Sturmey Archer KB 3 Speed Hub (stamped KB 4) Front hub is stamped "F" "LB 4", 26" wheels, US Chain tires with little to no Treadwear (believed to be of the same vintage. I may have been the only person to ever ride the bike with these tires on it. Internal breakhubs work fine.The US Chain tires 26" x 1.375" alone would fetch over $100. A perfect fit for that Antique Raleigh. All in working order and in excellent condition. Very minor surface discoloring due to the length of time this sat in the attic. I cleaned up the rear hub but did not clean the front one at all. Please refer to the pictures for accuracy. Also selling in related auctions the Sturmey the matching 3 speed shifter and Break levers .
