Interesting ... seeing the Red Ribble SLe had started thinking me about my next bike - I deserve another one for my 75th, don't I? - and the Ribble looked like a likely contender. Disappointing to hear about it's harsh ride - you'll have to tell us how you find your Gain when you've been riding it more. I'm running 28mm Conti GP 4000S on mine, and they are more certainly forgiving than 23mm I'm used to on my 'conventional' bikes (in fact the 28mm Continentals measure a real 32mm). Be interested to know how much clearance you get with guards and 40mm tyres. Did you get the bike from Epic?
