The ALVX AF+ is the latest version of Alex Donnachie’s signature ALVX frame. Featuring the same super tech geometry and ultra short rear end, but now with an updated invest cast chainstay yoke which maintains the tire clearance as well as creating a more rigid rear triangle and it also looks pretty sick.

✓ Invest cast chainstay yoke which creates more clearance for the tire for when your wheel is slammed, because this part is cast and heat treated it strengthens the rear end of the frame by stiffening it up
✓ 7mm thick invest cast dropouts to provide good support for your axle, and the small shape has been designed for grinding meaning there's no overhang to catch on ledges or rails,. The dropout is heat treated before welding making it extra tough with integrated chain tensioner bolts inside
✓ Brake mounts: none
✓ External gussets for strength
✓ Sanko Japanese seamless 4130 chromoly
