Time for an update, I guess.
Did a lot to the bike lately, which resulted in a 2.65 lbs weight loss.
The goal was not light weight as such, but better performance in general.
The discs for instance are heavier than the original ones, but they handle the heat from city racing a lot better.

Considering that the tyres are more than a pound heavier than the originals and that mine also carries lights, bottles and a speedo, I'm quite pleased with the result.
Any further weight savings would necessitate the use of carbon (which I'm no fan of) or would require such light parts that I'd be afraid to ride it hard. I'd rather lose some weight myself.
It can still cruise all day and is very comfortable, and it'll still race just as happily as before.
However it's certainly gotten better at the racing bit without sacrificing any of its cruising capabilities.
The only thing that bothers me a bit is the rear mech. Way too much silver on there.
I might get the 2012 XT version, as that is nearly all black. Then it's a matter of finding a better crankset and a black BB to finish the bike off.
