Campag chainring

rochefan

For knowledgeable Campag people: I have Campag Record 11 sp cranks from 2010 and just bought a SuperRecord 53tooth chainring (only one I could find available on the net) which fits perfect but my chainring bolts from the 2010 crankset do not fit. I have another set of bolts for campag (stronglight I think) and they are the same-too wide.
Does anyone know if different chainring bolts are needed for SuperRecord verus Record or maybe the 2010 crankset is out of date and all bolts are of a different size now for Campag 11 sp?
Next question is, any where I can get them?
Thanks

Are these the ones which are nut-less and screw straight into the inner chain ring?

You need something like this:

Note the:

Campagnolo chainring bolts for the 2011 11 speed Chorus, Record and Super Record cranks. These are sold as a set and are only the bolts. The chainring bolts thread into the tapped inner chainring.

Thanks, I didn't know that at all. So it seems I need to get a new inner chainring and a set of bolts or return my new chainring and somehow source a 2010 chainring. God I love Campag!

Are you looking for Compact or Standard chainrings?

Hi

You can't just get and inside chainring and a set of bolts as the drillings in the crank spider are too loose a fit with only the threaded part of the bolt passing through it. You need to source a 2010 or earlier 53T outer ring 11s. Contact us at Velotech Cycling Ltd - we are the main service centre for the UK and Ireland and should be able to help you.

Chorus, Record and Super Record rings are all done this way now ...

This is the first really big change Campagnolo have made in their chainring fittings since they swapped away from all their cranksets being conventional 5 arm designs in 1980s, so it's a bit unfair to criticise them on the basis that they are making life difficilt, especially as they give all of the spares codes for all of the spares at Campagnolo.com, going back to 1996. Two different part numbers = two different parts. If you assume they are going to be compatible ... well, you know what they say about the word "assume".

My criticism is that this is not well known. I bought the chainring from the bike24 and they have no knowledge of this, very few websites stock the chainring bolts and what is very annoying is that I got the 2010 groupset which was not long after they introduced 11sp and then the following year they change the setup, why not do this when they introduced 11sp in the first place? Now there are 2 different versions of campag 11sp chainrings!
The only justification I can see is that it was done to stop people putting 11sp chainrings on their 10sp cranksets.
What way do the TA and BBB 11 speed chainrings work? Will they work on the old crankset or the 2011 crankset? What bolts do they require?

The basic problem here is that Campagnolo do offer one of the best sets of technical documentation out there - but retailers often don't avail themselves of it. Purchasing via the internet often robs the user of the opportunity to ask the right questions, or often for the retailer to ask questions of the end-user, so problems like this occur.

In part to try and counter this, there are publically-available spares listings and exploded diagrams, as well as detailed technical specifications, all downloadable as PDFs from www.campagnolo.com but we find that in many cases retailers, especially, think they already know, so don't bother to refer to them.

I know from colleagues at Shimano and SRAM that they have similar issues. When we deliver training to retailers, we all say the same thing over and over - RTFM ... Read The Flaming Manual ... but all too often it falls on deaf ears. The problem is simply one where even retailers seem to forget that at this end of the market, we are dealing with materials and technology that are at the cycling equivalent of Formula One technology - and servicing and maintaining those products therefore does need close attention to technical matters in a way that it didn't 35 years ago when I started in the industry.

We can supply genuine Campagnolo rings and chainring bolts either direct to the public or to the trade, we hold stocks in the UK and have rapid access to stocks held in Vicenza if we are out of stock - so provided that retailers take the time to check part numbers and understand that a different part number year to year may indicate a lack of compatibility, there should be no great problem in supply. We get a number of technical queries from the public and from retailers daily, and endeavour to answer them the same day if we can as well as running technical training and update courses for retailers - so the information is all out there.

The main importers also generally hold good stocks of the more commonly-requested spares (chainrings amongst them) and their warranty staff in general also have good technical knowledge.

As to why Campag took this course, the modification was made on 2012 series chainsets as the ring itself has changed and been made stiffer to accommodate the demands of the EPS electronic shifting system. If the older 11s rings are used with EPS, the shift system can malfunction - in making the modification to the lateral stiffness of the rings, Campag took the opportunity to reduce the weight and the number of machining operations involved in making the whole crankset. A by-product is an improvement in the shifting of the mechanical system on these rings, too.

I can't comment definitively on other manufacturer's rings, but I'd assume (that word again) that they use conventional chainring bolts. What I really can't say is how effective the ramping and pinning on the rings is, what chain would work on them best or how well they would work with the LH shift lever. They are not direct dimensional copies of the Campag rings so I would guess that they won't shift as well as the OE rings.
