I have two sets of Enve wheels. My first set of Enve 45 clinchers and a recent set of SES 8.9s. The 45s billed as the silver bullet lived up to the dream until two years old the rear brake track delaminated. Enve make big noises about heat management but even using their grey brake blocks bad things can happen. I contacted Enve through their website form and sent photos to Info@enve.com……. Three days later and still no reply. There are very few examples of Enve wheels delaminating online and I can’t find a mention of poor customer service from Enve. Perhaps I am unlucky..
