California bike company Niner will release the Niner Air 9 Carbon Hardtail Mountain Bike in 2010, which is obvious since it is a 2010 model. Labeled by Niner Bikes as the ultimate, lightweight race frame, you can use the Niner Air 9 Carbon 2010 Hardtail Mountain Bike as a singlespeed or geared. Some features you might notice since they are one past models like built in carbon brake guides and moulded carbon dropouts. The tapered headtube adds strength to the front, which also improves steering. The frame alone will cost you $1,899 while return customers can reserve a frame with a $500 deposit. As a complete, the sizes are small, medium, large and extra large, plus two colors will release, vana white and tang.
