I know someone will be knowledgable to answer this. I am thinking of upgrading to this new wireless electronic groupset. I want to but as little as possible. I currently have a 10 speed mechanical setup. I need answers to the following:

1.  I have a new Campag Record 11 speed compact chainset. Will the eTap front derailleur work with this so I don’t have to buy an SRAM chainset.

2.  I have Campag Veloce front and rear brake calipers. Will the eTap brake levers work with these or do they use some weird pull ratio.

3.  My rear wheel is a 10 speed Hope Pro3 hub setup. Will I need a new 11 speed hub.

I can’t think of any other compatibility issues. I have resisted going electronic because my frame is a traditional external cabled model. Getting rid of cables is appealing.

Any help or advice welcome and appreciated.

Regarding #3, keeping 10

Regarding #3, keeping 10 speed rear end with 11 speed shifters, it will not work. This VeloNews Tech Fact explains why http://bit.ly/22ipVQI

Yes. Yes. Yes.

Yes. Yes. Yes.

Although Campag and SRAM together might look odd.

And the “an otherwise very mid-level set up” – what? Record crankset hardly screams “very mid level”, notwithstanding Veloce breaks and Hope wheels. Upper mid level maybe.

Also, maybe OP just wants electronic shifting. Maybe he has internal cable routing that won’t take Di2 cables so wireless option is his best bet. Perhaps he’d be delighted with Force or Rival level electronic wireless shifting (I would) but currently option unavailable.

Has anybody done the upgrade

Has anybody done the upgrade yet?

I nearly bought mine this morning, but the shop was sold out within 10 minutes of me receiving a stck alert email… 🙁

10 speed Sram chainrings on

10 speed Sram chainrings on 11 speed set up do work but are not happy.  The angle of the chain in the bottom two gears is such that the chain grinds the outer face if the small chain ring.

Shimming the inner ring inwards messes up the shifting.

Sounds nice.

Sounds nice.

I’m (probably) waiting for medium caged rear mechs, so not sue when they’ll be available.

That’s interesting. Maybe you

That’s interesting. Maybe you could update here when you’ve done your upgrade and it all works happily. I’m hoping to persuade my wife that I need a custom made frame soon, and if I do decide on eTap then the frame can be made super neat with no cable stops for gears.

I’m no bike mechanic Mike, but I really don’t get how this would be an issue. The difference must be pretty minimal, and you would just need to adjust the upper and lower limits.

All of the online reviews are talking about the option of upgrading only the electronic bits (even on non-SRAM setups) and none of them have called out this issue.

Just a word of caution. The

Just a word of caution. The investigations I made suggest that the chainset spacing between outer and inner rings on eTap is wider than on ‘normal’ chainsets, so using an eTap front derailleur with a normal chainset won’t work. That’s what i’ve been told anyway.

If you want to upgrade to an electronic shifting system, why wouldn’t you?

Personally I’m going to do exactly the same to my Ultegra based (FSA crankset) setup. I will probably switch everything over in time, but my bike is only three months old, so will do so as other things wear out. The lack of wires and a big main battery are a huge bonus for me over the other electronic system.

Thanks for all the comments.

Thanks for all the comments. I think the only major stumbling block is the chainset spacing.

I acknowledge the despair I may have cause to any Campag lifers out there. Apologies, I stress at the moment this is just questions.

Also, to the chap who recokns I’m adding eTap to a mid-level setup, if I went ahead with this upgrade the only remaining mid-level kit would be the brake calipers, ahich I’d look to change soon anyway.

The attraction for me is partly being able to have electronic on a frame that won’t take wired electronic, and being a titanium frame I can also have the cable guides removed for a super clean look.

It’s quite an expensive option I’ll grant you. Thanks again to all.

That might be a problem… Wonder if Campag and Shimano also had a wider spacing though? I really don’t know. Definitely worth finding out before you go any further… 

[adrianoconnor]

I really have no idea if that

I really have no idea if that’ll work. My hunch is that it might sort of work, but it’d be a shame if it didn’t work perfectly, and I think there’s only one way you’ll be able to find out for sure if it does or not…

As it happens, I once spent some time planning an upgrade that was going to have a mix of Campag and Shimano mechanical 10 speed groups. I ended up not building it (because it seemed like an expensive experiment if it didn’t work out…).

Anyway, here are my thoughts on your quetsions. Bear in mind that I know nothing:

From what I can tell, Campag and SRAM/Shimano 11 speed cassettes have very similar spacing (see http://www.bikerumor.com/2012/12/12/interchange-shimano-campy-11-speed-cassettes-save-your-wheels/). That means that you could theoretically use your existing Campag 10 speed hub (if it is Campag) to fit an 11 speed Campag cassette (Shimano 10 speed hubs don’t take 11 speed cassettes, but Campag ones should do), and run a Campag 11sp chain and your Campag chainset.

As far as I know, Campag double chainsets have similar spacing between the chain rings to Shimano/SRAM. Obviously spacing is not a problem for mechanical shifters, because you just adjust the H/L on the FD to set it all up. Not sure if etap’s FD has adjustment, but you’d think it would have. It’d be a real shame if it dropped the chain when you shifted down, or if it rubbed.

Brake levers/callipers would work (they might not feel great if pull ratio is much different, though I’d expect they should be close enough), but the biggest problem would actually be that Campag brake callipers don’t have the little lever to release the cable when you want to remove a wheel — you do that from the brake lever, of course. SRAM RED callipers are expensive, but you might find that SRAM Apex or Force callipers are OK for not too much money.

Not sure if that helps or not — I know you were hoping for slightly more definite answers, but I’m not sure you’ll get any. It’s just one of them things. Good luck if you do decide to go ahead!

Also worth mentioning — expect to get a lot of stick from the Campag style police for mixing SRAM of all things with Campag Record 🙂

 Originally I thought yes to

 Originally I thought yes to all until I came across this is from Dan Lee of SRAM: Ten-speed chainrings can be installed on an 11-speed crank, just as 11-speed chainrings can be installed on a 10-speed crank. The spiders are identical. However, all of our groups are designed to function as complete groups, so if a 10-speed crank is installed in an 11-speed group or vice versa, we strongly recommend changing to the appropriate chainrings. Ten- and 11-speed should not be mixed. Our 22 groups actually have the chainrings slightly farther apart than our 10-speed groups, in order to ensure that all cogs can be safely reached in the small ring, and the chain and front derailleur are specifically designed to work with that gap. Running a 10-speed chain on 11-speed rings or an 11-speed chain on 10-speed rings could cause chain jams or derailments.

Whether the aforementioned applies also to eTap your best bet is to get the answer directly from SRAM https://www.sram.com/contact .
