Ton - my thoughts (on the using it every day thing) exactly. How much per day to stay fit and enjoy yourself...?
CG - up until today (my Tripster's 1st birthday...) it's only really done roads, lanes, tracks and the odd bit of gravel. With some chunky tyres on it loved the stuff I did today. I think I prefer 28c tyres to the thinner 25s that I'd been running through the summer, but if there's a 32 or 38c slick, then I'd look at that too. The 40c Land Cruisers were surprisingly good and oh so comfy on and off the road! It's a hugely capable road bike, super commuter, winter trainer, pinging around the Strava segments - or whatever you throw at it!
With Ultegra 6700, CX disc wheels, 25c tyres, high end Ritchey carbon post and bars, TRP Spyres, Time carbon/ti pedals mine (54cm) was around 18lbs I think. The guards add about a pound, the chunky tyres at least that again!
