Cyclocross and Gravel chainrings made for Shimano 4-bolt road cranks in a 42/34 tooth combination with BRIDGE Shift Technology.  These are the same tooth count and shifting configuration made famous by Katie Compton in the 2013-2014 World Cup domination — now configured to fit the newer Shimano 4-bolt road cranks.

Specifications:  Note:  These are now all black

BRIDGE Technology Cyclocross & Gravel Chainring Set:

– 42/34 Teeth
– CNC 7075-T6
– MIL Type 3 True Hard Anodize
– Weight 113g (Ring Set)

Compatibility:

– Fit for Shimano 110mm BCD, 4-Arm Road Cranks (see image below)
– Note the 4-bolt non-symetric mounting
– 10 & 11 & 12 Speed Compatible
– Fits Dura-Ace, Ultegra, 105 and others with this bolt pattern.

  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.

Cyclocross and Gravel chainrings with BRIDGE technology – made specifically for the demands of ‘Cross.

42t Cyclocross & Gravel Chainrings:

The 42/34 tooth chainring combination by WickWerks was made famous by Katie Compton as she dominated the Cyclocross World Cup in the 2013-2014 season.  Her choice to go smaller rather than bigger bucked traditional wisdom but propelled her to many race wins and the overall Cup!  This 42/34 tooth combination is now available for everyone — and this specific set — is made to fit the newer Shimano 4-bolt road cranks.

These are high-performance chainrings made with BRIDGE technology to shift faster, shift more dependably, to give you the race and shift advantage.

Check out the chainring images above and note the back view with aggressive chain ramps.  (We call it BRIDGE Technology, and it changes the game.)  This is the best shifting currently available — miles ahead of shift pins.

WickWerks BRIDGE shift technology is a favorite in cyclocross racing circles because of the shift advantage.  Now it’s available here in a 42/34t Cyclocross combination made for the newer Shimano 4-bolt road & CX cranks.

Shimano 4-Arm Cap Covers

This ring combination is designed to fit the Shimano 4-Bolt Crank, 110mm BCD, road cranks, and are compatible with 10 & 11 speed chain options.  Though the rings work great on the crank alone, if you want the finished look, you can (purchase separately) the special cap covers that Shimano makes for this Crank (shown in the image at right).  Be warned, they are expensive, but if you want them, they are available.

Other sizes, like the 44/34 combination are also available for the Shimano 4-Bolt cranks — as well as other mounting configurations are also available.  Check out the specs above and get the right rings on your bike.  For setup and maximum performance tips, please visit ourtechnical support site
