With road season on the horizon here in the Northern Hemisphere (they’re already racing Down Under), we are turning more of our attention to the growing list of road bikes on our build schedule. For riders who like to go fast, the go-to material of the last decade has been carbon fiber, and the reason given most is its inherent stiffness. Many of the race bikes we build incorporate carbon fiber in some way, either in the rear triangle, as in our Elium SL, or more extensively, as with our 622 SLX. Those frames can be lighter than a double-butted Ti frame, though much of that difference gets lost once the bike is completely built. Light wheels and/or components make a bigger difference to overall bike weight than the frame.
All of those bikes, the Elium SL, the 622 SLX and the double-butted Axiom SL, have titanium chain stays. We think they make for a smoother, more durable bike than carbon stays, but we have wanted to be able to make them stiffer for some time.
Now we are offering 1″ chain stays that will fit a tire as large as 28mm. These stays are more than 50% stiffer than a 7/8″ stay. That’s a big jump for a small gain in diameter. We are thinking of them as race stays for race days, for our riders who want all the stiffness and power transfer they can get out of their drivetrain, but also want the comfort and durability of a metal bike.
