Using only one strap to hold the bike on wasn't a good idea. When it broke, the security cable kept the bike from being lost, but the handelbar and brake lever were customized.
My seat adjustment screws had worn through an oury grip previously, so I shifted the bike away but could only hold it with one wheel strapped instead of two. Bad decision. Actually, being dragged and only damaging the handelbar, grip, and brake lever were about the least damage I could hope for.
This is the second bike carrier mistake I've made. Previously on a different rack, I mounted the front end improperly on a hanging rack, front dropped down and I taco'd the wheel.
- mount the bike as recommended
- use security cable for theft prevention and backup retainer
- use cardboard, plastic cup lid, etc. to separate bike contact points.
