Two weeks ago I bought Trek Checkpoint ALR5. Bike rides pretty well. It has aluminium frame. I bought it primarily for bike packing trips as it has ton of mounting points.
After riding it for 2 weeks and hitting some easy gravel roads I found two relatively small dents on bicycle's frame. They are probably caused by flying rocks from the wheels. In total I rode around 100 km on gravel trails and the riding wasn't too extreme. Those dents made me a little bit paranoid about the bike's frame strength, and made me wonder how the frame will look like after one year.
Are these dents normal or do they show that bicycle has a fragile frame? Can they cause problems? Do they compromise the bike's structural strength?
