MTB Saddle Finder

Cranky MTB Fit Tool

Find the right MTB saddle

Choose a saddle based on sit bone width, riding style, e‑MTB use, pressure issues, weight preference and rail construction — not guesswork.

How to measure your sit bones

Your sit bone measurement is the distance between the two bones you sit on. It is not automatically the saddle width — the finder adjusts the recommendation based on posture and riding style.

1

Place corrugated cardboard on a firm, flat surface. Avoid soft couches.

2

Sit upright and load your weight firmly onto the cardboard.

3

Stand up carefully and find the two clearest impressions.

4

Mark the centre of each impression and measure centre-to-centre in cm.

5

Repeat once if the marks are unclear. Use the most consistent measurement.

Construction guide

Saddle rail and construction basics

For MTB and e‑MTB riders, saddle durability can matter as much as shape. The finder considers rail material, rail shape, rider weight, seatpost compatibility and how the saddle is loaded.

Steel / CroMo

Usually the safest value/durability choice for trail, enduro, e‑MTB and riders who are hard on saddles.

Stainless

Durable and corrosion resistant. Good for wet, muddy or coastal riding.

Titanium

Premium lighter option with good ride feel. Sensible for performance riders, but not always the first pick for saddle smashers.

Carbon

Lightest option, but check clamp compatibility, rail dimensions and torque. Not the default choice for rough e‑MTB use.

Hollow rails

Not automatically weak. Strength depends on material, diameter, wall thickness, intended use and load rating.

Shell and padding

Shell flex, relief channel, padding density, rear ramp and edge protection all affect comfort and durability.
