Interesting, my road bikes have top tubes of 56.5 and 57 I think. Makes me wonder if theyre too small now, don't really feel it though.
So, first ride on the tempo this am. Smooooth, so comfortable and nice to ride. Good stiffness, even out of the saddle I didn't feel any flex. 28mm tyres and a b17 meant I kept checking for flats! Th front end is a lot higher than I'm used to, which has a downside that I feel very high up and an upside that th drops are very accessible in a way that my other bikes are not. It was only. Horst ride 20 miles of so, but averaged 17.5mph so doesn't look like the taller head tube is a problem...
Spd sl were ok too, easy to flop into but when I missed the clip if got harder as the speed went up! No issues though.
First impressions very good indeed, lots of appreciative looks from other rides too.
