I've done 1100 km on my titanium bicycle. I didn't realise I'd done that much riding on it. But in thinking about it, I have done a 230 km ride, three 100 km rides, and numerous other rides between about 20 km and 50 km over the past 4 months. I like the new wheels. Could be my imagination, but the bicycle seems to roll a lot better now.
Of that 1100 km, I've done about 100 km on my new green Brooks ... still a long way to go to break that in!! But it's not bad. I did a 46.8 km on it today and only struggled with the last 5 km or so.
