Just noticed that Superstar components have an adjustable seatpost avaialable for 120 notes (Pure Racing Cobra i900L Height Adjust). 

Like the idea of an adjustable post but other posts I have looked at have seemed a) very expensive and b) subject to a range of reviews from "this is the best bit of kit ever" to "liable to break in anything other than beautiful sunshine".

Anyone used this particular seat post and got any views?
