These MTB and road seat posts are aimed at both serious and the infrequent cyclists and mountain bikers too, and so will suit anyone who either takes part in competitive races or those who just commute to work – ideal for different types of terrain from smooth road to bumpy off road – assuming of course that you have a bike frame with a seat tube which measures 25.0mm at it’s widest (internally within the vertical seat tube). To calculate if this is the right fit for your mtb or road bike then just measure the widest width of your seat tube – this is the central metal tube that the seatpost is inserted into – alternatively simply measure the width or look for engravings on the old post that this one will be replacing).
