WHAT CAUSES SADDLE SORES IN CYCLING?

By Anthony WalshRoadman CyclingUpdated 10 July 2026

ANSWER

Saddle sores are localised skin lesions — ranging from chafing and folliculitis to deeper abscesses — caused by the combination of friction, moisture, pressure, and bacterial colonisation at the contact point between skin and chamois. Research by Leibovici et al. found that 58% of competitive cyclists report saddle sore episodes, with ride duration, humidity, and chamois hygiene as the strongest predictors. Prevention requires a correctly fitted saddle, quality bib shorts with an antibacterial chamois, chamois cream applied to both skin and pad, and immediate post-ride showering. Chronic or recurrent sores that do not resolve within seven to ten days warrant medical review.

KEY TAKEAWAYS

Saddle sores result from friction, moisture, pressure, and bacterial colonisation at the skin-chamois interface.
58% of competitive cyclists report at least one episode — they are common but preventable.
Chamois cream, antibacterial chamois pads, and immediate post-ride hygiene are the three most effective preventive measures.
Sores lasting beyond seven to ten days or recurring frequently should be assessed by a doctor.

WHO THIS IS FOR

IS THIS YOU?

The rider with recurring sores

You develop saddle sores every few weeks despite riding regularly and want to break the cycle.

The new cyclist with skin irritation

You have started riding and are experiencing chafing, redness, or painful bumps in the saddle contact area.

The long-distance rider

You ride multi-day events or back-to-back long days and need strategies to prevent sores over consecutive riding days.

THE ROADMAN VIEW

Saddle sores are the problem nobody wants to talk about but everybody experiences at some point. They range from mild chafing — a red patch that stings in the shower — to full-blown abscesses that can take you off the bike for weeks. The cause is always the same triangle: friction, moisture, and bacteria.

Friction comes from the chamois moving against skin. A chamois that is too thin, has rough seams, or does not match your anatomy creates hot spots. Moisture — from sweat or rain — softens the skin and makes it more vulnerable to damage. Bacteria colonise the damaged skin, turning a minor abrasion into an infected follicle or abscess.

The fix is a three-layer defence. First, chamois cream — applied generously to both skin and pad — reduces friction and provides an antibacterial barrier. Second, quality bib shorts with a multi-density, seamless chamois that wicks moisture away from the skin. Third, never sit in wet shorts after a ride. Get out of them and shower within 30 minutes of finishing. That alone prevents the bacterial colonisation that turns chafing into infection.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Dr Victor LeiboviciDermatologist and sports skin researcher
A study of competitive cyclists found that 58% reported saddle sore episodes over a 12-month period. The strongest predictors were ride duration exceeding two hours, high ambient humidity, and delayed post-ride hygiene. Folliculitis (infected hair follicles) was the most common presentation, followed by furuncles (deeper abscesses) in riders who continued training through early-stage sores.
Dr Andy PruittFormer director of the Boulder Centre for Sports Medicine, bike fit pioneer
Saddle sore prevention begins with saddle fit. A saddle that is too narrow forces weight onto soft tissue, creating excessive pressure and friction. A saddle that is too wide causes inner-thigh chafing against the saddle edges. Correct saddle width, combined with proper chamois selection and hygiene practices, prevents the majority of saddle sore presentations.

PRACTICAL APPLICATION

DO THIS WEEK

Apply chamois cream before every ride over 60 minutes
Apply a generous layer of chamois cream to both the skin contact areas and the chamois pad itself. Reapply on rides over four hours. The cream reduces friction and provides an antibacterial barrier that prevents bacterial colonisation of micro-abrasions.
Shower and change within 30 minutes of finishing
The warm, moist environment inside worn cycling shorts is an ideal breeding ground for bacteria. Remove shorts immediately after riding and wash the contact areas with mild soap and water. This single habit prevents more saddle sores than any other intervention.
Never re-wear dirty cycling shorts
Wash shorts after every ride. Bacteria accumulate in the chamois pad during use and multiply during storage. Wearing yesterday's shorts today introduces a concentrated bacterial load directly onto skin that may already have micro-abrasions from the previous ride.
Check saddle width and tilt
A saddle that is too narrow drives weight onto soft tissue; too wide causes thigh chafing. Tilt should be level or one degree nose-down. Even two degrees nose-up increases perineal pressure and friction, which accelerates sore formation.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

MISTAKEWearing underwear beneath cycling shorts.
FIXUnderwear seams create friction points directly on the skin. Cycling shorts are designed to be worn without underwear — the chamois sits directly against skin to minimise seam friction.
MISTAKERiding through an infected saddle sore.
FIXContinuing to ride on an infected sore drives bacteria deeper into the tissue and can turn a minor folliculitis into an abscess requiring surgical drainage. Rest until the infection resolves. If the sore is painful, swollen, or warm to the touch, see a doctor.
MISTAKEUsing thick padding to compensate for a poorly fitted saddle.
FIXExtra padding compresses and shifts during riding, creating more friction, not less. A properly fitted saddle with a thinner, multi-density chamois outperforms a poorly fitted saddle with maximum padding.

FAQ

FREQUENTLY ASKED QUESTIONS

What do saddle sores look like?

Early-stage saddle sores present as red, raised bumps similar to spots — often around hair follicles. They may contain a white head (folliculitis) or appear as a deeper, painful lump without a head (furuncle). Chafing presents as raw, red skin without a raised bump.

How long do saddle sores take to heal?

Minor chafing resolves in two to three days with rest and hygiene. Folliculitis typically clears in five to seven days. Deeper abscesses may take two to four weeks and sometimes require medical drainage. Do not ride until the sore is no longer painful to pressure.

Should I pop a saddle sore?

No. Squeezing or lancing a saddle sore risks driving bacteria deeper into the tissue and spreading infection. Apply a warm compress for 10-15 minutes several times daily to encourage natural drainage. If the sore does not resolve within seven to ten days, see a doctor.

Does shaving cause saddle sores?

Shaving can increase saddle sore risk by creating micro-cuts and ingrown hairs in the contact area. If you prefer hair removal, trimming with clippers rather than shaving reduces ingrown hair risk. If you do shave, allow 48 hours before riding to let the skin recover.

What chamois cream should I use?

Any reputable cycling-specific chamois cream with antibacterial properties works. Avoid products with menthol or strong fragrance on broken skin. Assos, Rapha, and Muc-Off all produce effective options. The amount applied matters more than the brand — use enough to create a visible layer on both skin and pad.

Can saddle sores become serious?

Rarely. Most saddle sores are superficial skin infections that resolve with rest and hygiene. However, deep abscesses that do not drain naturally may require antibiotics or surgical drainage. Riders with diabetes or compromised immune systems are at higher risk of complications and should seek medical advice earlier.
