Hi all, sorry but another (and very specific) tyre width question. Does anyone know what is or, have personal experience with max tire width for 2012 Specialized Roubaix SL3 Pro (rim brake)? I currently run 30mm Schwable G-One speed on Mavic Ksyrium Elite wheels which leaves me I with circa 4mm of clearance on the back, and even more on the front. I did buy Specialized Roubaix 30/32 tyres but they are a fair bit bigger (wider and taller) and do not fit at all. I’m riding on mostly dry maintained gravel roads with a fair bit loose and corrugated sections in North East Victoria (Australia). I’m happy with the Schwables and actually want to transfer them to another bike and if possible, find something a fraction wider for my Roubaix.
Sorry for the long winded question and thank you for reading. 
Hello, I see no one on this platform responded to your question. I have the same question and am disappointed to learn your Roubaix 30/32 tires were too large for frame clearances. Did you eventually arrive at a solution?
