The latest addition to the Grand Tour range, the Grand Tour 46/30 is a sub-compact double crankset designed to be both beautiful and resilient. Every component including crank arms, chainrings, pins and fixings are proudly made in Britain using the finest materials, including 7050 and 7075 grade aluminium and 316 stainless steel.

All of the Chater-Lea cranksets are anodised to enhance protection.

PVD Coating:
Physical Vapour Deposition (PVD) is a process utilising powerful magnetic fields to apply an extremely uniform and ultra thin coating to a component. Chater-Lea's PVD coating is a super hard, corrosion resistant layer of Titanium Nitride around 2 microns thick. The PVD process vaporises the Titanium Nitride allowing it to be electrically applied to the component with extreme adhesion. It is in fact nearly as hard as sapphire, itself second only to diamond in hardness.
