Thanks. Before changing the wheels, you could lose weight as follows:
- dura-ace shifters: 200g
- dura-ace cranks: 100g
- dura-ace pedals: 50g
You’d already be at 8kg that way.
My wheels, ready to roll, weigh 3167g. Weight savings to be had:
- lighter wheels: 300g
- 28mm gp5000: 80g
- dura ace cassette: 100g
Who knows how much that would cost, but you’d be close to the weight weenie sl7s I’ve seen (at least those who list actual weight ready to ride, which is hard without pedals ;-))
