Strengths:    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


Weaknesses:    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.

Bottom Line:   
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

Strengths:    One of the few 34.9 posts out there.

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

Bottom Line:   
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.

Strengths:    Looks good? relatively light

Weaknesses:    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!!

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

Strengths:    looks good and reasonable weight...however...

Weaknesses:    ...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!


Bottom Line:   
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...

Converting Cobalt 2's to Tubeless

I have just obtained a set of Crank Bros Cobalt 2's, which as you may be aware require no rim-tape for tubes as the spokes are not exposed in the rim. I'm quite happy to run tubes but would like to give tubeless a go. So my questions relate to how I run a tubeless set-up. Looking at Stan's No- ... Read More »

Crank Bros Cobalt 2 29er vs stock Stan's Crest

I'm looking for a new wheelset for next season. I do some XC racing and I'm 165 w/o gear.I also do some trail riding as well, so I'm hoping for a wheel to do both. As far as advertised weight is concerned the Stan's are lighter, but I've heard some issues with the rim strength. I've heard pretty ... Read More »

Hope Pro 2/Mavic 717 vs Cobalt vs Fulcrum RM Zero

Been wondering is it worth changing my present wheelset (Hope Pro 2/Mavic 717 and DT rebo) to either a Cobalt or a Red Metal Zero. I read a lot of negative review on the Cobalt hubs, any revision done on the design? The 2010 Red Metal Zero looks decent but double the cost of the Hope wheelset.Read More »
