Stronglight A9 headset, hailing from France and in production during the 1980s. Made from aluminium and weighing in at 77 grams - incredibly lightweight for a headset at that time. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.
If you're taking part in L'Eroica or a similar vintage event, this is fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong headset!
The headset's been carefully cleaned, thoroughly checked by one of our mechanics and graded as good condition, but do take a good look at the detailed photos so you can see the cosmetic condition before you buy.OVERVIEW
TECHNICAL INFO
Headset Type - the 1" size relates to the outside diameter of your fork's steerer column which should measure 25.4 mm, if it's 25.0 mm your forks should be French threaded. Although it's generally recommended to match threaded parts exactly, with headsets you can technically mix and match, unless you have French or the obscure old Raleigh threads, in which case you need to stick to that type. If you're replacing an old headset the thread may be stamped on there. Oversized 1 1/8" & 1 1/4" sizes are easily identifiable due to their size and the threads are all standard. Headclip headsets were made to fit fork steerers with 1" or the reduced 31/32" size steerers, as well as 1 1/8" versions for tandems.
Cup Size (OD) - the outside diameter of the cups, this must match the inside diameter of your frame's headtube closely for a good fit. For 1" headsets this should be around 30.2 mm unless you require a JIS headset which will be 30.0 mm.
Crown Race (ID) - the inside diameter of the crown race where it sits on the fork steerer, this needs to be close to the outside diameter of your fork steerer at the base to ensure a proper fit.
Stack Height - the overall height of the headset. To check the minimum stack height you require, measure the length of your frame’s head tube & subtract this from the length of the fork steerer column. You can always add spacers if you have a little too much steerer tube but you can't fit a headset with a greater stack height than the space you have available.

Stronglight Competition bottom bracket axle (or BB spindle if you prefer), hailing from France and in production from the 1970s to the 1980s. Made from steel and weighing in at 153 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.
If you're taking part in L'Eroica or any other vintage event, this is fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong axle!
The axle has been thoroughly checked, cleaned and graded as good condition, but do take a good look at the detailed photos so you can see the cosmetic condition before you buy.OVERVIEW
TECHNICAL INFO
Axle Type - for square tapers, the ISO introduced a standard for European makers in the early 90s, JIS then did the same in Asia. Before then it was not so simple, and although there is a degree of interchangeability, the best way to make sure you have the right axle is to stick to the same brand from the same era, ideally the proprietary model.
Axle Length (D) - your crankset dictates the axle length you need and the recommendation should be used to avoid issues with chainline. If you're replacing an axle that works perfectly then this can be matched, otherwise you'll need to check the manufacturers spec, a good resource for older bikes is Velobase.
Centre (B) - measured from the outside of the 'shoulders' of the bearing races, as seen in the diagram.
Drive Side (C) - the right side (with any logos etc on the axle facing you), your right crank and chainrings will mount to this side.
Non-Drive Side (A) - the left side, where the left crank arm will be mounted.
Shell Width - the width of the bottom bracket shell the axle was designed to fit, measured at its widest point.
