Easton 4-Bolt 11 Speed Shifting Chainring



Excellent shifting even under load, and they look the business too

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

With crisp shifting and nothing in the way of flex, the Easton 4-Bolt 11 Speed Shifting Chainring is a great choice if you are using a crankset with modular Cinch technology.

  • Pros: Great gear changes even under load
  • Cons: No lower gear options for those who like to spin

Designed to work with Easton's EC90 SL cranks, the 4-bolt spider setup here follows the direct mount fitting system found on a lot of modular cranksets. The spider is separate to the cranks, allowing you to customise your gear choices and swap between 1x and 2x setups if the need arises.

The Easton rings come in the usual road combinations of 50/34, 52/36 and 53/39, although if you want to tweak that, the rings are available separately for £42.99 each.

If you want some for a bike that carries a load or use it for audax or gravel riding it would be good to see a 48/32 option, but Easton does have that covered with its EA90 2x Direct Mount chainrings.

Made from Easton's EA90 grade aluminium alloy before being anodised, the rings are plenty stiff enough and thanks to various grooves and ramps on the teeth, shifting is very quick and doesn't become flustered, even when I was trying to make it fail under huge loads.

Price-wise, when looking at similar solutions the Easton version isn't massively overpriced, though it's no bargain. Praxis Works' X-Rings, which work with the Zayante Carbon chainset, are £140 for a twin-ring setup. They do come in that 48/32 combo as well.

Overall, if you want a good looking and stiff set of chainrings for your direct mount chainset, these are very hard to beat.

Tell us what the product is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Easton says, "Building on a strong shifting ring technology platform we went through seven rounds of revisions and refinement with the help of rigorous lab testing and on bike field and race testing with Silber Pro Cycling. The final product is a thing of beauty. Heavily machined for weight savings and excellent stiffness, the Easton shift rings have excellent shifting performance thanks to extensive optimized shift ramps and pins. Utilizing the versatility of the CINCH system, Easton offers spiders with a 45mm chainline optimized modern road bike hub spacing. The EC90 SL crankset is your Easton Advantage."

I found the shifting between rings to be very impressive indeed.
