I just picked up my first single speed and 29er on Saturday. I wasn't too crazy about the brown color of the 2007 Monocog, but once you're out on the trail it seems like a really nice color. I put on some eggbeater pedals and an old water bottle cage I had laying around and I was ready to go. It was 40 degrees on Sunday so the weather was cooperating for it's first ride. The first thing I noticed was that I was higher off the ground than on my 26er. Although the bike felt better than my 26 right away. I felt I was more stable in my cornering, which translated into faster corners. After a while I felt like was taking corners much faster than on my 26er, but it could have all been in my head since there is no computer on this bike. I really liked the way the big tires soaked up the bumps on the trail. It is a rigid bike and only a few times did I feel that a suspension fork would be a nice addition. The other big thing I noticed was that it seemed like I was able to stand up and lean over the front wheel more when pedaling hard. On my 26ers I always lose traction when I do that. So that was a nice surprise. Overall it was the most fun I've had on a bike in a long time. I couldn't be happier with the big wheels and the single speed. There will be many miles put on the MC29er.
On a side note. I will definetely be getting a geared hardtail 29er for racing. I am in love with the big wheels.
Here are some pics on the bike and trail. Sorry for the poor quality. I had to use my phone camera.
