+1 in agreement with all of the good things I have read about the trekking bars. Just finished my first commute with it equipped and wrapped on the FX. The position options were very nice and better placed than flat bar + bar ends IMO. I did want to stretch a bit more though (longer stem...).
Also, though it's hard to tell definitively, the "new" crankset seemed to make for a better ride. I think they're steel chainrings on alloy crankarms; the manufacturing quality of the rings is clearly to higher tolerances than the stock M191. The drivetrain seemed smoother and definately doesn't have the awful sounds the old crankset made. This may not be the best place to ask, but how high do you have to go in modern Shimano cranks to get a reasonably good set (out of curiosity only)?
There...I'll end my opinions on this thread with positive comments! (not that I will be riding it tomorrow

)
