We have chosen to work primarily with Aspen, Poplar and Maple as the raw lumber in our cores. Aspen and Poplar exhibit both low specific gravity (weight) and high strength to weight ratio. Aspen is slighlty lighter, Poplar machines cleaner and is slightly stronger, while Maple is chosen for cores where light weight is not paramount but the ultimate strength and "pop" are desired.
Coming in December are Pre tapered cores and sidewalls where the core and sidewall thickness comes pre-tapered so all you have to do is cut your custom ski shape - no more core tapering jigs! We have offered these pre-tapered cores for snowboards for more than 10 years and now we offer them for skis as well!
