Thanks Indy, very sound words. I don't want to go nuts upgrading a bike I have never even seen in person yet, but did read lots of pro and regular consumer reviews on this model where changing out the wheels for lighter seemed to be the chorus, so I will probably do it right away to get the discount. If there were no discount I would rather just take my sweet time with upgrading. The chain upgrade was so cheap with discount ($25) couldn't resist, since the guy said it really would make the shifting smoother. Smooth shifting, avoiding flats and being able to correct the one thing people complained on about this bike, sluggish start-up on hills, seem to be worthy investments for a thrifty person like me. Thanks again. I can finally turn my mind to other things having made these big decisions, which bike to get etc. 10 days 'til she arrives and then we ride !
