Sled Dog Racing
For Sled Dog racing the Cross Max 20HD is brilliant and continues to prove popular, and the Cross Max 29 is built for absolute speed. The Cross Max 20D+ has a suspension front fork and Hydraulic Disc brakes, for comfort and control, and the new Cross Max 29 has a Carbon Fibre Front fork, with hydraulic Disc Brakes, and larger wheels, all designed around being the quickest on the market. Just see some of the shots already.
If you want to talk to someone who has used both these Kickbike models for Sled Dog Racing, then talk to your local Sled dog club. They can offer you all sorts of advice and suggestions.
