I just finished building up a new Pisgah and I'm amazed by the ride. I'm 6'5" and 225 pounds and Litespeed designed me a frame for off-road touring. The frame is very large but proportional.
I rode the bike yesterday on the flats and was impressed by the acceleration and power transfer. Today, I took to the hills and the superstiff chain and seat stays really help to make this a good climbing frame.
I approached 4 Canadian builders but everyone wanted to sell me a 29'er and I didn't want one b/c I plan on riding a lot in South America and you won't find tires and rims there.
Lightspeed then became my choice b/c I already owned an Ultimate and knew of their quality.
