It’s 1934. Antonin Magne is training in total secrecy. On his bike are the first-ever rims made from duralumin, an alloy of copper and aluminium.To keep this brand-new technology under wraps, the rims are painted to look like wood.They’re called Dura rims. They’re our invention. And they weigh 750 grams rather than the usual 1.2 kilos
