From the very first meter, pure enthusiasm. First of all, after I had a herniated disc had to be a solution for my bike. The normal, suspension bridge with a good saddle left but 50 km away still in pain. With the rocker to the wheel now runs like on springs. The original spring in Holm was exchanged for a 100-120 kilo spring. The rocker abeitet freely without jerking and mosquitoes. An addition for those with back problems: DieSchwinge is now working with a Selle Royal saddle Premium Range Unisex 2012 City saddle. In the combination-unbeatable. For the extremely fast service 24 hours I am very grateful to the dealer!
