Bottom Bracket Thread Type - this must match the thread of your bottom bracket for the lockring to fit.
Thread Direction - most bottom brackets only have an adjustable cup on the non-driveside of the bike, so lockrings mostly thread to the right (clockwise), regardless of the thread type. However, some bottom brackets have adjustable cups on both sides so the thread direction may be different.
Thickness - this is rounded to the nearest 0.5 mm.

Bottom Bracket Type - ‘square taper’, as the name suggests have square shaped axle ends that slot into the chainset and ‘cottered’ axles are round and secured by pins - pretty much every bike up until the 1990s would use one of these, cottered being the much earlier system.
Thread Type - this must match the bottom bracket thread on your frame. The 3 common thread types on classic and vintage bikes are English (also known as British or ISO), Italian & French, and are usually (not always!) found on frames built in their respective countries. If you're replacing cups, they often have the thread type stamped on one of them, if not there are a couple of things to look at; bottom bracket shell width (English & French = 68 mm, Italian = 70 mm) & drive side cup thread direction (English = left, Italian & French = right). The only curveball to watch out for here, although pretty uncommon, are Swiss threads (also found on some French frames, Motobecanes being one) which will have the same shell width & thread direction as an English thread frame but the actual thread pitch will be different. If none of the above matches what you have, there are a few lesser known varieties that will require some further research.

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.

Extension Length (ctc)* - we measure from the centre of the handlebar clamp to the centre of the shaft, to the point where the stem bolt passes through, to the nearest 5 mm. We always take this measurement in a straight line through middle of the extension, not along the top. In some cases the stem may be stamped with a different extension length as some manufacturers measured differently, but we always use our own measurement for consitency.
Quill Size - the most common size for classic and vintage road bikes is 1", this should be the same as the outside diameter of your fork's steerer column. Oversized steerers found on mountain bikes and later road bikes will be either 1 1/8" or 1 1/4".
Steerer Size (ID) - this is the most important measurement when checking the stem fits your bike. This should match the measurement of the inside of your fork's steerer column, where the stem will be inserted. The standard size for road quill stems was 22.2 mm, or 22.0 mm in France until the 1980s.
Total Shaft Height - measured from the top where the expander bolt head sits, to the bottom of the stem's shaft. To give you an idea of how high the stem can be set, there should be an absolute minimum of 50 mm inserted into the fork steerer, although most stems come with a 'minimum insertion line' to help with this.
Clamp Size - this should match the outside diameter of your handlebars and should be as close as possible to ensure a good and safe fit.

Sakae/Ringyo (SR) Custom-P5 seatpost (or seat pin if you prefer), hailing from Japan and in production during the 1980s. Made from aluminium/steel and weighing in at 289 grams - pretty lightweight for seatposts at that time.

The seat post has 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

Seatpost Diameter - this needs to match the internal diameter of your frame’s seat tube closely, it should be possible to insert the seatpost without force but the fit should be tight enough so it doesn’t just drop in, with no play once inserted. If you have a post that fits the measurement should be stamped somewhere near the bottom, if not you’ll need to measure with a caliper or seatpost sizing tool as the sizes go up in 0.2 mm increments.
Length (Centre of Rails to Base) - measured from where the centre of the saddle rails will sit once installed, all the way to the bottom of the seatpost. Normally there’s a mark to tell you how much of the seatpost needs to be inserted in the frame, however this isn’t always the case so we’d recommend allowing a minimum of 6 cm.
