The latest version of Alex Donnachie’s signature BSD frame, the ALVX AF+. Steep head tube, short back end and equipped to handle the largest of tyres. This frame is clearly a tech street machine designed to respond quick. However, the 8.7 standover balances things out to keep the short and steep features looking and feeling like a bicycle and not a scooter.  “So, for the updated ALVX frame, the ALVX AF, we kept all sizes the same. I love the way the frame feels so didn’t want to change the sizes or geometry. We have redesigned the yoke to give it a much cleaner finish with an engraved BSD logo. Also, chose some fresh summer vibes for the colors” - Alex Donnachie Read more

BSD ALVX AF+ FRAME


INVEST CAST YOKE

At 12.5" the ALVX chainstay length is as short as it can be. By using invest casting we were able to create a new chainstay yoke which creates more clearance for the tire for when your wheel is slammed. Also because this part is cast and heat treated it strengthens the rear end of the frame by creating a more rigid junction.
