BONTRAGER RSL 31.6 SEATPOST

Having bought a carbon bike 10 years ago, it's been an ongoing project to get it lighter, in the last year I had gathered some parts together to get it down to 6.8Kg from 7.25Kg which I fitted recently, when I looked at the bike, the only remaining parts of the original bike were the frame, forks and seatpost, with this new addition I have a 6.65Kg road bike that flies under the radar at sportives because it's 'only a Boardman'. A 150g saving is significant and it also looks pretty cool too
