anybody have any experience with the redline monocog 29er? i rode one around the parking lot at my lbs and it felt ok but i wish the chain ring was larger diameter. i was pedaling fast but not going anywhere. guy said he would swap the rear cog 19t for a smaller one but i still want to be quick on the flat. i thought the frame was aluminum but im looking around of the web and it says its 100% chromoly.
