About a month and 500 miles ago, I took delivery of a CX1 from my friends at Velo Pas. This is a sloping monocoque frame with an integrated headset and slightly oversized tubes. Not your standard fare from the Italians as it is constructed in conjunction with Giant. No matter. This is one well designed and finished frameset.
Light. Record 10, Shamals, Newton bars, Time RXS pedals and Arundel cages. 16.25 lbs. This is the same frameset that was built to 12 lbs. with Red at Interbike this year.
Stiff. At 145 lbs. everything is stiff to me. But I could see where a bigger rider would have trouble putting the flex on this. What I put in is little wasted.
Soaks up the vibration. Indeed. Up and down the 150, Casitas Pass, and Mt. Hollywood with less of the jarring I normally would expect of that terrain.
Responsive. Oh yeah. Every once and while you hit debris with the rear wheel in a down hill corner, the wheel loses contact and you're forced off line to regain control. Not with this frame. It sticks the line in a self correcting fashion. If that's not the right terminology, forgive me. But, this just sticks to the plan. Rocks or not.
Price. I would expect a frame of this quality to be more expensive. But, the crew at Velo Pasadena passed along a very good deal. And they have done everything to insure the fit is right and all adjustments are correct.
I would say if you're in the market for a carbon frame, check out the CX1.
