When I was shopping for my second bike, it came down to a GF Nirvana or Trek 7200. I went with the Trek 7200FX primarily because it had no suspension fork and thinner tyres. Which in 2005 the Trek was 700 x 35 and the Nirvana was 700 x 42, I believe. I see the 2007 models have 700 x 38. I now fine myself on roads 95% of the time and picked up a road bike with 700 x 23 tyres. And the thinner tyres are deffinitely faster on blacktop. Although 23 is too thin for me. I will be trying 700 x 28 on the 7200FX one of these days. Hoping to get some of that speed and hoping they still perform on a hard gravel trail.
