I've done 290 km on the titanium now, over 3 rides (two 30s, and a 230). It's fairly comfortable, although needs some fit adjustments. The front end feels a bit "soft" or maybe "mushy", possibly a little bit swimmy. I'm thinking it might just be the steel fork, titanium bicycle combination and I may need to get used to that. It's VERY quiet ... even much of the shifting is quiet.
Something else I've noticed is that it climbs well. Yesterday my legs and lungs were struggling to get me up the hills, but the bicycle seemed to handle them just fine ... and faster than usual.
