Link below to the 38mm full carbon clincher review. I would like to add that I am very happy with my carbon wheel lineup. I've got the designs where I want them. Since I mainly sell to racers in North America, UK and Ireland, I need durable performance driven wheels my customers can ride day in and day out without the worry of cracking carbon rims everytime they roll up to the start line. I can't stress to you how confidence inspiring this is to know you can trust these wheels when the sh%$ goes down in race conditions. Check out the review.
