For a look at the geometry of each OS Bikes Blackbuck in all three sizes, including fork options, click on each pic. Thumbnails are arranged as follows: By height w/rigid fork and suspension travel in each size, left to right, beginning with Small. Note: axle to crown defines how ‘tall’ the rigid fork is as measured from the center of the front wheel to the bottom of the head tube. A smaller A/C number results in a lower front end and steeper head tube angle.
