Sorry if this seems super dumb but I noticed my bike had a flat on Sunday night. I took it to the bike shop and got some air for it but in the 10 minutes it took me to ride back home it was flat again. I just went downstairs to check the wheel – there’s nothing puncturing it so I’m wondering if anyone can help me troubleshoot the problem.
Thank you so much in advance
