For the split nerds who already have a fresh set of Spark bindings, but just have to have the new Tesla system. Switch the heel loop, ankle and toe straps onto the new base and you are rockin‚ with Tesla (the guy, not the band). Comes with baseplate, Tesla bracket, heel plate, and a bunch of screws. Compatible with 12/13 and 13/14 binding models. Compatible with 2011/12 Blaze and Burner bindings with the addition of the Heel Loop Kit which is sold separately.
