Race Face Narrow Wide Chainring for my Trail Bike

My new Race Face narrow/wide chainring has just arrived from bike-components.de. I've ordered this chainring with 34T and red anodizing.
34T narrow wide single chainring weight is about 40-50grams:

 What a great weight reduction! I've thrown away 3 Shimano chainrings with 4 bolts (-200gr), front derailleur (-150gr) and front gear shifter with cable (-170gr).
I hope this chainring will keep my chain in it's place, cause I don't want to use a chain guide.
