[Carbon Ken]

Hi,

I'm currently in the market for a 27.2mm seatpost and although I was looking for a carbon fibre Easton EC70/90 or Raceface Next to help "smooth out" the ride on my hardtail, I just couldn't help but notice the Alien Cyclops.

Cambria bike is selling this 160g seatpost for $79.95 which seems to be too good to be true. (ie. They also sell a 195g Easton EC90 is going for $229 !)

Am I missing something ? Is the seat clamp inferior to the others ? Is it too fragile for mountain bikes ?

Anyone using one ? How do you like it ?

Ken.

are you deadset on a CF seatpost?
if not, i would make other suggestions.

not to bad mouth CF posts, but an Al post can be just as light, stronger, and cheaper.
the whole thing about CF posts "smoothing" out the ride is a crock. unless your running some crazy exposed length on your seatposts you wont benefit from it being CF, handlebars yes, seatpost, no way.
ive ridden both easton and LP CF posts and never noticed such a claim.

check out the Thomson Masterpiece post.. any post that's run on some of the lightest hardtails on the planet and fastest gravity bikes says a whole lot about Thomson.

I'd recommend a Moots Ti layback

The bent Ti acts a bit like a spring. It's not cheap, not really light, my 27.2, 380mm comes in at 232gms, and mounting a saddle is a bit of a pain, but it does take the sting out of the bumps.

I've got the Aluminium Cyclops and highly recommend it. I had no troubles setting up the clamp and it has held the saddle where I put it since then - probably a couple of months. The new clamp is definitely an improvement over the older two bolt one.

My take on carbon-fiber, don't bother on a MTB. Yes, CF does dull some road buzz but when do you actually get this on a MTB. The terrain on a MTB is on the most part too uneven for CF to make a difference. To top it off, CF posts definitely have the highest number of failures that I've witnessed in my days.

I would have gotten a Thomson Masterpiece as they are renowned as the best seatpost around but just didn't think my scrawny 145lbs needed that much strength, especially at the cost. Go with a Cyclops post in Aluminium, or if you really want to save those precious grams get the Titanium version.

I just ordered one of these in 27.2X420.

I looked on USE's website and found that the weight, 160 grams, is for the short roadie post. The 350mm post is 187 grams and the 420 is 212 grams.

Hi,

I ordered the 27.2x420mm as well. Let me guess... Cambria Bike ?

I'll probably chop off the 70mm to make it a 350.

You should check out USE's website. It has a comment in there about laser etching cutting through the anodizing and possibly causing problems with the alloy. For this reason I would buy a 350 instead of the longer on if you only need a 350.

I noticed that Cambria no longer lists the 420 length. I hope mines is going to be a 420 because I need the extra length, otherwise I would not have ordered a second seatpost at all. Yes, I ordered from Cambria.

 

[Carbon Ken]

I would have gone for the 350mm but they didn't have any in stock at the time I ordered. Their recent 20% special only applied to in-stock items so I went with the 420...

I should be getting it sometime by the end of the year. I'll post the weight when I get it.

My order for the 420mm one got cancelled by Cambria. I changed the order to a 350mm one so if you do get a 420 do you want to trade? I'll pay for shipping so it won't cost you any money, just the inconvenience of going to the Post Office or UPS or FedEx. Thanks!

The laser etching is a totally separate issue to cutting down. LE creates a potential stress riser in the exposed length of the seatpost. Cutting one down only has an effect on the bit of the seatpost you don't need (unless you overdo it!) - can't see why it should be a problem (on my Strike I cut the post to match the profile of the end of the seatmast - the bit I lost was doing nothing at all apart from dangling in the air).
