However, I'd like to stick to reasonable parts that you'd want to ride and won't cause problems so no single chainrings, allen key skewers, thin tires, delicate wheels, ect. I'm even gonna try to avoid using Speedplay pedals
Besides the Beyond frame which is 2900g for XL, I know Paketa and Co-Motion claim to offer light frames but I couldn't find actual weights.
