I’m buying a complete Campy Veloce group set from Ribble for my wife’s bike and I’m unsure which rear dérailleur to get. I don’t know the difference between medium and short. It’s to do with the rear cassette, I know that much, and I’m assuming bigger range (13-29) would require the medium one?
Dumb question I know.
the longer the derailleur cage the larger the difference in teeth # from high->low gears it can handle (this also includes the chain rings - but on a road crank that isn’t usually an issue), i.e. a MTB derailleur vs a short cage road.
I don’t know much detail about the Campag stuff, but if you want a good spread of gears go medium.
Cant find the manual to confirm, 29t would almost definitely want the medium cage. if you dont get an answer I’ll report back after I get my little one off to bed.
Get the medium. A short cage MIGHT work with a 29t rear, but medium will defs work.
Also, veloce is a sweet group.
Cool. Thanks for the confirmations.
The BB cups are sold out in Italian thread, so we have to wait til they’re back in stock.
For a 13-29 you’ll need a medium (longer cage) derailleur. 13-29 is a great range of real world gears 
That’s my wife: real.
I might have a set of Italian BB cups laying around if the ultra torque cups work that is…
Defantly get the medium cage… Short cage isn’t done in the 11 speed range at all… It was a 10s thing to offer different cages. I have a nice 11 speed partial gruppo In wife
friendly 170mm cranks and compact for a simlar price.
Only thing is then she’d be rocking way more passion than you…
Not to derail the thread but I wish shimano/sram made such a cassette available- I mean how often (if you aren’t racing) do you really use an 11 or 12?
^ nice.
In all seriousness, I use my 53-11 daily haven’t you heard of comuter cup?
That’s a bigger gear than many of the entrants in the Kilo event at Hisense Arena this weekend. Either you’ve got super legs or haven’t as yet learnt how to spin.
I’m a big fan on the 11t
I only run 50-11 and some times on Anzac prd trying to ride down the Beardy one Marcus it’s not quite enough.
Might get semi compacts when they come out, 52,36…
Im good at spinning. The reason I went compacts was to learn to spin better. But if you think the 11 is too bigger gear your not riding fast enough…
Huge referred to needing his 53 x 11 on a commute. That’s ridonkulous.
I’ve been mixed up in the commuter cup once or twice coming home from or to the city at the wrong time of the day…
It’s like bringing a f1 car to a Mx 5 cup race… Pretty funny
Your right though Spirito commuting… That’s what my sweet fixie is for…
As long as the cassette goes to 29t, I reckon a traditional 52/53 is a good thing to have. But Melbourne is flat.
My beef with the 50/34t compact is not so much the 50t but rather the too low 34 small. In my experience it was hard to find the right ratio at cruising speed.
Something like 52/36 would ideal
^ stuff that H. JLN is in Adelaide. Adelaide has big hills. A compact would be perfect. He can always swap out the 34 for a larger ring further down the track if need be. I doubt that will happen.
You can get a 36/50 compact. It’s a fairly good compromise.
The later, however when I take the road bike on my commute I can hit over 70 km/h for a stretch of road and have another 2 k section that I average over 50 km/h.
Spinning gets my suit sweaty;)
Skin suit?
You must be spinning some as that’s about a 126" gear (53t x 11t with a 23c tyre) and 70km’s means you’d be doing just over 115rpm. That’s hauling. I can turn the big gears but my commute is a lot slower due to traffic, conditions and other cyclists who are the biggest danger.
The 52/36 combo is the new semi compact set up, it makes heaps of sense
I can’t wait for the praxis version for my bike…
That slight increase in top speed will be ace.
