It\'s been some time since I ordered three WHEELDOCK SPORTDOCK3 stands. The gentleman I ordered from asked for feedback on how they worked for me in my trailer. He was also kind enough to give me Quick-Detach Transportation Bars for all three. All I can say is Thank You, Thank You, Thank You! Tried my fair share of the less expensive ones, and actually had on bike tip because of the front wheel wobble effect that can result from a cheap chock. After that, I contacted WHEELDOCK, had the three sent to me, and now my bikes travel completely secure. The nicest feature, in my opinion, is you can fasten your front wheel to the WHEELDOCK itself. The front wheel is wobble free anyway, thanks to the gas cylinder and tight tolerances on the stand. I can worry about the drivers on the road in front of me (and behind of course!) and not about bikes in my trailer behind me. Once installed, WHEELDOCKS, with the Quick-Detach Transport Ba r, make loading and unloading a quick, simple, easy process. I can virtually remove anything to trip me up, or run over with any of my bikes. Then I can focus on the real fun, riding! Sorry, I wish I can remember who I spoke with personally, a super nice guy, and true business professional. If you can find out who he was, please tell him Thank You. If you should use this testimonial for advertising, those looking at the cheap chocks, you pay for what you get! Especially with sport bikes, a few dollars saved on cheap chocks can cost you later in body parts, and the effects of compressed forks.(Another nice feature I almost forgot!) WHEELDOCKS allow you to travel with peace of mind, and allows to fun to begin on arrival, WHEELDOCKS are worth every penny, and then some.
