I wouldn't do it, because I don`t have any specific control problems, but if I was doing it, I would put the package/s on Craigs, and Kijiji, and say you have the bike/s without cranks, and brifters, and want to sell it for X or best offer. You can always reply to any specific offers as they come in, that you can't respond to their offers due to pending offers, which you hope is true. Ultimately this is a pretty weird sale, you just need the one person to get interested, but if you don`t have that person in your neighbourhood, it really doesn't mater what someone else thinks you should be able to sell this stuff for in some other area, or different market.
