High flange hubs were all the rage during the 60s and 70s. Having high flange hubs on your bike instantly adds a touch of retro class to it.
High flange hubs are not just about fashion - they also add to the stiffness of the ride, hence they are used a lot on track bikes. The shorter spokes that are used with high flange hubs mean that there is less flex in the spokes which equates to a stiffer ride. When you're getting your high flange hubs built up onto clincher or tubular rims be sure to get the size of the spokes measured exactly as they are bound to be very different from spokes used with regular hubs.

Taken from the original Suntour manuals-

To convert a conventional derailleur geared bike into an Accushift Plus indexed equipped machine you will require the following essential components:
A Suntour Accushift Plus rear derailleur
A set of Suntour Accushift Plus gear levers and cables
A Suntour AP freewheel or freehub
A Suntour AP transmission chain
Suntour cable stops and guides unless your frame already has these brazed on

All Suntour Accushift Plus components can be mixed 'n' matched so unless you are buying a complete groupset please make the following considerations:
Intended use, touring, racing , mtb etc
Choose a gear mechanism that has a designated capacity within the variation of the teeth on the freewheel and chainrings.
Choose a lever set that matches the number of sprockets on your freewheel.

For accurate and trouble free index shifting certain basic pre fitting requirements must be complied with and the following visual checks should be made on your bike
Rear wheel should align properly in the frame
The chainwheel should be in line with the middle sockets on the freewheel (fit shorter or longer BB axle)
The mounting hanger on the rear dropouts must not be damagedor bent, should have a centre-centre drop dimension of 24 to 28mm and the stop tab should be at an angle of 30 degrees to the perpendicular.
Suntour Blaze and Alpha derailleurs are fitted with a detachable bracket for fitting to dropouts which do not have an integral hanger.

All of these we take for granted these days, everything has to be in exactly the correct place otherwise we know that shifting will be well out. In the early days of index shifting though this was a novel concept with all manner of systems being bodged together!

The manual goes on in much more detail about fitting and then  adjusting the barrel adjuster to get smooth shifting. All this for 6 or 7 gears too! Bear in mind that the shifters were levers mounted in the classic downtube position and still had a d-ring adjuster that meant you could switch to friction mode if your indexing became messed up!

Welcome to the world of Retro Vintage Cycling. Over the coming months and hopefully even years I'll be delving deep into the history of classic cycling equipment and manufacturers resurrecting memories from an earlier time when bikes and their components were made from metal rather than that plastic stuff they call carbon fibre and reliability was a given.

We'll be looking at classic early groupsets from Shimano such as the 600EX and Sante as well as their Suntour equivalents from the time. And no website on cycling would be complete without the leading marque of all - Campagnolo and their offerings such as Nuovo Record and the aesthitcally, if not quite functionally perfect Delta brakes.

Hopefully we will get around to looking at early off road offerings too with a trip down memory lane on the frames that made mountainbiking such as Kona Cinder Cones, Specialized Stumpjumbers and for our UK readers the classic Muddy Fox Courier.

We'll also take a look back at our first bikes such as PK Ripper BMXs, Raleigh Choppers and a whole host of Schwinns.

All the Best
