Aluminum Shafting - Unfortunately, as you can see by our selection, Easton Aluminum does not make every arrow size in each arrow color. Consequently, the color design you prefer may not be available in the size you need. We apologize for this, but trust you understand that this is beyond our control. The sizes as listed begin with the weakest spine and progress to the stiffest spine. If you want your shafting cut to length, the extra cost is $6.00 per dozen. The length is measured from the bottom of the nock grove to the end of the shaft. You may order just one (or a full set if you wish) of any of the below full length XX75 aluminum shaft sizes for the purpose of testing and tuning as per our Black Widow Owner's Manual Companion DVD, to determine which shaft shoots best from your bow. Nock included, please specify size. We do not offer to cut tuning shafts to length.
