I’m storing my bikes in a metal bike shed. The thermometer I have in there shows that the temperature has gone as high as 52°C, should I be worried?

All the bikes in there have hydraulic disk brakes. Mixture of tubeless and inner tubes, but relatively wide tyres (32c is the thinnest) tyre pressures usually around the middle of the range marked on the sidewall. One of the bikes is electric, but I charge the battery indoors.

Tires will age faster though probably not significantly so if you ride frequently (meaning that by the time they really degrade you’ll be changing them out anyway). I took my bike to India when I worked there and kept it in a shed where temperatures soared to 67 centigrade in summer (outside was 51). High temps there last from about March to October. Bike was fine.

But it will significantly degrade the sealant in tubeless tires so you’ll have to replenish more, a lot more.

Not a big problem for a bike but watch out for other things in your shed/garage, I found this during the last heatwave

It won’t damage your bike but it will reduce it’s life. Tyres will lose their flexibility sooner and components will degrade a little faster than they would at normal room temperature.

I recommend resetting that thermometer and relocating it away from the exterior metal wall of the shed. It may not be getting quite that hot.

might be worth keeping a close eye on your tires & tubes, exposure to extreme heat can accelerate rubber degradation

In operation hydraulic brakes run between 50° and 150°C and can go as high as 300°C without suffering damage, so a 50° shed shouldn’t do them any harm. As far as tyres go, for a 60 psi tyre, pressure will rise roughly 1 psi per 5° extra heating, so if you pumped them up to 60 psi on a balmy 20° day, if the temperature rises to 50° in your shed they are only going to gain an extra 6 psi. Even with very high pressure tyres, at 100 psi pressure increases one psi per 3° heat rise, so even then you’re only going from 100 psi to 110 psi with a 20° to 50° increase, not enough to blow it.

should I be worried

Yes – the world is burning!
