44mm Knurled Headtube


Bamboo Bicycle Club Team

“We’ve manufactured 44mm headtubes as they are super versatile. Suitable for every style of fork, 1 1/8, 1″, 1.5 (tapered) and 1 1/4. These have been specially knurled using the coarsest grade. Despite the additional manufacturing expense it adds considerable bonding strength and longevity to any composite frame”
