I have a Pake C'Mute that I built up with mid-level parts and it weighs about 30 pounds. rear rack, full fenders, big headlight, barend shifters, compact cranks with mtn cassette, etc. I mostly use it for commuting to work- 7.5 miles on easy roads with just a few items in a rear pannier. I also take it out once or twice a week on long 30-50 mile road rides in Texas hill country or around town. for solo road rides, I remove the rear rack and sometimes the fenders to get the weight down a little bit to make the handling a little more nimble. my bike is clearly geared more toward touring but it feels like overkill. I am thinking about replacing it with a Novara Verita (and replacing the stock Verita wheels ASAP!) I am looking for something half-way between a touring bike for comfort but more nimble like a road bike. The Verita is really the only bike I am considering because, as an REI employee, it's a much, much better value for my money than a Surly Pacer.
Should I keep upgrading the Pake with some better tires and wheels or am I trying to make the Cmute do something it was never made to do?
