Car roof racks, what's the go to? Do the aluminium aero ones make a big difference? They seem jump up in price massively, happy to pay for quality, just don't know anything about them (or anything to do with cars in general).
Depends if you leave them on all the time, with mine on and two bikes on I do notice a difference in fuel consumption, but this is over 300-400 mile journeys. But it is not a great deal of difference.
