Sapelli (also known as sapele or sapeli) is an exotic hardwood from the mahogany family, grown in West, Central and East Africa. It is regarded as the cream of the African hardwoods due its performance, stability and appearance - but also because it is almost completely rot and weather resistant. Almost twice as hard as other mahoganies, Sapele grows with an interlocking grain pattern where the fibers twist around the tree as they grow.  This interlocking pattern acts to cancel out a lot of movement that is typically found across the grain - making it very stable and predictable from the moment it is felled to when it is pulled from a drying kiln.  When quartersawn, the interlocking grain pattern aligns to form the beautiful ribbon striping that is often seen in our bikes.
