Campagnolo did not change their rings when they went from 8 to 9 speed. All 9 speed chain rings are 100% compatible with 6, 7 or 8 speed, 135 BCD crank sets. Record, Chorus, Athena, Daytona and Centaur 8/9 and 10 speed silver inner rings are identical.

Are Campagnolo chainrings interchangeable?

Thus, cranks from Shimano, SRAM, and Campagnolo are freely interchangeable along with those from all aftermarket brands (e.g. FSA, Rotor, Praxis, etc.). And while it is preferable to match the chainrings/crankset to the transmission, there is no strict need to do so.

Are chainrings universal?

They are far from universal, even if you get the BCD and tooth count right. Without knowing more details about the bike/crank/chainring sizes, theres not much we can help you with.

Are Shimano and SRAM chains interchangeable?

Shimano and SRAM 11-speed chains are cross-compatible. If you have a Shimano 11-speed drivetrain, a SRAM chain will work fine and vice versa, however manufacturers recommend pairing your components for optimal performance.

Do all chainrings fit all cranks?

Largely speaking, yes. As long as your attempting to replace them with a chainring(s) designed to work with your chainset. Your cranks will have a specific bolt layout or fitment spec so you cant just fit a BMX chainring to your triathlon bike.

Are all chainrings the same size?

Rings are supplied with different sizes with different amounts of teeth. The more teeth, the bigger the chainring. The number of teeth affects how much effort is needed to turn the pedals. The larger the chainring the more rotations of the rear wheel youll achieve by a single rotation on the front chainring.

Can any chainring fit any crank?

Largely speaking, yes. As long as your attempting to replace them with a chainring(s) designed to work with your chainset. Your cranks will have a specific bolt layout or fitment spec so you cant just fit a BMX chainring to your triathlon bike.

Are all cranksets compatible?

Many chainrings are not compatible across different brands or even across different models for any given brand. Cranksets attach to a frame via bottom bracket, and there are many different types of bottom brackets.

Are SunRace cassettes any good?

The SunRace MX80 cassette is a good way to eek out some extra gear range and bigger granny cog for easier climbing. At 454% the SunRace MX80s range is bigger than the current Shimano XT 11-46t at 418%, and avoids the nasty jump between the larger two sprockets as experienced on the Shimano offering.

Are SRAM chains better than Shimano?

The most durable 12-speed chains. Both Shimano and SRAM can comfortably claim to have improved longevity with their top-tier 12-speed chains versus the equivalent 11-speed options. If the durability of SRAMs 11-speed XX1 chain was impressive, then the results of SRAMs high-end Eagle chains are simply mind-blowing.

Can I change chainring size?

Can I Change Chainring Size? Yes yeah can but you cannot just change your current chainring for something that does not work with your current setup. Meaning the new chainring you get for your bike needs to works with your current chainset. Your cranks will have a specific bolt layout or fitment spec.

How does chainring size affect speed?

The smaller the chainring, the easier the lowest gear for climbing; the bigger the chainring, the faster you can go in the highest gear. You can calculate the gearing ratio by dividing the teeth of the chainring with the teeth of the cog on the cassette.

Can I put a 9 speed cassette on a 7 speed hub?

There are a very few exceptions: 7-speed hubs wont normally accept 8-, 9- or 10 speed cassettes without modification. 7-speed cassettes fit fine on 8- and 9-speed (and most 10-speed) hubs if you put a 4.5 mm spacer onto the body before the cassette.

Are shorter cranks better?

Moving to a shorter crank can improve: Comfort: A shorter crank length reduces range of motion at the knee (extension and flexion), hips, and low back. Aerodynamics: Going to a shorter crank will allow you to ride at a lower back angle which minimizes frontal surface area improving aerodynamics.
