I like the e-13 Supercharger. Its light, durable, and tends to slide over rocks better than alloy. My last full suspension bike had a double ring setup with a 22-36-bash that worked really well and gave me a full range of gears. I've sticked with my triple setup for now on my 29er, but if I were to go to a double, I would probably at least get a 34t for my middle ring.
I want to remove big ring and put bash guard in place.
Will you be seriously bashing it, or mostly just using it to get rid of the big ring?
Unless you need something super tough, I recommend the BBG bashguards. They are cheap ($12 + $4 shipping), light, and durable within reason. I've bought three from Erin and would buy more. They have stood up to the occasional hits off big rocks without any problems.
Thanks for good info. My main reason to get bashguard is for protection and I want to remove big ring since I'm not using it at all. I could keep it and use it as protection but bashguard will look better.
