Shimergo or Will my x speed shifters work with a y speed mech and a z speed cassette?

@avymtal

Checking in: nearly 10k kms on my C10–>S8 and going strong.

10,000km’s !!! Bravo !!

Pro tip: commuting is where the big k’s are at.

[dallimor]

It will take me about 8 years of commuting two and from work each day to get to 10,000km

Since April last year for me…

Ok, so I’m running a shimergo setup on my Voodoo - 10-speed Ergo shifters to Campy 9-speed double front and Shimano MTB 8-speed rear. Also running V-brakes with travel agents. It’s sweet.

But, I’m now considering having a full MTB front I can swap out on occasion: front shocks, front disc, flat bar with MTB levers/shifters.

Can I now go back? The rear will be fine with 8-speed MTB shifters. And I could find a short-pull flat-bar lever for the rear brake so I don’t have to remove the travel agent each time. But what can I use to shift the front (it’s a current 9/10spd Veloce derailleur with a 9-speed Campy triple-turned-double-with-bashguard crankset)? Am I limited to having a bar-end shifter for the front?

Also, is there a simple clean way of being able to swap out my rigid forks and drop bars to shocks and a flat bar, with the associated change to shifters/levers, without having to use (and set up) a second set of cables for the rear brake and derailleurs? Could I use a cable-splittler a la S&S coupled travel bike?

Blakey what’s the answer!?

(I’m suspecting it is: “buy another bike”)

Thanks for all this Blakey, this is great. Agreed that quote is a huge call, somewhere else they temper that call slightly, saying that their method is good for Shimano/Campag/Sram but not sure for others. Worth a go in my case as I want to stick a Shimano freehub body on a Campag hub. I’ll report any success/failure

Report: failure. Took me some time to try this out cos #dadlyf and other things, but now I know that a Deore hub does not take a Campy Scirocco freehub body. Not a problem, I gave my Shimano hubs a good cleanup and reconciled myself with using those wheels, even though they’re heavy as.

Can’t say I’m surprised!

Cool. Ta.

[swuzzlebubble]

Any chance an Ambrosio Campy freehub will go on to a Gipiemme Shimano wheel (10sp)?

[AL9000]

No idea, sorta unrelated to the mismatched drivetrains that this thread is about. Compare the two (photos / IRL?) and see if the dims and interfaces are the same perhaps. Doesn’t sound as easy as campy:fulcrum.

But that reminds me to post this:

EQUAL PULLEY!

The red one just saves you having to run hubbub cabling, so… waste of money unless you want to use a 9sp shadow mech? And the gold one lets you run a 10sp shimano RD with 11sp campy levers and 11sp shimano cassette, but the stack of campy and shimano 11 are basically the same, so why not run the levers with a C11 RD and it’ll be fine on the shimano 11 drivetrain…

The fact that both 2015 and pre-2015 levers use the same pulley indicates that the cable pull is the same, but all the literature says they changed the pull (UK campy tech over at WW reckons they ran tests and they’re not compatible.). Which is real…

Well, I’ll have a mismatched drivetrain if I can’t swap it over

I have read the same Blakey,
Main difference is the geometry of the rear parallelogram mech, longer front mech cage and different shifters.
So what your saying is the internals run the same part numbers?

I’m sayin that the EA PULLEY people seem to think that their conversion piece works the same with pre 2015 or post.

So either they’re wrong, and one of them doesn’t work, or they’re right and the change in pull is within the tolerance of the floating upper pulley on the shimano mech.

Makes C11-S10 or C11-S9 shimergo tough if supply of pre 2015 levers dries up and the 2015 ones don’t play nice.

All of this ignores the front shifter, they don’t mod that, but 2015 on would probably work well with a 5800/6800/9000 FD as they both have longer arms.

New 2015 Campagnolo Front Derailleur - Weight Weenies

@Graeme

We can confirm absolutely (because we have tried it …) that 2015 shifters are not compatible with pre 2015 mechs, F or R.

We are currently fragging shifters to see which parts are interchangeable, as is our habit - we are one of the few businesses that still sell all of the individual parts of UltraShift shifters (because we break down full shifter bodies to make this possible).

We can also confirm that 2015 hoods are differently lugged on the reverse side to pre-2015 hoods and they are not interchangeable. If the lugs are trimmed off, they move about too much on the lever body and can cause snagging on levers 2 and 3.

There are some similarities to QS in terms of different action but the key thing is that the gate in the derailleur cage is very different in profile and the inner and outer cage plates rum much closer to the chain in a correctly set-up system. This massively reduces the chances of over-throw (especially to the inside) even at high applied torques and low cadences.

Torque at the chainring can be significantly higher (double-figure percentages in the case of the 50-34 and 52-36 combinations) at the same shift success rates against the 2014 version, provided that the 2015 chainsets and rings are used. We have factory data as well as direct experience to uphold this.

Performance is slightly improved with pre 2015 chainsets but not significantly so other than in the case of SR RC and later 2014 OT chainsets that use the RC14 rings … these chainsets appear to give a sort of half-way house improvement - this is from our tests not from factory data - we assume this is as a result of the ring spacing being slightly different in 2015 chainsets.

One of the key advantages of EPS remains the front up-shift performance, provided the FD mounting is rigid and durable enough to allow that force to be applied - it still out-performs any mechanical shift system available at low cadences and / or high torques at the chainring. The applied force at the chain available is almost double what an average rider normally exerts on shifting and this is one of several factors that affect front shift speed, accuracy and success rate. 2015 mechanical is very clearly better than pre 2015 but still not up there with EPS.
