Which "XC" parts do you think violate the Proper Nomad Specs ?
#1. The cardinal sin is putting light XC tires on the bike. Should be 2.35" single ply tires or at least a real tacky compound. The Nomad just screams for UST tubeless to help keep it light and invincible. Putting 3" ten pound tires is about as dumb.
#2. Don't put a dinky fork on it either. some people get by on flexy QR forks but the front end will be stiffer and inspire a lot more deserved confidence with a 20mm axel and a nice stiff fork like a 36 or whatever. If you don't mind working a little harder, a 36van or a 66sl are good options. If you don't mind your fork being a little less plush than perfect, then a 36 talas with its travel adjust goodness would be great stuff.
#3. Handlebar and stem. I never had a problem climbing with a short stem and DH bar but I've been in fear for my life trying to descend a steep rockgarden with a long stem with XC race bars. Treat yourself to the best of both worlds for your nomad (60-70mm) but be sure the Bar you pick is still strong enough to handle the activities you have planned for it (nothing scarier than a handlebar snapping.
#4. Hubs and rims. You can ride with just about any setup, but you can save yourself a few hundred dollars by getting tough enough components in the first place. I like the idea of having EX819s on a Nomad, 823s aren't all that much more weight. There are all kinds of hubs that will do the trick. I lean towards Hope Bulbs because they are not that expensive, pretty light, have a titanium driver, and tough enough. DT Swiss, Hadley, King are my other picks.
#5. Shock. There is a reson why DH and FRers use coil-and-oil shocks almost exclusively. Air shocks just haven't held up as well. With new airshocks like the DHX air people are begining to give airshocks another chance. I say DHX air is the bare minimum of burliness for this bike.
#6. Cranks. Some people wouldn't know a pair of stiff cranks from flexy ones even if their life depended on it. I run Shimano Hone cranks on my DJ/urban bike but I'm beginning to think that was a mistake, something is definitely off in there. I have Saint cranks on my DH bike. I generally like Shimano's cranks. I've seen people running XT cranks on DH bikes but I think they just didn't know any better. If I can excersize the demons in my Hone cranks then I would be willing to endorse them but for now I'm just not sure what to do for cranks. A local shop owner has the Raceface evolve DH single ring with 36teeth on his 29lbs Nomad and says that he never has a problem without a granny gear. I would lean towards something like this with a light chainguide. Cranks are a good place to save weight though.
Bottom line is you want to try to keep a nomad light, but you keep it light within a certain range of components. If you really need to hear from the experts on abusable components drop a few questions into the DH/FR forum. If you watch New World Disorder 6: Unchained you get to see Kirt Voreis absolutlely throwdown on his Nomad. That'll give you some indication of what this bike is capable of. You can build a Nomad any way you want, but a Blur LT would work really well if you aren't looking to push the envelope.
