It always amazes me how a groupset manufacturer has made such incredible wheels over the years. I rode a pair of Neutrons for 15 years and bar one single spoke break I had no issues and were immaculate until they day I sold them, and I am sure they are still going strong. On first impression, the Zondas are just the same, quality build, hubs, rims and spokes and now a bit more comfortable with the C17 rims. The Zondas in particular are amazing value for money.
