Esker Hayduke vs Trek Farley 5

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

The short answer

The Hayduke takes frame bag space and price; the Farley 5 takes tire clearance and fork cargo mounts. 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

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

Frame bag space

156 cm² more on the Hayduke
Esker Hayduke
1745 cm²
Trek Farley 5
1589 cm²

Front-triangle area at the largest size, computed from stack, reach and seat angle. It is what decides how much full-frame bag you can run, and a frame bag is the one place weight sits low and central.

Widest published tire

38mm more on the Farley 5
Esker Hayduke
76mm on 700c / 29in
Trek Farley 5
114mm 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.

Fork cargo mounts

only the Farley 5 publishes somewhere to bolt a cage

Cage mounts on the fork blades. This moves weight low and off the bars, which is where a heavy bar roll does the most to the steering.

Chainstay

10mm longer on the Farley 5
Esker Hayduke
440mm
Trek Farley 5
450mm

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.

Manufacturer's cheapest complete build. Every spec above belongs to the frame and does not change between builds of the same model, so the cheapest build of the right frame is usually the right answer.

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.

Esker Hayduke in size S4/XL, drawn to scale from Esker's published geometry. The shaded area is the front triangle — roughly 1745 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.
