|The new Challenge Limus|

With the Limus only being available as a tubular, I'll be sticking with the Clement PDX on the clincher set. The side and intermediate knobs are very similar between the two tires but the Limus will have much more bite with it's 3.1mm tread depth and blockier center knobs. Pretty excited to give this a go.
In other news, I've decided that the Shimano C-35 carbon tubulars aren't going to happen this season. Too steep a price tag and honestly I can probably get away without racing on carbon. And should I get tangled in a crash, my pocket book will probably thank me. Instead, I've decided to go hand-built. Starting with Shimano Dura-Ace hubs. I'll probably rebuild them from the get go with ceramic loose ball bearings and use Dumonde Techs liquid grease instead of a thicker paste type. This should create about the least rolling resistance set-up out there. I'll lace them up to Mavic Reflex tubular rims with my trusted and loved Wheelsmith double-butted spokes. My loose calculations will have these 28 spoke gems coming in at around 100 grams lighter than the C-35's and way less expensive too. They'll make a nice match to my Bontrager Race X Lites I picked up this past spring. There's something to be said for the braking power of aluminum rims instead of carbon as well.
What's interesting nowadays is nobody that I found is making a pre-built aluminum rimmed tubular. Guess I didn't check Hed but the big four, Mavic, Bontrager, Shimano and Zipp only make carbon rim options now, crazy.
