German cyclist is very amazed with how good the feeling of smoothness and buttery feeling after using Deuthlon AquaSpeed grease. He called this a 'miracle juice'. It given him SUPER performance.
He also mentioned that all his bikes are highly optimized. Never in his mind thought of any product is able to give him a much much BIG performance enhancement difference. Well, Deuthlon does it for him.
Thank you Nick Freyer.
