If you think your seatpost is carbon fibre, as is advertised as having, have a closer look! I recently purchased this bike and found out by accident that the seatpost is in fact alloy with a 'carbon wrap'. I complained to the retailer who at first tried to fob me off with small print like 'specification subject to change without prior notice' and then insisting Specialized has stated the alloy seatpost was the correct one for the bike, despite all advertising saying 'carbon fibre'. After threatening them with Trading Standards and the Trade Descriptions Act, the retailer gave me sufficient gift vouchers to purchase a carbon seatpost... and I get to retain the original seat post as well. If you've also been misled... COMPLAIN!!
