I recently bought my first Specialized bike - a Sirrus X 4.0 gravel bike. I've had it about 3 weeks and have been riding it 4-5 days a week, about 6-12 miles per ride. Yesterday while riding, I felt the left pedal go loose and then immediately fall off - luckily I wasn't going too fast and was able to stay upright. Wondering if this is likely due to loosening during the initial break-in period or if it may not have been assembled correctly? Is this something I'm going to have to check and tighten regularly?


Also wondering if anyone has tips on how I can best learn about maintaining this bike? There's no "user manual" and everything on it requires tools. I'm not a total novice, but it's also more complicated that the Treks I've owned.


One other note: the bike shop where I bought this is currently closed because an employee tested positive for Covid last week, so I'm on my own for a bit with this. Trying to borrow a torque wrench so I can put the pedal back on!
