Rated 5 out of 5 by amazingly light yet again many thanks to crc for delivering this product within 2 days of ordering and a nice surprise of a £10 voucher thank you. i bought the road 27.2 version of this post and upon openinig the box was impressed with how it looked and how light it is. after reading the instructions which is recommended as it states turning the seat clamp 180% so that your'e tightening away from the slot in the seat tube but as my bike is carbon the tube is double slotted so i had no choice in tightening it in its original position but with only enough force to stop it slipping. the seat clamp was very easy to fit and within minutes the whole thing was set up and ready for a test run so as soon as ive had a few rides with it i'll add another review to give a true verdict of this product so heres to hoping it's as good as it looks. 29 May 2014
Rated 5 out of 5 by За эти деньги лучше вряд-ли найдёте. Использовал этот подседельный штырь один сезон-никаких проблем.Лёгкий,прочный,выглядит потрясающе.Настраивается немного дольше стандартных.При закручивании болта необходим динамометрический ключ-слишком всё миниатюрное. 03 March 2014

Rated 5 out of 5 by Light and easy to adjust This is a top quality seatpost. The new model has been redesigned so that there is now only one tightening bolt for the seat rails instead of two (which they had on the previous model), so it is now easy to adjust the seat position/angle. 16 April 2010
Rated 5 out of 5 by Brilliant company I've had the predecessor to this seatpost since 1993 - ultra-light, and never missed a beat. I lost a part & USE managed to replace it over 14 years later. Outstanding service & products, so now whenever I need a component, if USE make it I automatically strongly consider theirs. 14 January 2010
Rated 3 out of 5 by Presque parfait !!! Tige de selle très light. Dommage qu'elle nécessite une attention toute particulière si on souhaite éviter tout grippage. 07 August 2009
Rated 2 out of 5 by useless Bought this about a year ago and have had a number of small problems with it. Got a new saddle at the same time with slightly larger than normal rails. Wouldnt fit in the clamp so had to get USE's clamp for large rails- Still didnt fit. Many hours with a file later i got the saddle on but it's too tight to adjust the position or angle much without fear of breaking the already seriously bent bolt. Also the post is really more like 27.0 not the 27.2 written on it. THis means no matter how tight the clamp is (i've tried three different ones) it continues to slip down. and that's on a racer without ever going off road. Also jammed in a bit of a shim to try solve the problem and it just ate into the carbon. 19 February 2009
Rated 5 out of 5 by Excellent Post Used this post since early 2005 and still going strong - No problems whatsoever. Fitted to a short travel bike and used mainly in the Lakes i.e. it hasn't had an easy life. Basically just make sure you use a quality allen key when bolting it together! 24 December 2008
