Numb hands and tingling on the bike
Your hands go numb on the bike when the weight of your torso rests on the bars and compresses the ulnar or the median nerve in the palm. If the ring and little finger go, it is the ulnar nerve; if it is the thumb, index and middle finger, it is the median. The cause is always the same underneath: too much load on the hands for too long. The fix is to give that weight back to the saddle and the legs, not to buy thicker gloves.

Which fingers go numb tells you where the compression is
This is one of the few cycling symptoms you can place accurately yourself. If the tingling runs through the ring and little finger, you are compressing the ulnar nerve against Guyon’s canal, at the base of the palm. If it is the thumb, index and middle finger, it is the median nerve in the carpal tunnel.
In both cases the cause is the same: too much weight on the hands for too long, on a wrist that is badly angled while it carries it.
It usually arrives in stages: first pins and needles you shake out at a junction, then numbness that stays for the rest of the ride, then a hand you would rather not trust on a technical descent. The early stage is by far the easier one to fix.
Why changing gloves almost never works
A gel glove spreads the pressure a little. But if your torso is dumping fifteen kilos onto your hands, no amount of padding will fix that. It is treating the symptom.
The real work is returning that weight to the saddle and the legs: moving the saddle back, correcting its angle, raising or shortening the front end, and placing the levers so the wrist lines up with the forearm instead of bending back against it.
Bar rotation and lever height change wrist position completely when you ride on the hoods or in the drops. It is a two-minute adjustment that resolves a good number of cases, and one of the first things we try. We also look at bar width: if the bars are wider than your shoulders, the arms splay, the wrist rotates and the ulnar nerve pays for it.
How much weight your hands carry is not a fixed number. It shifts with saddle angle, with the pelvis rolling forward as you tire, and with the terrain under you. So the aim is not a tidy figure on the stand. It is a position with enough margin left to survive the last hour of a long ride.
When to see a healthcare professional
If the tingling lasts for hours after you get off the bike, if it turns up at night or while driving, or if you notice grip strength dropping away, get it looked at before booking a fit. There may be a nerve compression that has nothing to do with cycling.
Numbness is worth taking seriously on its own terms. Of all the complaints on this list, it is the one we would rather see checked early than managed for a season.
