Kink Nathan Williams Frame Description:

The Kink Williams frame is Nathan Williams' first signature frame from Kink and features modern street geometry while retaining a classic look. Despite the classic look though, the frame features several subtle details that should not be overlooked. The steeper 75.5-degree headtube is responsive, and the short 12.75" chainstay length makes the frame nimble without compromising on tire clearance; fitting up to 2.5" tires. The double-butted toptube and downtube with gussets on both, ensure plenty of strength in the front end while the chainstay and seatstay bridge designs allow for generous tire clearance while adding as much stiffness as possible. Nathan's frame of course comes standard with integrated seat post clamp, integrated chain tensioners, and removeable brake mounts. Additional details like the custom seatstay bridge badge inlay, and interior dropout knurling round out both the good looks and serious functionality of the Williams frame.

My package arrived halfway around the world on time! I've just built up the bike with it and can't do enough manuals and hop whips with it - great so far! The shipping was so reasonably priced too!

My son, Dalton Edwards, loves this frame. He waited a long time and said it was definitely worth the wait!
