Riding posture is how you hold your upper body on the bike: how far your torso leans forward, how bent your elbows are, and where your hands and head sit. It matters because neck, low-back and hand pain are among the most common complaints in cyclists, and because a lower torso cuts drag but costs some power. Research on upper-body fit is thin, so treat the angle ranges here as fitters' starting points, not proven targets. From the side, the app reads your torso angle, arm-to-torso angle and elbow bend; it can't feel hand pressure or see your spine's curve.
Set the torso angle
Sit in your normal position with hands on the hoods and pedal easily. Your torso angle is the angle of the line from your hip to your shoulder, measured against the horizontal. Fitters use about 50–60° for casual riding, 40–50° for fitness riding and 30–45° for racing. These come from fitters' experience, not studies.
a forward lean you could hold for an hour without bracing.
Only go lower if you ride fast. In time-trial modelling, a flat-backed torso was never the best choice, and a more upright position came out ahead below about 30 km/h. Lowering the torso cost power and raised oxygen use. Lower is only faster when speed is high enough for drag to dominate.
low enough to be efficient, not so low you can't breathe or push.
Bend forward from the hips, not by rounding your upper back, and keep your torso still while your legs turn the pedals.
your hips do the folding; your chest stays open.
Soft arms, relaxed shoulders
Let your elbows bend a little. Don't lock them straight. Fitters suggest about 20–30° of elbow bend on the hoods, where 0° is a straight arm. In one study of 50 trained riders measured at rest on their own bikes, the average was about 19°, with a wide spread (3–45°).
elbows soft, so bumps go into your arms instead of your shoulders.
Keep your shoulders down and away from your ears, and your head up enough to see the road ahead. There is no researched target for the upper-arm-to-torso angle, so use comfort and a relaxed neck as the guide.
a long neck, shoulders easy, eyes up the road.
Light grip, change hand positions
Hold the bars only as firmly as you need to steer, and move your hands often between the tops, hoods and drops on longer rides. In a study of riders on a 600 km event, 23 of 25 had hand nerve symptoms afterwards. The authors recommended cycling gloves, a proper bike fit and changing hand position often.
hands resting on the bars, not hanging off them.
Feel it
Your torso is still and supported, your elbows are soft, your shoulders are low and you have a light grip you can shift around. Your neck isn't craning and your low back isn't aching. In a survey of more than 700 riders, neck pain was the most reported pain while riding (about 23%), then low back (22%) and hands (13%). Among professional road riders, 58% reported low back pain over one year. Riders who did core training had lower odds of pain, but that is an association, not proof. If pain or numbness keeps coming back, see a professional bike fitter or a clinician instead of forcing a position. The app reads your torso and arm angles from the side. It can't feel hand pressure or see how your spine curves.
Fix-its
- Your elbows are locked straight Soften them into a small bend, about 20–30° from straight as a starting point. If you can't bend them without stretching to reach the bars, the reach may be too long, so have the fit checked.
- Your neck or low back aches on longer rides Try a slightly more upright torso, and keep your shoulders low and your head up only as far as you need to see. Fitters often raise or shorten the bars here. Evidence linking specific bar positions to pain is limited, so change one thing at a time and see a fitter or clinician if it persists.
- Your hands go numb or tingle Change hand position every few minutes, wear padded cycling gloves and get your fit checked, as Patterson et al. recommend. Ease your grip and keep your elbows soft.
- You hold a deep aero tuck at low speed In time-trial modelling, a more upright torso came out ahead below about 30 km/h. Sit up on slow or easy sections and save the low position for fast ones.
- Your back rounds instead of your hips folding Rotate your pelvis forward on the saddle and lengthen your chest towards the bars. If you can't hinge that far, the bars are probably lower than your flexibility allows for now.
Drill
- Side-on check: on a trainer, film from the side at hip height for 1 minute of easy pedalling with hands on the hoods. Compare your torso angle to the range for your riding style, and your elbow bend to about 20–30°.
- Soft-elbow reps: on an easy ride, do 5 × 1 minute where you bend your elbows a little more and drop your shoulders, then 1 minute normal. Notice which feels steadier over bumps.
- Hand-position rotation: on rides over an hour, switch between tops, hoods and drops every 5–10 minutes.
- Drops tolerance: on a trainer or a quiet road, ride in the drops for 3 × 2–5 minutes with soft elbows. Build the time only while your neck and back stay comfortable.
