Yeah wheels will be next most likely. I keep finding little issues I didn't spot because the bike seemed so clean and well taken care of when I got it. I didn't give it as thorough of a going over as I normally do. There has been side to side play in the crank for at least that final ride. The plastic preload part that threads into the non drive crank arm was the wrong one and too long. It allowed the crank to be set up wrong. And I found a ton of gritty grime on the seals of the original FC-6600 bottom bracket. Inside of the BB shell was spotless though! I degreased the crank completely before reinstalling with the new BB. I swapped in a used but mint looking Dura Ace 12-25 cassette and a new KMC XL chain. While I had the rear wheel and chain off I noticed how nasty the inside of the jockey pulley cage was. The rest of the RD was spotless, including the pulley wheels themselves. So I took apart the jockey cage and the pulleys and found a bit of a mess. Hard sticky gunk was covering the inside of the jockey cage, so bad that the dust cap for one pulley was stuck to it. I degreased all that, took apart the jockey wheels, degreased and cleaned them, lubed it all up, and put it back together. Oh and I also found the replaceable RD hanger very loose. Had not noticed that. I tightened it up but need to do some research to see if those little bolts need loctite or not. Anyway, a lot of little things wrong that most likely are what effected the performance. Hopefully today will be the last day of the much needed rain we've been getting so I can test it tomorrow. Gonna stay with the wheels that came with it right now but if it still feels sluggish I've got some others to swap in. Dropped another 3 ozs off this one. I really want this bike to fly because then I'm going to play around to get it as low into the 16 lb range as I can just for the heck of it. I've got some Look Keo blade pedals on the way as well as some nice Veloflex tires. They should be more plush than the Vittoria's to smooth out the ride a bit on the rough chipseal. Then I still have the bars, Dura Ace 7800 STI shifters, and some Dura Ace 7700 calipers for it. May even splurge for some 7800 brakes. for the heck of it. I'll probably redo the cabling and housing at the same time. Then this winter while all the good bikes are safely stored in the bike cave I want to get my first set of Farsports/BTLOS style carbon wheels. Just need to decide if I want to go tubular or clincher. The right wheels should take almost a pound off and where it'll truly matter.
