I bought a new Freehub Body when I started hearing a weird clicking noise coming from my 2009 Mavic Ksyrium Elite wheels. The plastic bushing was worn from age. Ordered this hub body replacement instead of trying to replace just the bushing, as I didn't want to risk damaging the splines inside the old hub body. The install was easy and my 2009 wheel feels like new!
I am an avid road cyclist with an annual average 9000 miles. I am impressed with the traction of this tireduring rainy conditions. It corners very well and I can get about 2000 to 2500 miles on them (nothwistanding abrasions from road debris) I was a big Michelle's fan until these came along. Love how they work well together with the Mavic wheel system
