I guess Campy is just copying Shimano while it cannot afford proprietary innovations anymore. Road groups always used to have 5 arm cranks since the 70s or so. Early MTB too but then in 110mm BCD (now compact road). Since MTB rings are smaller, it made sense to move to 104mm 4 arm spider, while larger road rings would be less stiff on smaller BCD. For ...

First, I'd trouble shoot why the chain is skipping. Does it only happen under heavy load? Does it always happen in the same place (maybe a stiff link)? Does the derailleur do something funny? If the BCD and bolt pattern matches, stick whatever chainrings you want in there (subject to front derailleur constraints on chainring size + tooth gap). As for if ...

To answer your second question, yes the chainrings will fit. Answering the first question is where things get murky. The issue arises when you look at the distance between the two chainrings, otherwise known as tab thickness. Are those the same? From what I can find out they do appear to be. The 10S chain rings and 11S chainrings are definitely different. ...

You probably don't have to change the chainset at all. An 11-speed chain and front mech will run fine with a 10-speed chainset. A good article by Lennard Zinn who is the last word on mixing and matching drivetrain. 10 / 11 speed drivetrain compatibility Dear Lennard, I was really interested in your recent Tech FAQ columns where you mention ...

A quick Internet search turned up this seller. Looks pricey but has lots of options if you wanted to change your gearing as well. http://www.peterwhitecycles.com/chainrings.asp

It's not the cranks or bottom bracket (though it sounds like the BB might need replacing anyway) if the chain is moving normally. The crank is fixed to the chain rings with bolts, so that can't slip. It's much more likely that the ratchet mechanism in the rear hub is broken. Older ones work on 2-4 small spring loaded "palls" that engage a ramped gear. If ...

Addressing only the technical compatibility, if you currently have a Shimano 8x3 setup, and you wish to upgrade to another Shimano 8x3 setup, then any Shimano 8-speed road parts should be fine. So that includes Claris, Sora, Tiagra etc. as long as it's 8-speed kit. Same goes for the chain. I mention Sora and Tiagra just in case you're able to source these ...
