Saddle Sores and Sit-Bone Pain: Causes and Fixes
Pain where you sit is the most common reason people give up on cycling, and it is almost never about needing a softer saddle. In most cases the saddle is at the wrong height or angle, or is the wrong width for your sit bones. This guide explains what causes the pain and which adjustments actually solve it.
Saddle pain is almost never solved by a softer saddle. Your weight should rest on the sit bones, so the three real causes are saddle height (hips rocking), saddle tilt, and a saddle narrower than your sit-bone spacing.

Why it hurts where you sit
Your weight on a bike should rest on your sit bones, the two hard points at the bottom of your pelvis, built to carry load. When it rests anywhere else, on the soft tissue in front of them, you get burning, numbness and saddle sores. Almost every case of saddle pain comes down to weight sitting in the wrong place.
That is why a softer, wider saddle usually makes things worse rather than better. Thick padding lets your sit bones sink in, so the soft tissue around them takes the pressure instead. Comfort saddles feel fine in the shop and hurt after an hour.
The three real causes
1. Saddle height
If the saddle is too high, your hips rock side to side to reach the bottom of each pedal stroke. That rocking rubs your skin against the saddle with every revolution, the classic cause of saddle sores on both sides. If the saddle is too low, you sit further forward on the nose, where there is no support for your sit bones.
- How you notice: sores or chafing on both sides, and hips visibly rocking when someone films you from behind.
- Fix: adjust height in small steps of a few millimetres and re-check after a ride.
2. Saddle tilt
A saddle tipped nose-down slides you forward, so you brace with your arms and push your soft tissue into the saddle nose. A saddle tipped nose-up presses directly into the perineum.
- How you notice: nose-down gives sore hands and pressure at the front; nose-up gives numbness in the middle.
- Fix: start level. Put a straight edge along the saddle and adjust to horizontal, then fine-tune by one or two degrees at most.
3. Saddle width
Sit bones vary a lot between people. A saddle narrower than your sit-bone spacing leaves them unsupported and everything else takes the load.
- How you notice: pain low down and central rather than to the sides, on an otherwise well-adjusted bike.
- Fix: measure your sit-bone width (many shops do this free) and pick a saddle that matches it. Width matters far more than padding.

Measure my saddle position →What about shorts and creams
Good bib shorts with a quality pad, worn without underwear, and chamois cream on longer rides genuinely help, but they manage symptoms. If your position is wrong, the best shorts in the world only delay the pain. Fix the position first, then let the kit do the rest.
Sores that are already there
Existing saddle sores need time off the bike to heal. Riding through them raises the risk that a small irritation turns into an infected sore that costs you weeks. Keep the area clean and dry, change out of cycling shorts straight after riding, and if a sore becomes hard, hot or filled with pus, see a doctor.
Finding your own numbers
Saddle height, tilt and setback are exactly what a bike fit measures. A BikeFit/LAB analysis films you pedalling and reports your actual saddle height and fore/aft position against the range that suits your body and riding style, so instead of guessing which of the three causes is yours, you get the measurement and the millimetres to change.
FAQ
Why does my bike saddle hurt so much?
Usually because your weight is not resting on your sit bones. A saddle that is too high, tipped nose-down, or too narrow for your sit-bone spacing puts pressure on soft tissue instead, which causes burning and saddle sores.
Does a softer saddle help with saddle pain?
Usually not. Thick padding lets your sit bones sink in so the soft tissue around them carries the load. A firmer saddle of the correct width for your sit bones is normally more comfortable over distance.
How do I stop getting saddle sores?
Set the saddle at the right height so your hips do not rock, level the saddle, choose a width that matches your sit bones, and wear good bib shorts without underwear. Let existing sores heal before riding hard again.
