Med Cage Penalty?(8 posts)

Med Cage Penalty?6was9
Jan 13, 2004 6:10 PM
In order to accommodate one of my cassette with 29t cog I have laying around I am thinking of putting a Record med cage rear derailuer. What am I gaining/giving up beside 9g weight diff(from short cage) when I use my normal smaller cassetttes.

A micro milli second of shifting lag as the slightly longer cage flexes just a bit before changing direction and shifting for you. :)

The down side to longer cages is less crisp shifting. At least this is what they used to say in the old days.....

I'm sure now it isn't much of an issue especially with all the stiff light carbon. Besides going from a short to a medium cage is not a huge difference, it is the long cage that normally people worried about in terms of shifting performance.

I'm using a Chorus medium cage and it shifts great w/ a 12-25 or a 13-29.

I have Record components. I've looked a my der. but can't tell if its' a short or medium cage. I use either an 11-23 or 13-26 depending upon terrain. I going on another trip to the mountains this summer and these 41 year old legs would love a it stamped on the deraillerur somewhere?

the distance between the two pulley pivot axles: 55mm = short, 72.5mm = med, 89mm = large.
Thanks. I have a short cage. Too bad.PaulCL

Would 11-23 be fine?6was9

with med cage? Wouldn't the chain be too loose on smaller cog? I probably will be using 11-23 and 12-25 cassettes more than 13-29.

I'm running 11-23 on med cage ultegra and is works flawless, with crisp, fast shifting.
I'm running a tripple and even in the smaller ring and the 11t cog the chain doesnt slack too much. However i REALLY doubt anyone would be running that 34-11 combination. It makes a racket and eats your gears away FAST
