If you’re experiencing upper limb and neck pain, it’s likely due to too much pressure on your hands. When cycling on the flat at your functional threshold power (FTP)*or ~85% of your max heart rate, your hands should be almost weightless on the handlebars. If you are feeling heavy pressure through your hands at this intensity, it’s likely there’s a problem with your current bike fit.
*Functional Threshold Power is the maximum power you can put out over the course of 1 hr. This is measurable if you have a power meter on your bike. A non-power metric is sustaining 85% of your max heart rate.
Being unable to comfortably rest your hands on brake hoods, or opting for hand positions closer to the stem (where the handlebars connect onto the bike forks), are tell-tale signs a bike is too long. Having a reach too long for your body increases the weight distribution through the hands. By stretching forward for the bars, your centre of gravity is shifted into the front of the bike, meaning you will have to constantly brace your torso upward with locked elbows – essentially doing a plank while riding.
Excessive Reach is likely to result in elbow and shoulder injuries. To avoid these, consider the following adaptations:
The stem is the component on a bicycle that connects the handlebars to the steerer tube of the bicycle fork.
Insufficient stem height is one of the two most commonly rectified issues in a bike fit. Lowering your stem height to a more aggressive position may be more aerodynamic and might look more aesthetically pleasing but can often overexert recreational riders. Stems lowered beyond the rider’s tolerance results in weight being thrown forward onto their hands and increasing pressure through the arms. Plus, the added demands to neck extensor muscles, to hold your head up, often results in posterior neck pain.
Insufficient Stem Height is likely to result in neck and shoulder issues. Consider lifting the handlebars if you’re experiencing discomfort or pain after long rides.
Most off-the-shelf road bikes have handlebars too broad for riders, especially for women. Handlebars which are too wide can result in wrist discomfort as riders will often compensate by rolling the palms inwards to achieve a neutral shoulder position. A ball-park measurement for your handlebar width is the same distance between your acromioclavicular joints (ends of collar bone); this usually gives a neutral positioning to the wrists and shoulders. Larger frame sizes have even wider bars attached as standard, despite taller riders often being more slender in terms of shoulder width.
Excessive Handlebar Width can result in shoulder and wrist injuries. If you’re getting shoulder or wrist pain, consider measuring your shoulder span and look for alternate handlebars.
Brake levers should have a comfortable interface with the hand. Excessive downward or upward tilt imparts compressive forces to the wrist. Extreme cases can result in elbow and forearm pain. A very slightly up and inward tilted position is easily achieved by moving the hoods under your bar tape or changing the handlebar rotation.
Downward tilt to saddles is often incorrectly applied in a bid to relieve saddle pressure. As well as worsening the problem on those sensitive areas, it also leads to increased bracing forces on the upper body to prevent slippage down the saddle. Flatten your saddle and drop it ~15mm if your bum is uncomfortable – your arms will thank you for it.
Saddle fore/aft* is often wrongly adjusted as a means of shortening reach.
With insufficient saddle layback, your centre of gravity is thrown forward into the front of the bike, which increases pressure through arms and hands. This is common in riders who are trying to compensate for a bike that is too long for them, often resulting in elbow and hand pain. Consider sliding back the saddle rails and changing your stem length instead.
*Saddle Fore/Aft is how far forward the saddle is. On the underside of saddles, there are rails which can be allow the seat to slide forwards (fore) and backwards (aft).
Lowering saddle height is the other most rectified issue in a bike fit. Excessive saddle height results in the rider shifting their pelvis to one side as a compensation mechanism. This increases the pressure though your hands (usually your non-dominant side) in a bid to balance the bike. Consider lowering your seat and sitting squarer on the saddle if you’re getting one-sided hand pain, tingling or numbness.
These 7 aspects of bike setup and cycling posture should be analysed if you are experiencing persistent neck, shoulder, elbow or wrist pain when on the bike. If you are having trouble making these changes yourself, we have bike fitting services established at a number of our clinics.
There could be other contributing factors to your pain, such as inadequate recovery and previous injuries, so if in doubt or these changes do not help, contact one of our specialists for a comprehensive assessment of your symptoms and bike setup.
