NDK SPR 02-F3 - NYLON ASYM UNIBACK SET

I got this because BOTH of my carbon highbacks snapped while riding, not spending the crazy amount the carbon replacemnts where. The nylon is cheaper because it is said to be less stiff but honestly I can't tell a difference much.
I wish they had parts more accessible, but they do work well for a replacement on nx2, fuses carbon or nylon.
