I went to the Trek bike store in Fort Lauderdal yesterday and they only had the DS 8.2 21" in stock so I bought it and rode 20 miles. Felt like 5 miles because it rides so smooth and comfortable. I'm 6 feet 2 inches with a 33 inch inseam and the 21" fits great. I have the seat up high on mine. Can I get a saddle tube that acts like a shock absorber? This combined with a softer saddle would be real comfortable.
The front fork and rear frame has two mounting holes for disc brakes so I at least have that option but the pad brakes are really good. Mine is pearl white and blue. Really great bike to ride.
