Description: While the grade of materials and the surface treatment of the races may change between groups, one thing is constant. Shimano hubs exclusively use a cup and cone bearing system in all of its hubs. Cup-and-cone bearings offer greater strength than sealed cartridge bearings due to their ability to displace lateral and vertical loads more effectively for super smooth rotation in real world riding conditions. Cup-and-cone bearings also allow for easier maintenance, adjustability and serviceability. | | Features | | * Super lightweight & rigid alloy axle | * Radial lacing compatible | * Smooth rolling | * Double Contact Sealing | * Regular Hole: 24/28/32/36H | * Aero Spoke Hole: 18/24/28/32/36H | * Weight: 188g (59g QR) | | Specifications | Model Number HB-7800 | Series DURA-ACE | Over Locknut 100mm | Axle Type 108mm | Stainless Steel Ball Bearings yes | Contact Sealing labyrinth and contact seals | Spoke Holes 36,32,28,24 32,28,24,18(areo) | Spoke Hole Circle 40mm | Hub Shell cold forged aluminum/anodized | Center to Flange (Right) 37.0mm | Center to Flange (Left) 37.0mm | Average Weight w/o QR 129g (59g QR)
