Regina Extra Synchro freewheel, hailing from Italy and in production from the 1980s to the 1990s (yet still new & unused after all this time!). Made from steel and weighing in at 519 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.

These Campagnolo designated freewheels were developed to be used with their 'Syncro' indexing system (sometimes stamped on the rear with a C in a diamond). One of the best freewheels available at the time, they work wonderfully with all non-index (friction) setups too.

▼HELP SECTION

Speed - the number of cogs on the freewheel.

Range - the number of teeth on the smalles and largest cogs, this gives you an indication of how hard or easy the gearing will be, the lower the number the harder the gears. The tooth count of the cogs inbetween are usually evenly spaced, ie: a 6 speed 14-24 freewheel would likely have cog sizes 14, 16, 18, 20, 22 & 24.

Threading - this needs to match the thread of your rear hub. 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. Hubs with a French thread must be used with a French threaded freewheel.

Stack Height - the total height (or width if you're looking at it when installed) of the freewheel, this is measured from the base (back of the largest cog) to the top (front of the smallest cog).

Cog width - this is mainly relevant for singlespeed and some older 3 or 4 speed freewheels - if this is ⅛” then you must use a ⅛” chain, but most freewheels (especially multiple speed ones) will use a standard 3/32” chain.
