Rated 3.1 out of 5 by 10 reviewers.
Rated 1 out of 5 by Difficile la regolazione e rumoroso Seppur la qualità di finitura della superficie mi pare ottima e resistente ai graffi, sconsiglio vivamente questo reggisella perché il sistema di regolazione dell’inclinazione secondo me è assolutamente inadatto e studiato male, oltretutto il mio è estremamente rumoroso scricchiola fastidiosamente nelle parti di bloccaggio della sella. Per eliminare o almeno ridurre il fastidioso scricchiolio ho provato a serrare la vite con una coppia di serraggio maggiore ma la vite con innesto torx mi impedisce di andare oltre certi valori di coppia per cui non ho risolto niente, continua a scricchiolare fastidiosamente. Ho pensato anche che il mio fosse difettoso, ma non ho mai chiesto la sostituzione a CRC perché esaminando attentamente il sistema di bloccaggio della sella penso che i problemi da me riscontrati siano dovuti ad un difetto di progettazione. 20 July 2014
Rated 4 out of 5 Sturdy and reliable for now! Great value, good looking post, only con is the clamp that needs decent amount on tightening 17 July 2014
Rated 4 out of 5 by is it just me as usual quality bit of kit , looks great,great price, well packaged & got it very quickly fitting the thing ok but check it carefully & make sure correct torx bit used with proper ratchet fitted mine &wasn,t clamped tight enough, seat came off sideways on test ride refitted & rechecked,rock solid now, make it tight but dont go mad well done again crc 30 May 2014
Rated 1 out of 5 by Defective Total dissapointment. The clamping mechanism is a real pain. Even after tighterned to the correct torque it would not hold the saddle securely. Thankfully I got a refund. 29 May 2014
Rated 5 out of 5 by This is Crank Brothers I use a brand that I like and love,Sturdy and stylish products. my bike adds a distinct style.I'm more than happy. 16 May 2014
Rated 4 out of 5 by Fantastic Value Took a gamble on this at £30 given some of the reviews but have had no problems once fitted. It's not your ordinary clamp design but tightened properly its rock solid. I'm using this on my road/commute bike so wont be getting too much hammer. Now at £23.99 its a steal! 01 May 2014
Rated 4 out of 5 Fiddly to set up but nice once done. I had to grease some parts in the head in order to get any tilt movement which due to the design is not very smooth. I had to buy a good quality torx tool to get the torx bolt done up tight enough to stop the saddle moving backwards in use having twisted the first torx tool I tried to use. On the good side though once set up it doesn't move, it looks like a quality piece of kit and it is lightweight. 28 March 2014
Rated 4 out of 5 by fair fast delivery, good price. well marked, the weight is fine and it is rigid enough. the clamp isn't creaky also.. 06 February 2014
