This is the latest version of Reed Stark's signature BSD Safari frame, updated with a shorter 12.8-13.2" rear end, which is a halflink shorter than the old version. It also utilises BSD's Superscoop chainstay tubing for extra tire clearance when your wheel is slammed. 

The Safari frame is designed to Reed's specification with a super long front end combined with a short back end and regular head angle. Simple yet effective!
