Bi-metal powerhouse for advanced players & competitors
The Stubborn definitely falls under the category: no frills, clear focus on performance! The design with 7075 premium aluminum and really fat stainless steel weight rings makes for a great mix of fast playability and long spins that are really enough for the longest combos.
As befits a YoYo of this class, a stainless steel concave ball bearing is of course installed. The response is provided by non-slip silicone pads in the standard 19 mm size, which you can easily buy as spare parts from our store if they wear out.
