Largest 10spd Campagnolo cassette?

[d_douglas]

I am sure this has been discussed here, but I can’t fibd the thread.

I am planning to MX my bike that uses 10spd Campy. It has Centaur with a veloce long cage RD, so I am sure it could handle a 32 or 34 t cassette if it was available.

Are there any cassettes for Campy that get above 29t? The alternative is to go to a triple which would give giant gears but simplicity kinda rules in my book.

For trail riding only, I could use a 34t chainring, but then commuting to work would stink.

Any thoughts?

There was just a thread about this so I know the answer :)

11-30


Also as a bunch recommended on the other thread, you could do a subcompast crankset (46-30 or 48-32) to get that 1-1 or close enough.


oh, I just rememebered this

there is a 32T and a 34T max cassette that IRD makes

[paredown]

There is a 12-30 Centaur but it seems to be a little scarce...

Not sure what you would do to go larger.

[Ralph]

Centaur 12-30. I have one. (12-13-14-15-17-19-21-24-27-30) Last 3 cogs pinned together. It's lighter than a loose cog 13-26 (I know….have weighed them)

IRD makes larger for Campy 10's.

What do you mean by this? Are you planning to run 1x?

If so, just get a SRAM group. You're not going to get the gear range you need out of 1x10 Campy.

[speedevil]

I picked up a 12-30 Centaur 10s cassette from probikekit about a week ago. Was around $70, but I wanted the 30t big cog so that was the way to go for me. I have a medium cage RD, which will handle the chain wrap from a 50-34 compact crankset.

I think that he means, a 34T will give you a lot more space through out the range making flatter rides not as good which I concur.

Ten speed Ergopower work decently with 10 speed SRAM deraillers and Shimano/SRAM cassettes, should you want to run MTB gearing

I have a 12-32 that I have run successfully with both a Record and Chorus long cage RD. I thought I was Campy but just checked and indeed it's not…no idea who made it (arrived on my C40), the lock ring says "GIANG MALAYSIA MARS".

It's in decent shape, plenty of miles on it, and I'd be willing to let it go pretty cheap if you're looking for something to experiment with.

[Plum Hill]

I have a Campy compatible 12-32 made by IRD.

[ERK55]

I have 2 bikes equipped with IRD 32T cassettes paired with Record long cage derailleurs. Works fine. I’ve never weighed those cassettes but they seem a little heavy.

Giang has been making cassettes for quite a while, though it seems that the ones sold in the US are usually branded IRD.
I've installed a couple of their wide-range 10s cassettes for Shimano hubs and had nor heard of any issues down the road in the hands of the bike's owners.
I bought them cash-direct from one of their salesmen, must have been 8 or 10 years ago.

[donevwil]

My wife is running both the 12-32 and 11-34 IRD wide range with otherwise complete Centaur 10 long cage group. They shift well, much better than Miche for example.

Thanks folks! So IRD or Centaur if I want one extra tooth on the big cog?

Does anyone have an IRD in great shape?

@Plum Hill, I think I want the assurance of one with few km vs well used - thanks though!

I think I’ve heard that, but not willing to experiment on this :)

What frame is that? It looks very cool...

That is correct as bad as that may sound. Campag 10s shifters and slam 10s rear der does indeed shift shimano(and spam) 10s spacing..yee-farging-gads!!

Peter, that is just gross. You've been compromised by the Russians?

Joking - but seriously, does this allow me to use Campy shifters with a big gear ratio? Plus, use any old wheel set I want because it is Shimano ?

Yup, done it..it 'seems' to work best with Powershift 10s levers..Centaur and below, 2007/8..Haven't tried it with 2009+ 'Gumby' 10s shifters but I suspect it will.

These shifters ARE also compatible with the long cage Campag rear ders also tho..Racing T, Comp, etc...BUT 10s Campag is closer to ctr cog to ctr cog to shimano 9s cogs than 10s(if ya do this, use a 9s chain)..

But the Campag shifter->spam rear der gig was 'discovered' by Lennard Zinn..he brought a rig by(actually rode over) and let me look at it in the stand..freaky..kinda like dogs and cats living together..Twilight Zone stuff..

Strangely enough..I have used a Campag 10s front ders on 8 and 9s shimano rigs too..'QS' ones..:eek:

[Plum Hill]

Anyone used a Specialties TA cassette?
Looks like a custom job can get a 32 tooth big cog, but pricey.

I had one back in the 9 speed era. They are beautifully machined and shift so well that you could barely tell that you weren't using a pure Campy setup. They wear well for alloy, but that means faster than a steel cog, obviously. I eventually wore out the 15,16, 17 t cogs. I still have the unworn cogs that I can use to make up a hybrid 12-25 with light alloy bigger cogs. Thinking back, I think every product that I have ever encountered from TA has been really good.

Soooo, what frame is this? It has some pretty cool old brakes - love it!!!

This thread has peaked my interest. I have my BMC set up with Jones bars and a 10 speed XT drive train. I'd love to go back to road bars, (Salsa Cow Chippers) and use an old set of Record 10 speed ergo levers to shift a Shimano 11-34 cassette. Will any SRAM 10 speed rear derailleur work? I'm looking at a SRAM GX 2x10 long cage RD. Will that work or should I look for a different SRAM model?

Thanks

Yes, I'm using the Exact Actuation (1:1) GX long cage with clutch with an XT 11-34 and Gen 1 Record 10 levers and it shifts well. Tuning took more patience, but when dialed it's solid. Others will chime in that it didn't work for them, no idea if that's from using the wrong derailleur or some other issue, but in my single experience it works.

As horrid as that all sounds .... could be very useful for some kind of cheap and cheerful monstercross build.

[sjbraun]

Found a SRAM rear derailleur, so I'm prepared to try this amalgamation. I'm trying to make this work with Chorus 10 speed shifters, a SRAM GX 10 long cage RD, and a Shimano 10 speed 11x34 cassette. My crank is a Shimano CX-70, 46x36, working with a similar Shimano FD.

Any thoughts on the best chain to use or suggestions on how to make this work are appreciated.

Thanks

I used an 11-36 Shimano 1080 cassette with a JTek Shiftmate and a Chorus long cage derailleur. Worked perfectly.

I use Campagnolo chains.
It needs more cable tension than the standard full-Campagnolo set up.

[jtbadge]

I'd use a KMC, Shimano, or SRAM chain with a Shimano cassette.

Also, I'd go the whole way and just use SRAM shifters with those derailleurs. But that's not the Paceline way.

[toytech]

I used this to good effect on my old tandem. A local now defunct tandem shop used to set up bikes this way. scrampagnolo:eek:

[Spoker]

I would use this as a guideline:https://www.artscyclery.com/science-behind-the-magic/science-behind-the-magic-drivetrain-compatibility/
Ergo 10 with sram derailleur did not work well for me at all, while Shimergo 9 speed was.

[dddd]

From that chart, the Campagnolo 10s Ergolever pulls only 2.8mm of cable with each shift, versus 3.1mm for SRAM Exact Actuation 10s system.

But also note that there are a couple of typos in those pages, most notably the SRAM 11s Exact actuation cable pull (should read 2.8mm or so according to my research, certainly not the same 3.1mm as the SRAM 10s shifter!).

And this error follows through to the other chart showing the multiplication and the "% difference" column.

And these same pages claim that Shimano and SRAM use different sprocket spacing between their road and mountain cassettes.

And there is also a paragraph that appears to conflate the huge differences in a Campagnolo cassette's separate spacer thicknesses to actual sprocket-spacing ("pitch") differences AND to cable-travel differences which also don't actually exist.

It's just a blog page, so I'm not sure that it's worth trying to save(?).
Those pages were written about 5(?) years ago, are still up on their site, and have never been corrected!

Still, seems like possibly some useful information there, IF you feel you can trust any of it.
