I have searched the forum and did not find much on this subject. I am a roadie looking to do a little cross over, nothing too radical just a little trail riding and probably not much more as tearing down a loose rocky incline scares the hell out of me. Would the components be comparable to say a Shimano 105 or better? I like the rear and front travel this seems to be more than adequate. I am 5' 10" and around 200 pounds. Would I be correct in leaning toward the medium frame? I can pick up this new for $1350. Any feed back would be much appreciated.
Whether the components are equivalent to 105 is kinda pointless. But yes, they are good quality parts in the middle of the spectrum. The Deore shifters are sorta like 105: durable and they work well, but slightly heavy and not quite as smooth as the higher-end models. The XT RD is more like Ultegra: excellent quality, price and design, but not as expensive or exotic as XTR (think Dura-Ace). The level goes something like this: Deore, LX (or SLX), XT, XTR.
The components you have are good value, and should work well. I really like the Recon fork too. Nice and light, and will handle your XC applications well.
