Genesis Croix de Fer vs Salsa Flyway

Both published charts held against each other, on the specs that decide what the bike carries.

The short answer

The Croix de Fer takes the rack path; the Flyway takes tire clearance. Which matters more is your route, not a scoreboard.

Assembled from the differences below rather than written over them, so it cannot drift from the table. Every figure is the manufacturer's; nobody here has ridden either bike.

Where they differ

3 of the 6 things we can compare come out differently. The rest are close enough not to decide anything.

Widest published tire

50mm on 700c / 29in, 51mm on 650b / 27.5in

The frame figure, not the fork's — forks are routinely cut for more rubber than the rear triangle. Loaded, tire width is also seat-pack clearance: a big tire and a sagging pack compete for the same space.

Rear rack

Needs an extra part — Rack-Lock seatpost collar

Read from each maker's own mount wording. An adapter is a real cost the price tag does not mention, and 'not published' is not the same as no — it just is not something to buy a rack on.

Chainstay

10mm longer on the Croix de Fer

435mm
Salsa Flyway
425mm

The gap between seat tube and rear axle, which a rack, panniers and your heels all share. Longer is more room for a load; shorter is a more compact bike. Which you want is a preference, not a winner.

Side by side

Including the rows where the two are level, because a spec that doesn't separate them is still a spec you might be checking.

Drawn to scale

Largest published size of each, built from the charts rather than illustrated. The front triangle is the part that decides frame bag fit.
