Finally got around to buying my Father's Day present (my wife told me to go buy myself a present last month, but I never got around to it). I picked up a new rear wheel (18" Warp 9) and paddle tire (Kings Turbo Paddle, 8 scoop). Haven't tried it yet, but it should help a lot. I'm hoping I won't have to adjust the chain with the 18" wheel. Also, I went with a 48 tooth sprocket on the sand wheel, which should give me a bit of extra room (compared to the 53 tooth I ride for dirt). Also, my son who broke his arm at the dunes last month gets his cast off day after tomorrow. The doc told him to wait for a week or so before riding, but after that its back to lots of dune riding! Whoo hooooo!
