Hi @KentFam I have successfully used the saris carrier for two trips so far;
1, with admittedly two very light adult gravel bikes from Leeds to Skipton with no issues.
2, then fully loaded with three children’s bikes from Leeds to Filey.
it’s super light and rock steady once tightened up and is fully adjustable, I have not seen any issues with the spoiler either.
cheers,
Peter
