Hello. I have a 2017 Trek Silque S7 women's bike and need to purchase a bike rack. My car is a 2016 Volvo XC60. I would love your recommendations - it'd be great not to spend a ton of money. I don't yet have a hitch and I have read in some places that carbon bikes should be placed in frames vs. hitched to one. Could you please advise? I would probably get a rack for two.
