I'll be getting another disposable MTB. Last year's is wrecked. I saw a really promising 9-speed SRAM Madwagon for about $100 at the sporting goods store the other day.
I need better lighting. Maybe a Trail Rat system.
I am going to get an insulated sleeve for my water bottle. I'll make one out of a telephoto lense cover or baby bottle sleeve.
All in all I was pretty pleased with last year.
