Cycling InjuriesBack, Knee & Neck Pain for Cyclists
Lower back pain, knee pain, neck and upper trapezius tension, and hand numbness on the bike. Position and musculoskeletal restrictions both contribute.
Book Your First VisitCycling places the body in a sustained position while the legs repeat the same movement pattern thousands of times. Most cycling injuries arise from the interaction between the rider's body and the bike position. In my experience, treating the body and the position together tends to produce better results than either alone. A bike fitter optimises the bike; a chiropractor addresses the musculoskeletal restrictions that determine what positions are achievable. If a fit helped initially but symptoms have returned, the body is often where the remaining work is.
Why cycling position is central to most cycling injuries
Cycling places the body in a sustained, relatively static position for extended periods while the legs repeat the same movement pattern thousands of times per ride. Unlike running, there's no impact loading; instead there's sustained spinal flexion, hip flexor loading in a shortened position, repetitive knee joint movement, and prolonged neck extension to maintain forward vision. Cyclists show measurable changes in lumbar lordosis compared with non-cyclist athletes. Most cycling injuries arise from the interaction between the rider's body and the bike position.
Bike fit and clinical treatment work together. I can assess and treat the musculoskeletal restrictions and imbalances (tight hip flexors, restricted thoracic extension, limited hip internal rotation) that affect how you sit on the bike and how load is distributed. A qualified bike fitter can then optimise your position around your improved physical capacity. Addressing only one without the other often produces incomplete results.
Common presentations
- Lower back pain: extremely common in cyclists, typically from sustained lumbar flexion combined with tight hip flexors that limit posterior pelvic tilt and increase lumbar flexion load. A saddle too low exacerbates hip flexor shortening; saddle too far back increases lumbar flexion. Often improved by addressing hip flexor length and thoracic extension alongside saddle height adjustments.
- Anterior and medial knee pain: primarily driven by saddle height. A saddle too low increases patellofemoral compression and medial knee loading. Cleat alignment and foot position also affect knee tracking and can drive both medial and lateral knee pain. Saddle height is one of the most important variables for cycling knee pain.
- Neck and upper trapezius tension: from sustained cervical extension on an aggressive or low position. Builds progressively during long rides. Handlebar height and reach length are the primary position variables; tight hip flexors and restricted thoracic extension forcing compensation through the cervical spine are the main physical contributors.
- Hand and wrist numbness: typically ulnar nerve compression (ring and little fingers) or median nerve compression (thumb, index, middle fingers), depending on hand position on the bars. Primary cause is usually too much body weight on the hands from a reach that is too long or bars that are too low. Cervical nerve involvement can produce the same symptoms and will be screened for clinically.
What helps
Manual therapy can address hip flexor restriction, improve thoracic extension, and restore lumbar and cervical range of motion, reducing how aggressively the position loads these structures. This work is most effective when combined with position adjustments that address the ongoing mechanical cause. If the position is genuinely inappropriate for your body, manual therapy alone addresses the symptoms without removing the source. Some position adjustment is usually part of the full solution.
Most cyclists can continue riding during treatment, often with some temporary adjustment to volume or intensity. If you have an event in mind, starting earlier in your build tends to produce better results. I'm happy to communicate with a bike fitter about what's been addressed and what physical capacity has changed.
If you've had a professional bike fit and symptoms initially improved but have since returned, this often signals that physical restrictions have reset, or that the original fit was working around limitations that haven't been fully resolved. In my experience, addressing those underlying restrictions first tends to produce more lasting results than returning for a second fit alone.
On saddle height and knee pain
Saddle height is one of the most important variables for knee pain in cycling, and a saddle significantly too low is a common finding. But it's not always the whole answer. Cleat alignment, foot position, saddle fore-aft, and hip abductor strength all contribute to knee mechanics on the bike. I'll assess knee pain clinically and give you my view on what's driving it alongside any position recommendations. Small saddle height changes sometimes produce meaningful improvements in knee symptoms.
Cycling injuries are often load and position problems as much as tissue problems, and getting the right clinical picture often means looking at both together. If you'd like to talk through your situation before booking, get in touch.
When to seek care promptly
See a doctor if you have:
- Acute knee swelling after a crash or a sudden loading incident
- Hand or arm weakness alongside numbness during rides
- Back pain with leg symptoms: numbness, weakness, or sciatica pattern
- Pain that is worsening with training volume despite position adjustments
- Groin or hip pain with any catching or clicking in the hip joint
- Numbness or tingling in the perineum or saddle contact area during or after rides
Most cycling overuse injuries are appropriate for conservative management. Structural injury and progressive nerve symptoms need assessment before continuing training at the same load.

Common questions
Ideally both, in either order. They address different things. A bike fitter optimises the bike to the rider. A chiropractor addresses the musculoskeletal restrictions that limit what positions are achievable and tolerable. If you have significant hip flexor tightness or restricted thoracic extension, a bike fit around those restrictions may not hold if treatment changes your physical capacity. In my experience, most cyclists get better lasting results from treating the body first and then refining the fit.
Saddle height is one of the most important variables for knee pain in cycling, and a saddle that is significantly too low is a common finding. But it's not always the whole answer. Cleat alignment, foot position, saddle fore-aft, and hip abductor strength all contribute to knee mechanics on the bike. I'll assess your knee pain clinically and give you my view on what's driving it before advising on bike position changes.
Handlebar numbness in cycling is usually from ulnar nerve compression (ring and little fingers) or median nerve compression (thumb, index, middle fingers), depending on how your hand sits on the bars. Primary causes: too much body weight on the hands from a reach that's too long or bars that are too low, wrist extension for extended periods, or vibration on rough roads. Padded bar tape and gloves help, but addressing reach and handlebar height is more likely to address the underlying cause. Cervical nerve compression can also contribute; I'll screen for that.
Usually yes. Most cyclists continue riding during treatment, often with some temporary adjustment to volume or intensity. Pushing through high-load rides during a flare-up can slow progress, but staying completely off the bike is rarely necessary. If there are specific rides or events that may complicate recovery, I'll tell you clearly and help you think through the options.
Acute low back pain typically settles within a few weeks; cycling-related acute back pain generally follows the same pattern, particularly with temporary load reduction. Chronic cycling back pain that has been building over months typically takes several weeks to a few months to improve significantly, with the best results coming from combining treatment with position changes and hip mobility work, though some residual discomfort is common in longstanding cases before position factors are fully addressed. Pain that is exclusively present during or after riding (absent when not cycling) often responds well once the relevant position variables are identified. If you have an event or target ride in mind, it's worth starting early, since in my experience, improvement in ride comfort often begins within the first few treatment sessions, before a full course is complete.
