How much are you willing to spend? I ask this because your specs are pretty decent. I'm sure you could lose a few grams here and there but this is where it'll get expensive quick.kmoses said:
Just off the top of my head...
Foam Grips - a savings of between 50-80 grams
Stan's Notubes - about 120 grams for the set
Boones granny ring and alum crank bolts for a savings of ~40 grams
What pedals are you currently on? Eggbeaters are pretty light. Could save you between 100 and 200 grams depending on what you're using now and which eggbeaters you buy.
Possibly switching to a SRAM x.o gripshift shifters with an x.9 rear der.
Right here you're looking at close to 1.25lbs on the optimistic end.
...or just spend all that money on a nice wheelset. you'll feel the weight reduction way more.
Goodluck and keep us updated on your upgrade path.
