Makster - that stem (I'm pretty sure) is an an Odyssey Vapor. Would you mind posting a good pic of the stem viewed side on ?
I had one of these and the guy I sold it to was asking about cable routing. A pic would be really handy to pass on.
Nice looking bike. If you wanted to save some weight I'd start with the wheels, and I think you could make this change with altering the retro appearance much. Maybe some mavic 231cd rims with hope or xt hubs ?
Other fairly easy places to lose weight would be seatpost, bars, pedals.
Anyway, the main thing is that you enjoy the bike.
Here ya go...
Hope that helps matey.
Will probably be selling the Overburys this year as I hate seeing it just sat there. I've got other bikes that I ride and dont see the point in having something just to look at
