In this video, I transform a 2014 BMC Teammachine rim brake bike into a sub-6kg hill climbing weapon. I cover every step of the journey — from weight-saving upgrades to the final weigh-in. With a strict budget of under £1000, I break down costs, grams saved, and ride impressions. Want to see how I hit sub-6kg? Watch to the end for the surprise reveal!
