After about 10,000 miles with the Avon Zeon 4XS, I can confidently say they're impressive performers. They've handled all conditions, wet and dry, without issue. I'm not the aggressive type, but I would say the control is reassuring. Differently to some other brands I've tried in the past, ride comfort was noticeably better which makes such a difference on longer trips. I'm planning to buy another set when the time comes.
