Matches the vehicle. Tal vez para una bicicleta de ruta donde se reduce el contacto entre llanta y rodillo el ruido sea menor. Battery life- so far so good. Bumps on the soles make them uncomfortable. It came with elastic to put the beads on. Best shoe rack ever purchased. I guess the vendor imports them from somewhere. I didn?t like that it said it was new on the add and when it arrived it was a refurbished item with no manual or paperwork/ instructions plus not in its proper packaging This product works perfectly for joining my 4 inch dust collection hose with the smaller hoses from my three old Shop-Vac models - "Aqua-Vac", "Original", and "12 Gallon Heavy Duty Wet/Dry". 5kg dumbbell discs from the hooks and it didnt bend and the plate stayed perfectly affixed to the door.
