– 10 & 11 & 12 Speed Compatible

  Our rings work with the Sram 12 speed and other 12 speeds. Here’s a breakdown, the differences are minimal and don’t really matter with most components in most applications.  The main difference is the 12 speed chain link plates are thinner so the chain will fit with the 12 speed rear cassettes.  The outer ring is also a little closer to the smaller ring with the mounting tabs being a little thinner.

Here’s a breakdown:

• Chain Width: A 12-speed chain is narrower than an 11-speed chain. The external width of a 12-speed Shimano chain is approximately 5.25mm, while an 11-speed is approximately 5.62mm, a difference of about 0.37mm.
• Internal Chain Width: Interestingly, the inner width of both 11-speed and 12-speed chains, where the chainring teeth fit, is generally the same (around 2.18mm).
• Chainring Spacing: Because 12-speed chains are narrower, the chainrings in a 12-speed system are spaced slightly closer together than in an 11-speed system. This difference is minimal, around 0.35mm, with the larger chainring of a 12-speed system being offset inboard by this amount.
• Shifting Ramps and Gates: 12-speed chainrings often feature more complex shifting ramps and gates to optimize shifting performance with the narrower 12-speed chain.

Practical Implications:

• Compatibility: While a 12-speed chain is slightly narrower, it can generally work with an 11-speed system as the inner width is the same.

Available For The Shimano 4-Arm Cranks

This shift tech is now available for the newer Shimano 4-arm cranks.  They fit great on the cranks with regular road bolts/nuts (as shown in most of the images on this page), but if you want a more finished look, you can also get the bolt covers (by Shimano) as shown in this image to the right.  They cost around forty bucks, and you’ll have to order them from your local bike shop or online, but if you want the look, the covers are available.

This Ultra-Wide 53/34 combination is ideal for those that want the speed of a 53t and the climbing ability of a 34t, it’s the ultimate wide range combination that no other manufacturer produces., a 19t spread versus a 16t from the other manufacturers.

These rings, 53/34 Road combination, fit the newer Shimano 4-Arm Cranks (110mm BCD, road cranks) and are compatible with 10 & 11 & 12 speed chain options. Other mounting configurations are available.  Check out the specs of our many ring options, then get the right rings on your bike.  For setup and maximum performance tips, please visit our technical support site
