Campag mid cage question
Campag mid cage question
Postby MountGower » Sat Jun 07, 2008 5:27 pm
Does anyone know of any problems I may encounter if I use a mid cage Campag rear derailleur with an 11-25 rear? I am ordering a Centaur groupset with 13-29 so will get a mid cage derailleur with it. If in future I decide to go 13-26 or 11-25 I can't see any problems but thought I would ask before I buy it, incase I am overlooking something.
Also does anyone feel strongly that I am better off with a CT front set up rather than the big rear?
NB: Getting out of the saddle at 70kph and sprinting doesn't interest me. This is about climbing the back side of Mt Mee or Mt Gorious with 160km or more already in the legs.
Thanks in advance.

One web page I found very useful for playing around with 'what ifs' is Sheldons gear ratio page which I'm sure you've already got book marked

How far does it go?
Won't be long before you have to replace the 2.8mm, 18x, $250 chain every 500kms

I was in a silmilar boat (although with Shimano and already a short cage RD). I am looking at going the Compact front to enable me to climb hills.
The rear cassette is 12-25, so will spin out down steep descents, but meh ? Can easily put on a smaller cassette as the fitness improves or go to larger rings on the front as well.
For me, a much cheaper option and easy to boot.
A 12-27 cassette didn't quite give me the bailout gears I wanted.
Lotsa work to be done on the engine as well ....

I would have been happy to stop at 9.MountGower wrote:Do people want it? That's the question. The reading I've done suggests people think they don't use the ten they've got. It does seem a bit silly. To me anyway.
I mean 10 lets you run 11-21 with single tooth gaps, or 11-25 with mostly single tooth gaps. I don't see the benefit of turning one more 2 tooth shift into a single tooth shift.

In fact, I have chosen to stop at 9 - now I just hope that I have spares / service coverage for the next upmty (unless something nasty happens to me) years.
I realise that I face having more 'multi-tooth' changes than 'single-tooth' ones on just about every cassette I use, and that those changes aren't quite as smooth.
I haven't ridden enough to be able to comment on the relative life-span of 9- vs 10-speed components.
It must be the 'old phart' in me - I just like the idea of an odd number of gears and polished alloy.

10 is a nice round number and I'm sure people go for it because it's a logical number of gears to have.
11 isn't, I don't think they'll be able to sell the benefit of one more gear.

Or there are no alternatives. If you want Campagnolo 9-speed these days its a trawl for NOS.Bnej wrote: 10 is a nice round number and I'm sure people go for it because it's a logical number of gears to have.
They don't have to really. Sure you can stick with your 9-10 speed if you want to, but if you want new gruppo to go on your new frame (or some such) you're going to have to go 11-speed. Rumours/reports are that all three top-end Campagnolo groups (Record, Chorus & Centaur) are going to be 11 speed.Bnej wrote: 11 isn't, I don't think they'll be able to sell the benefit of one more gear.
