Brompton Seatpost - Extended - STEEL - Black
If the standard length seatpost is not giving you enough reach, then you may need an Extended Seatpost.
This seatpost can be extended higher than the standard post by a further 6cm (2.5 inches). This also means that when the bike is folded the saddle stands higher by the same amount (6cm or 2.5 inches). It may be worth considering the Telescopic seatpost if you need to store the folded bike in a height-restricted space.
Suitable for riders with a maximum inside leg measurement of 89cm (35 inches).
