Sturmey-Archer Hubs (which expression shall include spare parts thereof) are guaranteed against defects of manufacture for a period of 12 months from the date of sale providing they are still the property of the first retail purchaser. This guarantee is subject to the conditions specified below.
With all hubs we give a special guarantee instead of the guarantee implied by statute or otherwise as to the quality or fitness for the purpose of cycling of hubs supplied by us, any such implied guarantee being in all cases excluded.
We guarantee, subject to the conditions mentioned below, that all precautions which are usual and reasonable have been taken by us to secure excellence of materials and workmanship, but damage for which we make ourselves responsible under this guarantee is limited to the free supply of a new part in exchange for the part of the hub which may have proved defective, and does not include the cost of [cut off]

A NEW ALLOY HUB SHELL
one-third of the weight of steel
Carefully manufactured from the most modern light alloy and processed by the finest precision engineering in Britain, these new hub shells have been fully tested under all conditions. By fitting an alloy shell a saving in weight of 4 ounces is effected.
This latest refinement keeps Sturmey-Archer where it belongs—far ahead in the field of variable hub gears for cyclists—with a complete range of close, medium and wide ratios to suit all types of riders.
These new shells are now in production and will be available first on the new F.C. and A.S.C. Hubs.

A.S.C.—Medium Close Ratio, 3-speed, fixed gear.

If a defective part should be found in any of our hubs, it must be sent to us carriage paid, accompanied by an intimation from the sender that he desires to have it replaced free of charge under our guarantee, and he must also furnish us at the same time with the date of purchase. Failing compliance with the above no notice will be taken of anything which may arrive, but such articles will lie here at the risk of the senders and this guarantee shall not be enforceable.
We guarantee only new hubs. A hub bought second-hand is not guaranteed by us.

[cut off]BRAKES that make Cycling safe
FM Four-speed Medium Ratio with handlebar ‘flick’ Trigger control, Quick Release Fittings and Wing Nuts. This gear is very suitable for the club rider who requires a gear giving three fairly close ratios and an emergency low gear. Ratios 12.5% increase from direct drive, reductions of 14.3% and 33.3%. An ideal all-round “Clubman” gear.
FC Four-speed Close Ratio with handlebar ‘flick’ Trigger control, Quick Release Fittings and Wing Nuts. This Hub is very similar to the FM except that it provides closer ratios which are suitable in every way for racing. The Low Gear in this instance is particularly useful for making a quick getaway in massed start races. Ratios 9.1% increase, direct drive and reductions of 10% and 25%.

“Flick” TRIGGER
STURMEY-ARCHER 3- AND 4-SPEED TRIGGER CONTROL
FEATURES:
This control has been primarily designed for sporting and racing riders, but it can be used with equal advantage on any Sturmey-Archer 3- and 4-speed hub.
Fitted on the handlebar in close proximity to the grip, it provides an instantaneous change either up or down by the flick of a finger.
On changing up from low gear (by pressing lever down) a positive stop mechanism is incorporated, making it impossible to jump through the next gear. A second pressure in this gear immediately gives a higher gear. In the case of a 4-speed hub, merely press once more.
When changing down, no such stop is incorporated, as there is considerably less risk of missing gear; also it is sometimes necessary to change from top to low direct, in order to ensure a quick getaway.
The pressure required to change gear either up or down is very light and only one finger is required for manipulation.
The lever being placed conveniently to the grip renders it unnecessary to move the hand from the grip, thus ensuring that there is no loss of steering control when changing gear.
The cable is detachable for replacement without dismantling the control, and complete with wires and pulleys, the control weighs only 5 oz.
THREE IMPORTANT POINTS ON MAINTENANCE
1. Change Gear correctly in accordance with our instructions.
2. Check indicator adjustment periodically.
3. Lubricate with R.I. “All-purpose” Oil every fortnight.
