The fluctuating heat alone can damage the rubber and plastic parts even if there is absolutely no UV exposure
I have stuff in the attic where it gets really hot in the noon so the temperature fluctuates quite a bit. The plastic and rubber things became brittle after a time.
If using shed to store bike, make sure it doesn't get hot inside. Temperature must be kept at room temperature as much as possible. Heat is worse than humidity. Ofc, direct exposure to rain is still worse
