The ALVX AF frame by BSD features a super tech invest cast chainstay yoke which gives even more tyre clearance as well as stiffening up the rear triangle. Your wheel can be slammed at an extremely short 12.5" Chainstay length with no worries of your tyre rubbing! On a frame the highest concentration of stress is at the junctions between the headtube/toptube & headtube/downtube. To handle the pressures of modern riding, the required strength is achieved using a combination of butted tubing & external gussets. The dropout is cast as one piece, much stronger than a plate welded to a tube, 7mm thick to provide good support for your axle, & the small shape has been designed for grinding meaning there's no overhang to catch on ledges or rails, also the dropout is heat treated before welding making it extra tough. There are integrated chain tensioner bolts to keep the wheel in place. section Product Specs
