I'm thinking about buying a 63cm Trek 2300 from ebay. I currently have a Giant OCR3 and have been riding for 2 years. I typically ride 2-3 times per week about 30 miles each. I am just a recreational rider. I am 6'4" 240 lbs and horrible flexibility. I have a 35 inch inseam. I have never ridden a Trek before so am I crazy? Right now it is at $760 ends in a couple of hours. It appears to be like new with low miles. Suggestions?
