Rim: Schmolke Tubular SL30 Hub: Carbon Ti X-hub Road SP Spoke: Sapim CX-Ray Straight Pull Nipple: Enve Internal Brass 10mm Wheel set weight: 1,034g Riding application: Road Rider weight: 67kg Building this set of rims is a huge challenge of my patience. This is probably the most time consuming wheel-set ever built. Here is why. Firstly, for a rim set this light, a washer must be added between the nipple and the rim in order to disperse the tension around the rim holes. Secondly, internal nipples were used. Thirdly, with Schmolke rim, sometimes the rims holes are not perfectly aligned , I had to find the right angle to screw in the nipples. When you combine these 3 into one wheel building process, if you are familiar with wheel building, you know what I am talking about. Having said that, the end product is sensational, super light, perfectly balanced, dished and ready to be glued with some tubular rubbers.
