Well this is a timely thread for me as I'm toying with the idea of replacing my commuter due to its weight.

I ride a Carerra Virtuoso, fitted with sks chromoplast mud guards and a rear rack. 23mm tyres. I carry a saddle bag with basic tools and a lock in it.
The bike is sold as a racer - it's not built heavy for strength or stability.

Total weight: 48.5lbs.
