I have not long build up a 29er, a Fisher Ferrous, with On One forks and just the one gear. This took a bit of getting used to mainly down to the rigid forks.
This weekend I was out on my Five Spot having only ridden the 29er for about 3 weeks and once I got over the fact I could not climb like I would on a roadbike I got on fine with the Spot.
Having said that I am re-aligning my expectations bike wise and am very keen to see what is coming out for the 2011 season in the way of XC / long ride 29er. The Anthem X currently looks like it could be a very good bet. There are also I am sure going to be some nice offerings from Trek / Fisher, Turner, SantaCruz etc.
