WHO THIS IS FOR
IS THIS YOU?
The rider with nagging knee pain
You experience dull aching in one or both knees during or after rides and it is not improving.
The new cyclist with front-of-knee pain
You have recently started riding and your kneecaps ache after every session.
The rider who changed equipment
Knee pain appeared after changing saddle, pedals, shoes, or bike and you suspect a fit issue.
THE ROADMAN VIEW
The Roadman view
Knee pain is the most common overuse injury in cycling, and it is almost always fixable. The knee is a hinge joint caught between the hip and the ankle — it does what they tell it to do. When something in the chain is misaligned, the knee absorbs the error thousands of times per hour.
Start with the diagnostic: where exactly does it hurt? Front of the knee almost always means the saddle is too low, pushing the patella into the femur under load. Outside of the knee points to cleat rotation forcing your foot into an unnatural angle. Inside of the knee suggests your cleats or pedals are pushing your stance too wide or too narrow.
The good news is that Dr Andy Pruitt has documented over 30,000 bike fits, and his data is unambiguous: the vast majority of cycling knee pain resolves with millimetre-scale adjustments to saddle height, cleat position, and training load. You do not need surgery. You need a competent bike fitter and two weeks at reduced volume.
EXPERT EVIDENCE
WHAT THE EXPERTS SAY
- Dr Andy PruittFounder, Boulder Centre for Sports Medicine
Anterior knee pain in cyclists is most commonly caused by a saddle height that is 2-3 cm too low, placing excessive compressive load on the patellofemoral joint. Correction to the proper saddle height — measured as 25-35 degrees of knee flexion at the bottom of the pedal stroke — resolves symptoms in 80% of cases within three weeks.
- Professor Phil BurtFormer head of physiotherapy, British Cycling
Cleat position is the most underappreciated variable in cycling knee pain. A cleat rotation error of just 2 degrees creates a torsional force that compounds over 5,000 pedal revolutions per hour. Self-adjusting float in the pedal system mitigates this, but many riders clamp their cleats down with zero float.
PRACTICAL APPLICATION
DO THIS WEEK
Map the pain location
Front of knee: raise saddle 3-5 mm and check crank length is not excessive for your leg length. Outside: check cleat rotation and add 1-2 degrees of float. Inside: check Q-factor and cleat lateral position. Keep a pain diary for two weeks after each change.
Reduce training load by 30% for three weeks
Drop your weekly volume by roughly a third while you implement fit changes. Continue riding but avoid high-torque efforts — no standing climbs, no big gear work. Spin at 85-95 rpm in moderate gears.
Get a professional bike fit
A qualified fitter with motion-capture or video analysis can identify alignment issues that are invisible without measurement. Budget for a comprehensive fit — it is cheaper than physiotherapy and more effective than guessing.
Strengthen the stabilisers
Single-leg exercises — step-ups, single-leg press, Bulgarian split lunges — build the hip and knee stabilisers that control tracking under pedalling load. Two sessions per week for six weeks resolves most residual instability.
COMMON MISTAKES
WHAT CYCLISTS GET WRONG
MISTAKERiding through knee pain without changing anything.
FIXKnee pain during cycling is a signal that something in the system is wrong. Continuing without investigation turns a fixable fit issue into a chronic overuse injury.
MISTAKERaising or lowering the saddle by large amounts at once.
FIXMake saddle height changes in 3-5 mm increments and ride for a week between adjustments. Large changes create new compensations.
MISTAKEIgnoring cleat alignment.
FIXCheck cleat position every time you change shoes or cleats. Mark the position with a paint pen before removing cleats so you can replicate it precisely.
