What would be the easiest things to do to lighten an old style Birdy? I recently purchased a used Birdy red and think a few upgrades may be in order.

Would a new crankset and bottom bracket make a significant difference? The newer ones seem to be integrated and I suspect of much lower weight. Other changes in priority order (or what would make the most difference first)?

Any thoughts would be appreciated.

Of course, your tires are the most cost-effective way to get the weight down. But it's most important to make sure you have the puncture protection you need. If you are in the US, Black Dog will build you replacement wheels with lighter hubs. The BB/Cranks isn't a bad way to start. Or you can put a rack on the back with wheels and then you don't need to worry!

This is from the Birdy thread. Some guy that got his to 8Kg:

change comfort stem for an "allround" one (ca. 100 g less, ca. 40g of
this due to the QR)
Stelvio tyres (ca. 215 g each, Maxxis are ca. 355 g each)
Cheng Chin inner tubes for them (ICE states they are 50g lighter than
Schwalbe SV-5A, which are 94 g each)
