Question: Are the "Yakima RoundBars Rook Rack Cross Bars (58-Inches)" the correct bars to buy for the "Yakima 1A Raingutter System" towers?
Document: Any roof rack is going to make noise. The 58" crossbars have plenty of width to make enough noise that the driver could wear ear plugs if traveling many miles. You don't need to buy a Yakima "noise reducer". Go to the hardware store and get the 1" foam pipe insulation (that has a slit down it's length). The foam cuts easily. cover the middle and both ends of each cross bar.
After having installed the Yak rack system myself in 2006, now with 7 years of use and weathering in the 4 corners desert (Utah, Arizona, Colorado, New Mexico) as well as New England, I concur with all of the 5 star reviews. The vinyl on the round bars is in excellent shape, the tracks, landing base, locking control towers, Hull Raisers for the kayaks, and Raptor Aero bike racks have worked flawlessly on the cross bars.
used with QTowers (two different references, one for front and one for back), good match for my 2008 Prius. True the system is a pain to setup. But it feels well adjusted and reliable when in place. This 58 inches are a bit too long on an aesthetic point of view, but i don't really care as this roof rack does the work perfectly.
I had the Copperhead on my old Thule rack for years. To be fair, I think the new towers and carriers today are heavier than the old ones (whether you buy Thule or Yakima), plus my new Camry is a wider car than the Saturn SL2 or Toyota Corolla I had before. Both these things may contribute to added difficulties in gently and easily lifting the rack on and off the top of the car.
Before I bought my new rack I looked long and hard online at other posts on how it affects gas mileage, and these % seem pretty consistent with other people's cars.I used a Thule rack system to carry bikes on my cars from 1994 til 2007. After 14 years the Thule cross bars had lots of cracks in the plastic so you could see the steel underneath. When I bought a new car in 2007 I decided it was time to get a new bike rack.
The Yakima Round Bars for the Q Towers are heavily made and vinyl coated. They should support a lot of weight and last for many years to come! Very impressed with the sturdiness of these bars! Great buy!
These bars are great! They are exactly 58&#34; long and match up exactly with the holes in the towers. Additionally, the bike racks attach to the bars like they were made for each other. Met my expectations dead on.
Paired with Yakima towers, Hully Rollers and saddles these have given us a great kayak transport system. We are very pleased.
I should have been smarter and realized a round bar is not going to be very aerodynamic. These things whistle at any speed over 40 mph! Buy your vehicle's OEM cross bars. They will not whistle, will fit better, and probably will cost you less.To fix the situation I purchased Yakima's clip on wind fairing. Although it did dampen the noise, it's still loud enough to be annoying.
I presume that they are slightly more aerodynamically efficient than Thule's standard square bars, but can't prove it.The bars definitely increase wind noise when they are up there -- I'm even more inclined than usual to keep my speed down with the bars up there -- to keep down noise and minimize fuel efficiency decrease.Why did I buy Yakima's system instead of Thule's eight years ago? Well, I wanted to ensure that it would fit well on my vehicle.
Answer: yes
