To better clarify my situation - i started back on the bike in Feb - quickly worked up to Trek 7.6 fx (with fenders/rack etc) and have been commuting (and doing weekend rides up to 40 mi) on that since April - I plan on keeping that - Keeping the bike safe here at work is not a problem -
it really is time for me to get a real road bike ... for the past few weeks I have been considering the trek 2.3 so I figured why not push it up a few bucks to the madone 4.5 for 2k - I'll be testing them properly tomorrow at the LBS - I fear that once I have a road bike I'll not want to ride the fx hybrid again - hence the question about the practicality of communting on a road bike.
I sense that I surely can and as many of you have said - 'commute on what you like'
So I don't know - ... there appears to be the issue of no eyelets to mount a rack on a road bike ... but I could just keep it lite with an under saddle bag...
thanks for your experience and your thoughts -
