Whether it be hammering down a mountain side, jamming with the club, relaxing through a leisurely ride, raging through a grueling race, or on your daily commute - just spin away, without a worry about the machine beneath you.
Pliant frames make riders squeamish and super-stiff frames make riders bruised.
The right frames make riders free. At Concept Technology, I hand build and fillet braze each frameset. A lot of folks make good tubing. Concept Technology frames have longer chainstays for a more forgiving ride, stiffness in key areas, and tube selection which puts the metal where it ought to be for a smooth, silky ride. I prefer the elegance of lugs, but can't argue against the clean lines of a lugless frameset if that's what you want.
