Okay. I have just (re)joined the club: Pulled the trigger and ordered a TimeLine (Gloss Black, 56cm). It should be here in about a week.
TT, I plan to take your advice and get an 18 tooth freewheel, and probably a 19 cog tooth for fixed riding (when the time comes). I'm used to having an 18 back there - my Trek was geared 38/18 and the Speedster was 46/18.
I'm looking forward to this.
