Rated 4 out of 5 by Looks good, does what its supposed to when its on but clamp is a sod The clamp is so fiddly to set your saddle just right. Lots of choise words were thrown about when fitting. other than that its super dooper! 28 August 2014
Rated 5 out of 5 by Great post, good bargain Light, strong and nice. yes, the clamp is bit fiddly but but better than 2 bolt in line system and you not changing seat every day anyway... I'm using it on my Cove Handjob XC and it make ride more enjoyable. Need to say I have 90kg and have the post just on limit (minimum insert mark) and never had any problem over year. Recommend to use carbon grip during installation. Now thinking about another one for my new commuter. 15 October 2012
Rated 3 out of 5 by Meh... My first USE carbon stem, dig the ride and the looks, but as others have stated, I too find the clamp system lacking. After a few months of both comp use and commuter duty, one side of the clamp is actually stuck and required copious amounts of lube and massaging to get loose. 2 hours total, not to mention freaking out thinking I'd have to replace it, just to adjust the angle and I didn't even tighten it that tight. Was faced evenly so not wedged, got it to the point of no movement when seated then an extra 1/5 turn to lock so user error isn't the issue. I'd absolutely love it if the clamp setup was better. It's a quality item. 30 March 2012
Rated 1 out of 5 by 225g HEAVY weight of the 27 mm version! VERY disappointing!! This might be a great seatpost - cool looks, seems solid (I did not try it out yet since I am considering returning it). However, IMHO the idea of buying a carbon seatpost is to save weight; that's why I picked the USE Sumo with a claimed weight of 185g, albeit for the 30mm/300mm version, where I needed the 27.2mm/400mm version. Unfortunately (and apparently for a reason), USE does not specify the weight of other lengths and diameters. However, I wasn't worried since I figured the mass of the weight would be in the head, and 100mm extra tube wouldn't make that much of a difference. When holdng the seatpost it is indeed obvious that the the carbon part is pretty light; the clamp however, seems massively heavy. That prompted me to stick it on the scales, where a VERY disappointing 225g showed up - more than 20% over the claimed weight! Shame on you, USE! And CRC, you should add a note to the specs saying that the actual weight is way over the claimed one... Bottom line - this may well be a great seatpost as USE generally builds, but don't buy this seatpost for lightness alone! 19 September 2010
Rated 4 out of 5 by Recomendable, relacion calidad-precio-rigidez imbatible, necesario engrasar casquillos, ruidos con el polvo y suciedad, de resto genial 18 April 2010
Rated 5 out of 5 by Quality product I have three of these posts, one on a cotic soul , one on a cannondale badboy ss and the 3rd on my evil soveriegn, all perform perfectly , no issues , no creaks , no slippage,all have the same quality finish , would buy another , don't forget to buy carbon paste fir fitting 08 April 2010
Rated 4 out of 5 by Overall, nice and lightweight, but i didn't like the clamp at all. First it's rather tricky to adjust it, then it doesn't fit saddles with oval rails (for example Selle Italia Flite). 31 October 2009
Rated 2 out of 5 by light, tube and carbon components well made and attractive, bond to aluminium perfect, seat clamp is rubbish. very fiddly to adjust slide and angle and when tightened to recommended torque can allow for seat angle to slip with an almighty crack on impact. one needs to tighten the crap out of the clamp bolt to stop the seat angle changing. 12 September 2008
