Hey everyone, I'm building up a 1x10 air9 and I need some input on derailleur choice.
I'll be running a 32 front ring with either a 11-32, or 11-36 10sp cass.
Do you think a short cage would work with the 11-36?

Thanks!

Yes. The only advantage of the med-cage is if the future you want to move to a double setup, you wouldn't have to get a new rear der. Get the 11-36 cassette if there are anything resembling hills near you. I have a 9sp 32t front ring with 11/34 rear on my Jet9 and wouldn't mind a slightly lower gear to bail to at times. It will also give you the option to go to a 34t front if the 32 feels too easy.

I'm doing a 1x10 setup on my Jet 9 too, and I was thinking short cage is the way to go ... have you heard any negatives relating to short cage, other than it won't work if switching to a 2x10?

Thanks

I'm running a 34T up front and 11-34 in the back with a Sram X9 short cage. Shifts great.

1x9, 1x10, etc. formula is largest cog on the cassette minus the smallest cog. In your case, 36-11=25.
Your derailleur only needs to have a 25 tooth capacity. Sram short-cage can handle up to 30. Shimano med cage can handle up to 33.

Get on...

im going 1x10, but was thinking medium X0 ( purely as i already have one....) rather than short because, it will allow the extra chain slack from changing between the 34 and 36t chainrings im gonna use this year....

Any limit to the front ring size with a short cage? I'm assuming shifting in the rear should be smoother/crisper with short cage versus medium or long ... is that right?
