Sugino Super Mighty chainring, hailing from Japan and in production during the 1980s (yet still new & unused after all this time!). Made from aluminium and weighing in at 97 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike too.
If you're taking part in L'Eroica, Anjou Velo, Velo Retro or another similar vintage cycling event, this is fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong chainring!
OVERVIEW
TECHNICAL INFO
Tooth Count - the number of teeth on the chainring, the higher the number the harder the gear.
Between Adjacent Bolt Holes - the measurement from the centre of any bolt hole to the centre of an adjacent one, if this measurement is the same as that of your crankset and the bolt count is the same then the chainring should fit.
BCD - stands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter) and is the technical way to determine whether the chainring fits your crankset. To calculate, multiply the distance between adjacent holes (in mm) by 1.709 (you’ll likely need to round the resulting number up or down a little).
Bolt Count - the number of bolts securing the chainring to the chainset. As with the BCD, this must be the same as your chainset.
Chain Width - 3/32” is the standard width for double and triple chainsets, wherease 1/8” chainrings are only found on single ring chainsets, generally for track / singlespeed use and can only be used with a wide 1/8" chain.
Intended Speed - the number of cogs at the back the chainring was designed to be used with. We refer to it as ‘intended’ speed as most double and triple chainsets will actually work with different speeds than originally intended, but the further away you get from the intended speed the more likely you are to experience minor setup issues. The exception being some chainrings intended for 10 speed use or higher, with these it’s better to stick to the intended speed.

Sugino Mighty Competition chainring, hailing from Japan and in production from the 1960s to the 1970s. Made from aluminium and weighing in at 116 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike too.

The chainring'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

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 dust covers!
The dust caps have been cleaned, checked 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
Crank Thread - 22 mm is the standard thread for almost all cotterless cranks, the only exceptions are some Stronglight cranks made up until the early 1980s, and Specialites T.A. Campagnolo produced some self-extracting crank bolts with covers that had a reverse thread.

Sugino Autex 4 crank bolts, hailing from Japan and in production during the 2000s. Made from aluminium/plastic and weighing in at 27 grams. A fine choice for keeping your classic bike authentic, but also great for any other compatible bike too.
OVERVIEW
TECHNICAL INFO
Crank Bolt Type - 15 mm hex bolts used to be standard but some older TA, Stronglight and Zeus cranks used a larger 16 mm bolt, plus a few Japanese makers used a smaller 14 mm hex head. Allen key types were introduced in the 1980s and some are self-extracting, which means the crank removes itself when you undo the bolts.
Crank Bolt Thread - All square taper bottom brackets have a standard M8 x 1 mm thread, the only different thread types you’ll find on crank bolts are the much larger M12 & M15 bolts that are specifically for Octalink and ISIS bottom brackets.
£14.88 £18.00

Sugino Mighty bottom bracket, hailing from Japan and in production during the 1980s. Made from aluminium/steel and weighing in at 271 grams - pretty lightweight for a bottom bracket 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 bottom bracket!
The bottom bracket's been carefully cleaned, thoroughly checked by one of our mechanics and graded as mint condition, but do take a good look at the detailed photos so you can see the cosmetic condition before you buy.OVERVIEW
TECHNICAL INFO
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 a bottom bracket the cups should 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 Length - your crankset dictates the axle length you need and the recommendation should be used to avoid issues with chainline. If you're replacing a bottom bracket 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.
Axle Type - you can tell which type of axle you need by looking at the shape of the bottom bracket hole in your crankset. 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.
