Ritchey TR3 Comp rear hub, hailing from the United States and in production during the 1990s (yet still new & unused after all this time!). Made from aluminium/steel and weighing in at 472 grams. A fine choice for keeping your classic bike authentic, but also great for any other compatible bike.
OVERVIEW
TECHNICAL INFO
Spoke Drilling - the number of holes for the spokes, your wheel rim needs to match the hub exactly.
Spacing (O.L.D.) - the width of the hub measured at its widest point, from the outside of the locking end nuts (O.L.D. = Over Locknut Dimension), not including the hub axle. This measurement needs to match the inside of your frame's dropouts. Steel frames can be stretched or squeezed a few mm but it's always best to avoid this if possible, aluminium or carbon frames should never be stretched.
Speed - the number of cogs the hub was designed to be used with.
Sprocket Fitting - for cassette hubs this refers to the spline pattern (the shape of the cogs where they slide on to the hub) and this must match the cassette you intend to use. With freewheel hubs it refers to the thread, ISO is the modern standard and is almost exactly the same as older English/British and Italian thread, allowing you to mix and match between these thread types as long as it's not going to be under extreme force, in which case it's best to stick to an exact match. Freewheel hubs with a French thread must be used with a French threaded freewheel.
