Built around our aftermarket Zebra frame and tapered chromoly Zebra forks, you"ll find a set of full chromoly bars, a sealed rear cassette, and a double-wall Alienation Black Sheep rim in the rear. The 400 Series comes in a 20.5" or 21" size, but only with a straight cable option to keep the weight down and give it a super clean look. Clearly, less is more with the 400 Series.
