Chainrings and Spiders

Together, chainrings and spiders are at the core of your bike’s drivetrain, helping transform the force you put into your pedals into energy that propels your bike down the road or trail. Chainrings, like the cogs that make up your cassette, are machined wheels of metal that have evenly-spaced teeth around the outer edge to engage your chain. Spiders, which typically have multiple arms, are what hold the chainring in place on your bike.

Most road bikes have two (and occasionally three) chainrings, with the smaller rings located inboard of the larger chainrings. Most modern mountain bikes are spec’d with just one chainring (known as a 1x set-up), though you will still encounter some riders using 2x and occasionally 3x systems, though the latter is increasingly rare.

Chainrings vary in size and shape. Most are round, but oval chainrings are also an option, purporting to offer more overall efficiency by helping minimize the deadspot in you pedal stroke. Teeth shape also varies, with 1x specific chainrings usually utilizes either a wave or thick-thin tooth profile to enhance chain retention, and lessen the chance of dropping your chain.

Size (indicated by the chainring’s number of teeth) typically run from 26t to 53t, though you find chainrings as small as 20t and as large as 60t in rare instances. The more teeth, and thus larger, your chainring is the harder it is to pedal, but the faster it propel your bike, while chainrings with fewer teeth are easier to pedal, but will not produce as much speed.

So for instance a Tour de France-level sprinter will almost always opt for a 53/39 chainring set-up, while your average weekend warrior road biker may be better suited to a 50/34 due to the ease of climbing it avails. (A 53/34 is typically not an option because the larger disparity in chainring size will produce less-than-optimal shifting performance.)

Another important consideration is chainring attachment, which can be direct mount or bolt on. If seeking the latter, you will need to know the specific number of bolt holes (usually 4 or 5) and also the bolt circle diameter (or BCD).

As you’ve surely guessed by now choosing the right chainrings and spiders can be a confusing process.
