Steel bike tubing might seem like a simple item, but woe betide the cyclist being flippant with the furnace. All sorts of things, from the intricacies of alloy to tensile strengths and beyond, both boggle and intrigue at the same time; mostly they boggle, sometimes they entertain (repeat after me: "I am not ill"). Reynolds have been creating butted steel tubing in the UK for over a century, and frames built with their very special stuff are ridden, loved and lauded by riders around the world to this very day. To celebrate their unique heritage, Reynolds have released a quirky range of t-shirts based upon previous and popular tubings – 531 and 753. Watch out, we'll be selling 'dem tubes next.
