Outboard Bottom Bracket Cup Sets (British Threading)
We manufacture our Outboard Bottom Bracket Cups for integrated spindle and crank systems from US produced stainless steel and 7075 aluminum. Each OBB cup and center sleeve is machine in-house to the same high-quality standards we apply to all of our products. These cups are only available in British threading and in 68/73, 83 and 100 mm spacing. Our Aluminum OBB cups are available in the same anodized colors and high polished finish as the rest of our products. This allows for a coordinated color match between all of our products.
