Thanks both for your input.
Re the Canyon, the thing is that I really like it.
Re the other questions:
- Tyres: I run Conti 4000s 23mm (105 PSI@70kg), because I have mudguards, can't fit larger tyres
- handlebars: I have the Deda Zero 100 Shallow with normal bar tape. I will try the Fizik gel pads inserts (shall I buy the Fizik kit with the bar tape or just the 4 insert and keep my generic but thick Prologue tape?) Don't want carbon bars as they are too expensive though...
- double bar tape: haven't though about it, will try it.
- saddle: I have the Selle Italia SLR for many years on all my bikes, they are quite comfy...
Thanks again! I will buy the gel for sure.
If SLR is a comfy saddle, well, I´m the queen of england... get a fizik Aliante or similar saddle.
Try the fizik gels, at least on the top part of the bar and below the rubber hoods of the shifters. no need on the drops. It works even better than double tape.
Get rid of crud mudguards, get an sks wider ones and install 25 or 27mm tires. In paris rubaix they use 27, so i guess it will be good for commuting in london too.
The ride will smooth a lot and you will be able to ride much much faster. Also, an ebay carbon bar is around 50€ shipped.
AFTER all this, you can try a carbon frame. i suggest a gran fondo or endurance frame, not a pro racing geometry frame, as that won't help. I would stick to the caad 9 though. great frame.
