Gearing Help

Hi all,
I have got a SRAM Rival 46/36 chain set that I am going to pair with shimano rs685 shifters and 105 front and rear mechs.
For the rear which cage length should I go for? I like the look of the 11-32 cassette or is that over kill? Would I get away with a short cage length due to the 46teeth on the front?
Thank you

If you are then I'd stick to an 11-28 with a short cage rear mech. If you went 11-32 you'd have to get a long cage rear mech and they attract more mud and grass than a short cage. To be honest if you can't pedal a 36/28 then you'd be better off running.
Yes you will be fine with a short cage with a 46. My set up is 46/36 and 11/28 and I run a 105 5800 short cage rear mech.
That said, rozzer's point about the short cage mech is a good one. Since 28 is the limit with Shimano, I'd go with that and consider a smaller chainring (compact will go down to 33) to get lower gearing.
Alternatively, have you considered a single chainring setup (keeping the remainder of the existing chainset)? Less weight, less to go wrong, and far superior mud clearance...
No plan for racing yet, will be for training and hitting the local bridle ways for fun.
I will see how I get on if I get into it I will give one of the cx sportifs a go late this year and see how I get on from then on.
Already planning so big cross country rides later this year looks a lot of fun.
I ride compact with 11-28 on the road bike and I have got a 11-34 on the mtb.
It's pretty hilly around me and my fitness is poor atm! I am thinking of going 11-28 on the cx
