Chain rings/crank sets

[Eugene]

I know that wheels are brand specific (either Campag or Shimano). Does the same apply to chain rings?

 

I noticed on a particular online store that when purchasing a crank set there was no option to choose between Campag and Shimano type drivetrains.

 

I have also seen a bike that had a Sram Red groupset with Campag Centaur cranks.

Any cranks with with any goupset. That's why brands like Cannondale have their on cranks and 3rd party manufacturers like FSA, Rotor and Zipp.

 

 

 

When you buy a groupset, you can not choose another brand. Sometimes you can choose not to take a crank at all and then take a third party one.

 

 

 

The rings are another story but I think you can put Shimano rings on Campy arms as long as the bolt pattern fits. I can be wrong in this aspect, I've never tried it.

The rule is: if it fits, it works.*

 

 

 

 

 

*Exception: Q-Rings may not work as promised irrespective of whether it fits or not.

Shimano and SRAM is 130 PCD (bolt circle) for the road and Campagnolo is 135 PCD

and compact cranks use 110 BCD. <?: prefix = o ns = "urn:schemas-microsoft-com:office:office" />

 

PS: MTB cranks use a different BCD and usually one spider arm less.

<?: prefix = o ns = "urn:schemas-microsoft-com:office:office" />

 

PS PS: Track bicycle also use a different BCD (144).

And then there is the new system that uses all-steel spiders octopusses (octopi?) with a Zero BCD.

On my downhillbike I use a slightly larger chainring.

Some of the older MTB cranksets use a 5 bolt 94mm or 110mm BCD
