Over the past 10 years I have ranged from 215 to 305 and was an aggressive rider all the while. I have broken literally dozens of shimano hubs, from Acera to XT. I bought a highly recomended Hope Bulb a few years back. Great warranty, but still broke it twice. I have not made it one season until this spring when I ponied up for the CK HD. Not only is the engaugement fantastic, but with the bolt on rear, the bike felt stiffer as well.
I don't know if you have the same issues as me, but my problem comes from resetting my cranks over obsticals. In the wonderful
pawl system, there is a chance of one pawl catching and with the torque us big guys put out, it will shear it off in now time. The CK eliminates that by design (see their website for diagram). I have looked into the DT swiss or Hugi, I can't remember what they are called now, but they had much less engaugement teeth than the CK. I got spoiled from my 36 on the Hope up from about 16 on Shimano. The CK has 72!
A little more maintenance? Yes, but damn I don't have to worry about riding 20 miles into the woods now. It was almost to the point where I almost carried a spare freehub!
The CK disc HD cost me $408 alone, but damn that is the best money I have spent on my ride so far.
You can also see my reviews under hubs for ken50397. I believe I actually went into more detail.
As far as the chains, I opt for the SRAM as well; you just can't beat that powerlink. I was breaking Shimano's all the time.
Cassettes? I shift better now and rarely have issues with my LX. I did just bend it the end of this past summer, but I say rider error.
I solved my Chain issue. I bought a new SARM and will keep a spare link in my bag.
However, with my added legg strength( see previous post ) I seem to be breaking more parts. I have a Race Face Diablos that is solid as a rock but the rear cassette and freelwheel parts are bending and breaking.
Whne I replace those parts, What is the toughest clyde worthy parts out there????????
