Let's see, I just replaced the front wheel on my MTB, used a King ISO hub and Alex TD17 disc only rims with a 185 mm rotor. Rear Speedhub will be laced into one of these rims this winter, but I will stick with the 160 mm rotor in the back. I cut my bars down a couple of weeks ago to the width I was running on my C'Dale, and found out that a wider bar works better with 29 inch wheels, so off to the LBS for a pair of Monkey Lite risers. I stripped the RF turbines off my C'Dale and put the LX back on it, so my 29"er is pretty much right where I want it. I think I'm going to pick up my friend's Colnago Dream, a beautiful Ferrari of a road bike, more bike than I need, but you know what they say about opportunity. Besides, isn't my motto "Don't hesitate, accumulate"?
