A couple of years ago I purchased a Trek Bicycle from Ken Denney in Maineville. He advertises himself as "The Bike Guy." I returned to his shop, which is actually his house, to have new tires put on the bike and for adjustment. I specifically told him that I did not want Chinese tires to replace the Continental German handmade tires that I had. He assured me that I would get "Continental" tires. The tires he put on the bike are Chinese tires and I consider them inferior and unsafe. The bike had Mavic French made wheels when I purchased it and when I took it to Ken Denney for maintenance. After getting the bike back I noticed that the front wheel had been replaced with a cheap wheel and the $170 Mavic wheel was not there. He tried to say that the wheel had not been replaced, but clearly the back wheel is a Mavic wheel. It appears as though he may have wanted to sell my Mavic to another customer. He became very irate when I questioned him and hung up on me. If you take your bike to this guy, which I do not recommend, make sure he does not perform a switch on you. I now must replace the tires and the front wheel. Beware. read more
