Support Calvin Heimburg by picking up a Halo Star Roc3 featuring a new Calvin Heimburg inspired stamp. The "Shark Teeth Clover" stamp was created by Calvin himself based on his own shark tooth collection. Discs may vary slightly from pictures. 

The Toro is a flat, overstable, beadless mid-range that can handle some heavy torque. Calvin Heimburg provided  substantial input in the creation of this reliable, slow-speed midrange.
