12-36t 29'er-specific cassettes must be used with either M529 (6-bolt) or M629 (centerlock) hubs, which are designed and manufactured specifically to withstand the extra torque load exerted by the 36t low gear
Use of the 12-36t cassettes with other hubs may result in hub-failure and may void warranty coverage
If you can put a smaller granny ring on that triple, that's what I'd do.
I think it has more to do with cya than anything else.
I have been running that cassette on T660 Deore LX touring hubs, Velocity Dyad, hand built wheel set w/o problems on my Origin8 CX700.
On lots of hills, loaded bike, trailer, chariot child trailer, etc.....
I think potential problems would come in to play in the 29'er setting, off road, running a 22 tooth ring up front. Loads of torque possible.
Not what I am doing with mine, though. 39, 50 teeth up front, here.
