There was a few threads about this a while ago and there was no definite answer. Well, yesterday I finally replaced my 'rings and fitted deore middle and inner. It works fine for the middle but you need some spacers for the inner. It caused some issues with my DRS but that's easily solved too.
I just thought it was worth a post in case anyone was still wondering whether you could or couldn't, it's coming up to that season after all. I took some photos, mainly of the issues I had with the DRS if anyone wants: [url= http://www.basquemtb.com/putting-cheaper-chainrings-on-xtr-cranks/ ]HERE![/url]
Bought a Porsche and couldn't afford the tyres eh? 😛
Yeah man, that's about the score of it. More like bought a Porsche when I worked in a nice comfy job with a salary at the end of every month. Now I'm a bike guide, it's the off season and belts are being tightened! 🙂
