Mr richardson My daughter had outgrown her bike. This longer post, and the lay back saddle mount have made it usable again. It's very good quality too.
Mr Beattie Good quality and light
Mr McManus Reasonably light seatpost for the price, works fine and seems good quality so far.
Mr Zorotheos Great seat post for the price, easily adjust the angle, well finished quality product.
Peter Great value and good quality; required to raise the saddle height on my grandson's mtb - don't they grow quickly! - does the job perfectly at a very reasonable price.
Denes Basic seatpost, sturdy and suits a budget project.
Mr Goddard The seatpost is just what I wanted at a good price and with quick delivery.
Chris Good quality seatpost. Easy to adjust the seat angle once fitted. Great price from Merlin.
glyn Nice quality seatpost, came well packaged and arrived in good time.
Mr Friend Lovely budget seatpost. Plenty of metal for your money. Looks great on the winter bike. Recommended.
Mr FLOCKHART Well finished product providing a great range of adjustment for saddle and height to achieve a comfortable position on the bike.
