Good day, I wanted to ask a general question about what ten speed record group, set years where good, not good, or where they all about the same. What do you like and why? I am in Baby Step mode for a older restoration. Thanks!

I believe that there were some chain durability issues during the first year of production. I have 2 road bikes equipped with 10 speed Record and Chorus components. One has Record shifters and brakes, the other has Record brakes. Both bikes were upgraded to Ultra Torque cranks which became available during the last year of 10 speed production. Other than chain, cable and brake hood replacement, both right shifters were overhauled after about 10 years of use. Only thing I would like would be the lower gearing that became available with post 2015 11 speed and current 12 speed

To expand on the previous comment.

You can get just about any compact crank to work if you replace the bottom bracket along with it. That can give you much more human gearing.

Campy made a 12-30 cassette 10 speed, I have one and like it a lot. For me on a compact, I get up and down anything I need to. I do run out of gears on a lot of descents but coasting and tucking is fine with me.

IRD makes a Shimano splined but Campy spaced cassette. I don't have one so can't comment on how well it works but it would give you far more options if you're in the market for used wheels.

Wonderful, thanks I value your thoughts. I am learning and putting together ideas. I am thinking I don’t want to end up with 10 bikes, with each having a different group set.

Are you running the 12-30 cassette with a short cage derailleur? I have the 12-27 cassette, but wouldn’t mind an extra gear at the bottom.

Good day all; I wanted to ask in the Campagnolo Record 10 speed world. Do I need the long cage rear derailleur, to run the larger size rear cogs. I am trying to locate old catalog 2007?? What was available? THANKS;

Power, of the net! I found that a short cage rear, will handle all the Record cassettes. And they made a 13/26 which sounds, rare?

Not rare at all. I have a 13-26 combined with a 52-36 mid compact Ultra Torque crank and short cage derailleur on one of my bikes. Works fine. The other bike has a 12-29 cassette with 50-34 compact crank and a short cage derailleur. That works fine as well.

Use the mid-cage derailleur for more than 26cogs on your cassette. There is a the long cage that was made to best work with Campa triples

I love having Campa on my 10 speeds.



edit: quick pic of Comp Triple from 2004, I think.


the Centaur midcage from same era has about 1cm less distance between the jockey wheels.

There were three derailleur lengths.

Short - 55mm between pulley bolt centers. Officially for standard/compact doubles and all cogs but 13-29. 27T wrap. Or 30T of wrap (2010 OEM manual). 26T (2010 OEM manual) or 27T largest cog. 16 minimum to maximum sprocket difference (which the observant reader will note might get to 13 + 16 = 29 if you don't run out of wrap first, perhaps in situations like 50-39 rings not on Campagnolo's menu)

Medium - 72.5mm between pulley bolt centers. Officially for standard/compact doubles and all cogs plus triple cranks with all cogs but 13-29. 30T wrap. Or 32T of wrap (2010 OEM manual). 29T largest cog. 16 minimum to maximum sprocket difference.

Long - 89mm between pulley bolt centers. Officially for triple cranks and all cogs. 38 (2010 OEM manual) or 39T wrap. 29T largest cog. 22 minimum to maximum sprocket difference. Obviously with the specified 11 minimum starting cog and a 22 range you'd end up with a 33 large which is beyond 29T.

As frames of reference, both the Racing-T triple and standard 12 speed rear mechs are 72.5mm mediums.

The long is very long:

13-14-15-16-17-18-19-21-23-26 is my favorite 10 speed cassette with one tooth jumps through the 19.

Eddy Merckx dominated the pro peloton with a 52x13 big gear and I'm no Eddy; past 30 MPH down-hill it's faster to tuck; and sprinting even 39x14 is a 30 MPH gear.

Conversely, cruising along there are a lot of situations where 17 is big, 19 is small, and 18 is just right.

GREAT, thanks I will put in the build sheet, get it going mode!

IIRC a short-cage RD would accommodate up to a 13/26 cassette (this is assuming a standard 39/53 crankset, so a chain wrap of 27). Moving up to the 13/29 cassette (chain wrap = 30) required a medium cage RD. I ran a 13/26 with a 39/53 for years when I lived in hilly terrain, however I used a medium cage RD because I wanted the option of a 13/29. I ultimately dropped to a 50T big ring which put me into the middle of the straight portion of the cassette for "brisk cruising". I since moved to more rolling terrain and switched to a 12/23 (straight 12-19) and a 51 big ring - there's nothing around where I live that can't be climbed on 39/23, and if I spin out at 51/12, I'm going plenty fast. I have sacrificed a wide ratio range for close ratios and significant overlap between the rings, but that setup works for me. As I age and become more enfeebled, I may switch to a compact (34/50) crankset and a 12/25 cassette - the medium cage RD should still accommodate this (29T) chain wrap.

I am successfully using a Campy short cage with 12-30. That's with a 50/34.

It works. I don't know if it should.
