Evil bike..?

You didn't say anything about the wheels.

What about the hubs? Are they the same as your other bikes? Maybe they're a different quality and just don't roll as fast? Maybe the bearings need a bit more maintenance?

Just pitchin' in.

All ideas gratefully received!! The hubs are Shimano 600, Ambrosio rim up front and Mavic rear. I completely disassembled them, replaced the bearings, lubed, reassembled, adjusted them when I rebuilt the bike. They spin nice and easily (only about 650km's on them), certainly as well as the hubs on my other bikes. Brand new XT cartridge BB, too.
To put this all into perspective, I normally do an avg speed or around 25-30km/h (15-18mph) on rolling roads/paths on my Gitane and Falcon on a nice Sunday ride. This bike I can just manage 20km/h (12mph) with the same effort. Just seems like I'm fighting to make it go.....

Maybe you're only riding this bike when you're feeling slow and full of lead? Maybe it's not the bike at all.

I 2nd a wheel swap for comparison.

I third the wheel swap idea. It looks like you have a mountain casette in the rear. I find when I ride the same bike with a 11-34 mountain casette vs 12-27 road casette it feels more sluggish cuz the gears are further apart, although if I am doing it cuz I really need the low gears, I need to do it. Your saddle also looks quite far forward in the pic, so perhaps you aren't in an effeceint pedaling postion. Do your other bikes have drop bars or flat? Could the twtichiness make me feel unstable and hold back on your speed psycologically. I don't understand why it was built with such a short wheelbase. Just some random thoughts. Please try the wheel swap and report back to us.
