With his original road bike still fairly fresh, Argonaut founder Ben Farver is already working on an superlight version.
The SL version has a higher mix of hi-mod carbon fiber with a base layer of Kevlar. Farver said the goal is to drop about 80g from the from the frame without affecting the ride feel.
To do this, the first layer wrapped over the mold is Kevlar, which adds a bit of damping since hi-mod carbon is stiffer. It also offers improved impact protection since hi mod is more brittle.
The result is that they can build an SL frame to feel just like a regular frame, except lighter.
It’s mainly the top and down tubes that get the increased percentage of hi mod fibers. They’ll be test riding it through the summer with a possible release in Fall. It’ll likely carry about a $500 premium. Hit that ‘more’ link for detail shots inside the frame…
The Kevlar is the yellow part.
Those little silver bits are rivet ends that fell through the frame during normal construction. No, they wouldn’t end up in your frame.
