Stout extra wide WTB bosses on a uni-crown fillet brazed TOUR DE FORCE fork by Steve Potts in 82/83 using oversized Track Tandem tubing at the time.. im Album #ll Proto DIA Cunningham O Potts (MountainTrans & Team Trailmaster Archive)🔧🔗

Not a normal unicrown fork,
Rollercam bosses are not the only thing special going on here, although they are the stouter non Suntour Wtb/Cc version.

For the frame of choice also by Steve Potts, the result will be more than the sum of its parts..

Tandem blades and generous fillets work together to form a crown area which becomes a heat shield of sort by evening out stresses and strain from the ground of what the wheel translates..
