on a ride. Saddle is a faff to move.

I recommend you go to Super Star Components and get a cheaper, lighter, better looking carbon post.

Not a great buy. But if you've money to waste buy this. (Or take up Smoking.)

Strength:

At this point, none that I can think of!

Weakness:

The mill work of clamp that attaches to the post, is so poor that unless you loosen the bolts all the way, the saddle is nearly impossible to adjust. The clamp binds up on the post and prevents it from securely holding the saddle in place. The cheesy bridge that goes between the rails of the saddle needs to be a bit larger to securely grip the rails and not rattle around.
While trying to securely tighten this POS clamp down, my star but broke off in the bolt and is now holding my new saddle hostage!

I used to think highly of crank brothers products, but if they keep churning out crap like this, it won't be long before we see their stuff in Walmart!

Strength:

Picked it up for 20 bucks, so price-to-weight is tough to beat
Its a 5mm hex which is all over the bike, its nice to reduce the amount of different tools needed
Simple design, easy and infinitely adjustable. No indexing to strip out

Weakness:

Hasn't been a problem, but I wish the rail cradles were longer to provide a little more support for the rails of the saddle.

After reading the reviews I was expecting to throw this thing away immediately after never being able to get it on the bike. Turns out...
This is the simplest/easiest seatpost system I have ever used. Only trick (if you could call it that) is the not take the 5mm bolt out. There are spring clips to keep everything from coming apart while you slide to saddle in from the back. Grease post and insert in bike. Now tap the nose of the saddle to get the angle. Tighten bolt down. I'm not sure what all these other reviewers are having trouble with.

I have the no setback version. 30.6

other one and two bolt seatposts, they're pretty much all the same except the raceface, crankbrothers, and sunline posts

Strength:

One of the few 34.9 posts out there.

Weakness:

Does not hold the saddle. The design of the clamp makes no sense what so ever.

DO NOT BUY THIS. this is the worst seatpost I have ever used. The design is poor. You put this whack-ass bridge between your saddle rails and then put the rails in the clamp with the idea being that you smoosh all the stuff tigether si hard that the clamp-rail-bridge-rail-clamp sandwhich holds your saddle in place. Think about it like this....grab a piece of pipe, put it between your palms as if your were clapping and push your hands together as hard as you can to hold the pipe. Now have your friend push on the end of the pipe and see how easy it is for him to move the pipe. Does crank brothers make anything that is worth buying? How do theybstay in business? Oh yeah, thanks for using a torx bolt on the clamp, i was hoping to have to carry an additional wrench with me.

Strength:

Looks good? relatively light

Weakness:

Hardest post to adjust I have ever experienced. It will only really grab the saddle rails after an absurd amount of pressure is put on the bolt. In fact I thought it was defective when I was first trying it. When the bolt started to get tight there was still a ways to go for a good clamping. Hope the bolt doesn´t break. Stupid design for the clamp, stupid hex key. Tilt adjust is very hard (sticky!) unless you loosen the bolt alot and then the seat falls off!!

I´m considering returning this POS seatpost. Pay a little more and get a thomson!

Strength:

looks good and reasonable weight...however...

Weakness:

...it fails one of the fundamental requirements of a seatpost - the ability to clamp the seat securely!

Even if you do the security bolt (which is stupid in itself, unless you ride a MTB in NYC for some reason...what's wrong with a nice simple allen key bolt for frigs sake) up beyond the recommended tension, the inherently silly clamp design means that the seat creaks and slips...usually at fairly inconvenient moments!

Lucky to get one chili as it's not even a functional seatpost...and not sure what else you might use an expensive bit of aluminium tubing for...

lotsa others...never had an issue with a seatpost before this one!
