Kink Contender II BMX frame – Dan Coller signature, CrMo 4130 | RideHub

The Kink Contender II is the second generation of Dan Coller's BMX frame – strong, precise, and ready for the most demanding street tricks. Featuring a new design with a raised 11.8" bottom bracket and a large 5" head tube, the Contender II provides better bike control and eliminates the need for multiple stem spacers.

The frame is crafted from 100% seamless 4130 Sanko chromoly steel and features reinforced top and down tubes to withstand the toughest impacts. The wide rear triangle accommodates tires up to 2.4", and investment-cast dropouts with chain guides ensure durability and optimal chain tension.
