Falkenjagd Aristos CR Rohloff Gravel
The frame, with the reasoning attached to it
The Aristos CR product page says the frame is very stiff for a titanium bike. The number that would back that up — the wall thickness at the tube ends, and why it rules out a second cosmetic weld pass — sits on the materials page, three clicks away, and never appears next to the bike it describes.
This is that reasoning put onto the frame itself. Six markers, each one a decision and what it costs, every figure taken verbatim from 1bike4life.com and linked back to the page it came from.
Every figure, and where it came from
All pages captured 10 September 2026. Where a statement is scoped on the source page, that scope is repeated here and in the panel copy rather than narrowed to this frame.
| Figure | What it is | Source |
|---|---|---|
| 0.6–0.9 mm | Wall thickness at the tube ends Stated for “die meisten unserer Rahmen” (most of our frames) and for the tube ends specifically — not for the Aristos CR alone. | 1bike4life.com/materials#manufacturing |
| Grade 9 (TiAl3V2.5) |
Alloy drawn into their tubesets Falkenjagd’s general tubeset practice. No alloy is stated on the Aristos CR product page. The Aristos SL’s tubes are Grade 5 — do not apply this to the SL. | 1bike4life.com/materials |
| ~3 % Al | Aluminium content held down in Grade 9 to avoid stress corrosion cracking | 1bike4life.com/materials |
| Grade 5 (Ti-6Al-4V) |
Alloy used for parts milled from solid, dropouts included General practice on the materials page, not an Aristos CR product-page spec. | 1bike4life.com/materials |
