Absolutely horny wheel !! Cultivation is really easy and the handling is just awesome. The extra Euros, a not quite unimportant gripe, are bearable! If you consider that the part of a few years, and even longer, will be in use, the additional price for the good processing is to cope. I can only say: It is worthwhile here to grab a little deeper into their pockets !! The adjustable rails, the fastening system can be understood without a plan. That's what a really good product stand out: It is self-explanatory !! The wheels, two full mountain bikes fit without any Wegschrauben and you do not even have studied in order to provide the wheels on the tracks on it ... My conclusion: Returns Technically not very cheap but a few euros more worthwhile and you will not regret it!
