Description
Travel cases protect your bike during transit, but they don't solve the fundamental problem of fitting a full-sized road frame into airline-friendly dimensions. The Ritchey Septimer Break-Away frameset eliminates the need for oversized luggage by splitting at the seat tube and down tube, allowing the complete frame to pack into a standard suitcase that meets carry-on requirements for most international airlines. This isn't a compromise design or a folding bike aesthetic—it's a full-geometry road frame with steel construction that happens to separate into two pieces when you need it to.
Ritchey's Break-Away system uses precision-machined couplers at the seat tube and down tube junctions, positioning the separation points where they won't affect frame stiffness or handling characteristics. The couplers themselves are titanium, chosen for the combination of strength, corrosion resistance, and the ability to withstand thousands of assembly cycles without developing play. When assembled, the frame rides identically to a conventional steel road bike—there's no flex at the joints, no creaking under power, and no handling quirks that telegraph the underlying modularity.
The Septimer uses Ritchey's Logic III triple-butted steel tubing throughout, the same material specification found in their traditional road frames. Butted construction concentrates material at the stress points while reducing weight in the tube centers, resulting in ride quality that steel advocates appreciate without unnecessary heft. The geometry targets endurance positioning with a taller head tube and relaxed seat angle that reduces lower back strain on the multi-hour rides that destination cycling trips typically involve....
