Hip Pain From Cycling: Bike Fit, Bursitis and the Hip Flexor

How does bike fit affect the hip, and what changes help?

Your hip bends the most at the top of the pedal stroke. A clinical commentary on bike fit for cyclists with hip pain explains that this repeated peak flexion can provoke pain in people with hip joint problems and may cause repetitive impingement in hips shaped for femoroacetabular impingement (FAI).

Several fit factors change how deeply your hip bends. A saddle set too low, too far back, a long reach to low handlebars and cranks that are too long for your legs all increase hip flexion at the top of the stroke.

The same commentary notes that a saddle set too far back also loads the hamstring and gluteal muscles more, which can lead to pain at the back of the hip or worsen pain inside the joint.

A professional bike fit is worth considering if you ride often and have hip pain. These are common starting points to discuss with a fitter or physical therapist.

A fitter can also check whether your position allows the hip to stay comfortably short of its end range at the top of the stroke, which the commentary recommends for riders with hip pain.

• Saddle height: high enough that the knee stays slightly bent at the bottom of the stroke
• Saddle setback: not set so far back that the hip has to fold deeply
• Handlebars: a higher or closer position reduces how far you lean forward
• Crank length: shorter cranks can help riders with shorter legs or stiff hips
• Leg length difference: shims under the cleat can even out the two sides
• Cleats: positioned so the knee tracks comfortably over the foot

Why does the front of my hip hurt on the bike?

Pain in the front of the hip or groin is often hip flexor overload. The hip flexors work with every upstroke, and long climbs, standing efforts and pulling up hard on clipless pedals add strain.

If the pain is deeper in the crease, comes with a pinch when you are low on the drops, or lingers off the bike, the joint itself may be involved. FAI and labral tears often flare in the most aggressive, folded riding positions.

Raising the handlebars, spending more time on the hoods and shortening very long rides are reasonable first steps while the hip settles.

What about outer hip and sit-bone pain?

AAOS OrthoInfo lists bicycling among the repetitive activities that can contribute to hip bursitis, along with a tight IT band. This pain sits over the bony point on the outside of the hip and is often worse lying on that side at night.

Interestingly, the bike fit commentary notes that tendon problems and bursitis are relatively less common in cyclists than muscle pain around the hip. That makes muscle overload and fit issues the first things to look at.

Pain at the sit bones, deep in the buttock, can come from saddle pressure or irritation of the hamstring tendons where they attach to the pelvis. A saddle set too far back increases the load on the hamstrings and gluteal muscles with every stroke. Persistent pain here, especially pain with sitting, deserves an exam.

Could one-sided cycling hip pain really be my back?

Yes. Cycling holds the lower back in a flexed position for long periods, and back problems can send pain into the buttock, hip and thigh. MedlinePlus notes that pain felt in the hip may reflect a problem in the back rather than in the hip itself.

Clues that point to the back include pain that travels below the knee, numbness or tingling, and pain that changes with how you hold your spine. Pain from the hip joint itself is often felt most in the groin.

Our team checks the lower back at every hip exam for exactly this reason. Treating the wrong area wastes time and miles.

Is cycling good for arthritic or replaced hips?

For many people, yes. AAOS OrthoInfo recommends switching from high-impact activities like jogging to lower-impact options such as swimming or cycling when hip arthritis is present, because they put less stress on the joint.

After a hip replacement, OrthoInfo lists bicycling among the preferred lower-impact activities, and a stationary bike is often part of early rehabilitation. Your surgeon will tell you when it is safe to ride outdoors, where balance and falls are a bigger concern.

For stiff, arthritic hips, a step-through frame, a higher handlebar and a slightly higher saddle can make getting on and pedaling more comfortable.

What can I do off the bike?

Cyclists often have strong quadriceps but relatively weak glutes and core, because pedaling works mostly in one plane. Adding bridges, side planks, side-lying leg lifts and step-ups two or three times a week helps the hip stay stable on the bike.

Gentle hip flexor and quadriceps stretches after rides can ease tightness, as long as they do not pinch the front of the hip. Easing back on mileage, intensity or climbing for a week or two lets irritated tissue settle.

When you build back up, change one thing at a time, such as ride length or saddle position, so you can tell what helps.

When should a cyclist see a hip specialist?

See a specialist if hip pain persists after fit changes, keeps returning on longer rides, causes a limp off the bike, or comes with clicking, catching, numbness or night pain.

Bring photos of your riding position or your bike fit report if you have one. Our Saturday Hip Pain Clinic is a convenient time for active adults to get an exam and a plan.
