Description
The Simplex SX 610 GT rear mech is a long cage touring model from the early 80s and was specced on many a mass-produced French randonneur. With a large total tooth capacity thanks to the long cage and the ability to tackle a 36 tooth large sprocket this is a great way to keep a bike period correct whilst allowing yourself some easier gears. The mech is fitted with Simplex’s direct dropout bolt system which means that it can also be used on bikes with missing, or damaged mech hangers.
