Just wondering if your happy with the 450? I have $500 for a bike and wanted a 650 but its $200 more than the 450. Anyway are you happy or do you wish you would have gone with the 650? or atleast the 550 but the extra weight on the 550 isnt to appeling to me. Thanks for any info. Also If I go with the 650 I am thinking about calling them and asking them to trow in a extra set of normal pedals with the 650 think they might do that? I just sold my bike on ebay for $110 so I need something now.
