Might be a far fetched goal but I weighed the bike and it tipped the scale at just over 31lbs.I would like to bring that down to about 25lbs. Not sure if this is possible. Most of the components are IMO heavy alloy and some are steel (bottom bracket, chainring, RD, etc. I would still like to keep the fenders and the rack.Now that I got some opinions, I would probably try to go with a 9-speed. Am I able to use current 11-speed RD's?
