I bought a Redline Monocog at the end of last last year to dabble in the 29er market - it is definitely heavy! I feel the build quality is excellent, but plan on upgrading to some avid bb7s if you want to be able to stop...the rim brakes are just not cutting it where I ride. Compared to my HT Giant Revel 1, I am slow on it, but I am still only scratching the surface. Im taking it for a few hour jaunt this weekend, so I should have some more data points soon enough.
