So the weight weenies here at Sage Cycles and BPX as the premier Scott Bike Dealer in San Antonio, are stoked about the super legit New 2012 Scott Spark RC 29er HMX Carbon bike announced at least weeks Interbike. We ordered a bunch of them, I personally ordered a frame to build up as I like. So, I am starting to do research into the best bicycle parts for a lightweight build to match to this awesome frame. I am starting with the wheels. Some of the interesting ones on the market today are the Easton EC90 XC Wheelset and the ENVE 29 XC Wheelset. Clincher or tubular? What comments do you have on carbon 29er wheelsets? What works?
