The Ti Parts Workshop Titanium Seatpost for Brompton bikes should be the go-to upgrade for any Brompton owner. Titanium is without a doubt the best material for Brompton seatposts not just because of incredible weight saving but also because titanium absorbs much more road-shock than steel - making the ride on an already-smooth Brompton markedly more comfortable for long-haul commutes on ccracked pavement or weeklong tours on the saddle.

The seatpost is available in Standard or Extended lengths. The Standard is 550mm long which is 15mm longer than the standard Brompton steel post and ideal for people up to 5'11". The Extended is 600mm, 65mm longer than the standard post, and ideal for people 5'11" - 6'6" or just long-legged.

Made from aerospace grade Ti-3AL-2.5V Titanium, flared at the bottom, like the original Brompton seatpost to prevent it coming out and tapered at the top to allow you to use the brilliant Brompton Pentaclip.

The Standard version is 242g, saving you a whopping 143g over the stock Brompton Steel seatpost. Couple that with the increased riding comfort, this is a brilliant upgrade!
