Every ride...a flat
Hi guys, I live in Boca Raton FL and ride along A1A every Sunday for 4 years since my move here. I ride Cannondale Bad Boy Ultra on Vittoria Randonneur Rigid Tyre, Full Black Reflex, 700 x 28c.
(about 1K on them) and about 2 month ago, I started to get flat tire every time I rode. After couple of flats, I brought my bike to a shop and they replaced an inner liner on my rear wheel (only rear tire got punctured so far)
Next Sunday ride, flat again. Got an outer liner on my rear tire, guess what happened next ride...flat. When replacing tubes, I usually go with my hand thru the inners of the wheel to find something that punctured, nothing to be found, Was suggested to replace my tires with Gatorskins. Thinking of doing it. But for now...
So my questions is, what can cause those punctures? Any suggestions based on your experience? Thanks in advance.
