Find the perfect saddle width for your sit bones. A properly sized saddle is crucial for comfort, preventing injuries, and maximizing cycling performance.
Saddle sizing is primarily determined by your sit bone width (ischial tuberosity distance). Unlike frame sizing, saddle width isn't related to your height – a tall rider might need a narrow saddle while a shorter rider might need a wide one.
The correct saddle width ensures your sit bones rest on the widest part of the saddle, distributing pressure properly and preventing soft tissue discomfort. Too narrow causes pressure on soft tissue; too wide causes inner thigh chafing.
| Sit Bone Width | Saddle Width | Riding Position | Common Profile |
|---|---|---|---|
| 90-100mm (Narrow) | 130-140mm | Aggressive/Racing | Common in men, racing cyclists |
| 100-115mm (Medium) | 143-155mm | Moderate/Sport | Most common width range |
| 115-130mm (Wide) | 155-168mm | Upright/Comfort | Common in women, casual riders |
| 130-145mm (Extra Wide) | 168-180mm | Very Upright | Comfort/cruiser bikes |
| 145mm+ (XXL) | 180mm+ | Cruiser/Recumbent | Specialty saddles |
Long, narrow saddles for aggressive positions.
Balanced comfort and performance for long rides.
Wide, cushioned saddles for upright positions.
Even the perfect saddle width won't be comfortable if positioned incorrectly. Saddle height should allow a slight knee bend at the bottom of the pedal stroke. Most saddles should be level or tilted slightly nose-down (1-3°).
Fore-aft position affects knee alignment and weight distribution. Your kneecap should be directly over the pedal spindle when the crank is at 3 o'clock. Improper positioning can cause knee pain or numbness regardless of saddle width.
