Product Description
Did you know that Project 321 was the first to manufacture an adapter for Leftys? Owner and lead designer, Jake Liles believed that the Lefty was superior to many other forks on the market at the time. He wanted the stiffness, strength and weight savings of a Lefty on his Giant AC but due to the larger head tube size that Cannondale designed the Lefty to fit, this was impossible. Temporarily impossible, at least. Jake decided to make this happen for himself not knowing he was becoming the leader of a movement that includes Cannondale now producing their own ‘Lefty For All’ adapter.
This adapter allows use of a clamped crown Lefty on a non-Cannondale frame with a straight 1-1/8” head tube.
Collars are CNC machined here in the USA and the steerer tube is forged for additional strength.
Bottom collar comes pressed onto steerer and is not adjustable.
Top collar is adjustable and moves easily up and down the steerer until it is installed. (Collars must be kept within a specified stack height range: Short is 5.3” – 5.75” and Tall is 5.675” – 6.125”).
