Bike Cover for Roof Rack

I purchased a Sea Sucker roof rack for my car so I can transport my road bike. Does anyone use a cover for their roof mounted bikes? I am mostly concerned with bugs and am wondering if there is a good product that isn't too expensive. Skinz seems to have something in line with what I am considering (SKINZ PROTECTIVE GEAR) but also was thinking saran wrap could work too for far less money. I'm interested in folks' experience and opinions.

Why? Other than some mashed bug corpses embedded into the front of the bar wrap (that brushed off), none of my bikes have ever suffered from extended highway trips. Some even included driving torrential rain storms - which required a bit more remedial maintenance than a ride in similar conditions but not by much. Also such sails might add considerable adverse effect on mpg that the roof rack has already decimated.

If your not driving through a hailstorm you will be fine. I could only imagine my MPG with that skinz para sail on my roof.

I thought that it wasn't good to drive through rain at high speed with the bike exposed, that it could force water into the headset, bottom bracket, etc., much like a pressure washer.

Skinz looks like a nice product to prevent that.

There's really no reason to worry, but if you want to you might wrap some critical areas like the headset with something like this


stretch wrap that you can buy at Staples or most storage facilities.

As far as the headset goes, the thing to consider is where the gap between the moving parts is. Classic designs have the cups above, with a skirt extending below the cone so it naturally sheds water. However, in recent years designers started believing their own PR about sealed bearings, and some headsets now lack the skirt that served for years, and open to the side like this one, where the forward motion of the bicycle can drive water in. If your headset is of this design, you might want to use some wrap, or even a turn of electrical tape if driving through rain.

There used to be a product called a "B-String" I don't remember who made it. Yakima or Thule maybe. It was a stretchy fabric thing that covered the front of a bike being carried on a fork mount roof rack. It definitely cut way, way down on road grime and the number of bug strikes.

Driving through the Everglades of South Florida is like driving in the rain...except it's bugs.

The thing to keep in mind, whatever you decide, is windage. At highway speeds the wild load on the bikes is significant. Adding "sails" will greatly increase the wind load on the bikes, and rack. With only one bike, it may not be an issue, but with multiple bikes it can be significant and not only cost you in fuel, but possibly cause a failure whereby bikes are blown off the roof.

So, if you decide to protect the bike, do so wisely, without adding to the sail area.
