I'm guessing disc brakes all round with new models from Trek, Specialized, Canyon & Scott..?
P5X doesn't really seem to be selling that well as far as I can see...so will they for down the Beam bike route, or the wheeled suitcase frame - with hidden compartments for everything..?
Personally, I'd just like something light, lean, nimble and slick looking but also adaptable. Probably more like the Canyon or Speed-concept. I for one have ZERO interest in disc brakes on a TT bike at this stage - I've spent more than enough on fast wheels lately.!
I would like to see the Di2 / Etap junction boxes nicely hidden, but accessible - perhaps on the down tube like the Cannondale Synapse for example?
What I'd really like to be able to do is to 'mould' my own aerobar extensions..!
