Reviews over the

Shimano Ultegra R8000

Product arrived with little fluidity, I thought it would improve after a while but on the contrary the grease started to come out of the axle, result hard point, the bearings are certainly out of order in less than 3000km and mantel for only answer tells me that it is not guaranteed and that I only have to go to my bike shop... Disappointed with the product and with mantel
