Rated 5 out of 5 by Отличный подсидел Дешевый, крепкий, красивый, на одном болте. Установка седла проще некуда. 22 July 2014
Rated 4 out of 5 by Great layback post This post is very easy and simple to install, took no longer than 5 minutes including removing the original and the seat from it. Follow the instructions and fit the seat before fitting the post to frame, I can see if you fitted the post first it would be a little more tricky. One point to remember is that although it says you can use an hex key, instructions suggest 4mm or 5mm neither fitted, a 3 was to small. Luckily I have a US socket set and the correct fit is. T-20, like a star hex key. 05 July 2014
Rated 4 out of 5 by Lightweight, stays where you put it.. Might not have paid full price. Looks good in black/red. Light 31.6 / 350mm = 283g. As all of the adjustment for the saddle position is with one bolt you feel as though you might need an extra hand whilst getting the right position (ie angle and position on saddle rails at the same time). Not really a significant problem though. Guides showing height and center useful. Std setback distance just right for XC bike. 21 June 2014
Rated 4 out of 5 by Quality product at a great discount price Bought a Cobalt 3 iron-black post at CRC's discount price. For the price it is a wonderful bit of kit. The dimples instead of laser or painted marks to calculate the height is a nice touch. The colour is a bluish hue, which may not be to everyone's taste, but throw in a cobalt 3 stem and they match almost perfectly (stem's colour is a bit darker, though). Anyway, the post seems solid, fitting the saddle does not take long (maybe I have been lucky, but I have had no issues with the clamp, as others have reported) and it looks nice, plus it's light (240 gr in my scales, 350 mm at 31.6 diameter). Will it break in mid ride? hope not, and it really doesn't look it will. 02 June 2014
Rated 5 out of 5 by хороший выбор Многие тут пишут о каких-то проблемах с затягиванием седла на данном штыре, у меня такой проблемы не возникло почему-то, приобретал для своего шоссейника, диаметр 27,2 длина 350мм - седло установилось и затянулось вообще без всяких проблем - легко и быстро, после этого на нем пройдено 150км и никаких абсолютно проблем с ним не возникло. Сам штырь очень легкий, внешне очень красивый, упакован в красивую коробочку, все в общем на высшем уровне. Не знаю может мне повезло, но лично мой экземпляр меня более чем устроил, доволен безумно! 18 May 2014
Rated 3 out of 5 by The clamp lets it down... I bought this seatpost as a lightweight replacement for a second hand road bike as it is lightweight, looks good and was on a very good offer at the time. The seatpost does its job as you would expect now that it's fitted properly, but it was a pain adjusting the saddle. The single bolt clamp is rated for a torque of 12Nm, and this NEEDS to be reached for the saddle to sit securely. However, undoing is then a pain as the metal in the clamp binds under the pressure and requires some force to free the saddle, making fine adjustment impossible. You can't adjust it properly by the roadside as without a torque wrench you will not be able to tighten the bolt sufficiently and the saddle will slide right back when you're riding. Once you have it sorted, it's fine- but I will definitely avoid these clamps in the future and stick to the easy two- bolt systems. 23 April 2014
Rated 4 out of 5 by Nice seatpost The iron color is not bright-metal as pictured, in real life it is more like dark grey. Weight for 30.9mm 400mm and 20mm setback is 270 grams 16 April 2014
Rated 5 out of 5 by Precioso acabado. Lo que era de esperar en Crank Brothers, gran calidad y a un buen precio. Esteticamente es mas bonita que en las fotos! 15 April 2014
