Roata SET ROTI FULCRUM RACING 5 DB DISC CENTER LOCK Ax 12-15-QR/12-QR Negru #43441

Racing 5 DB is a bicycle wheelset that is all about substance and it certainly is brimming with it thanks to a series of key technical features that give this model versatility.This aluminium wheelset begins from solid foundations that are brought up to date with the latest trends: The 17C rim groove fits perfectly with 25 mm clincher tyres, while the low asymmetrical profile of the wheels gives them agility and adds responsiveness, combined with almost effortless steering.In addition, R&D has included some technical details that are trademarks of Fulcrum's products: aside from asymmetry, which is important for balancing the forces exerted by the hubs, the discs and the cassette, these aluminium wheels have the added benefit of a straight head spoke structure for increased stiffness, reactivity and power transfer.PropertiesAymmetric rim profile: The asymmetrical rear rim profile allows for better balancing of spoke tensions between drive and non drive side, giving better symmetry to an asymmetric component. Advantages: increased efficiency and reactivity are sure to be noted.Rim with oriented drilling of spoke seat: For increased stability.Stainless Steel spokes: Provide high levels of tension and stiffness.High grade, top quality steel bearings with cup and cone construction: Reduce friction and ensure consistent performance over time.Technologies2Way - Fit™ Ready (Road)This procedure transforms Racing 4/5/6/7 DB and Racing 400/500/600/700 DB wheels (designed to be used with a clincher tyre and inner tube) into Tubeless Ready wheels (no inner tube and compulsory use of a sealant liquid).AFS System™The Axial Fixing System™ is the solution developed by Fulcrum® to fix the disc brake to the hub. The constraint granted by the butt area of the release mechanism, greater than in familiar standard ones, makes it possible to obtain greater structural rigidity and therefore more precise and powerful braking.Disc Specific RimFulcrum® is one of wheel manufacturers on the market to offer two completely different rim profiles from disc to conventional brake. So, no adaptation, but a rim conceived based on years of design experience. Not requiring a braking track, Fulcrum®’s R&D department designed a completely new profile, aimed at saving every single gram of weight and at improving aerodynamic efficiency. Its greater width makes it a perfect fit for tyres of 25/28mm upwards.Monoblock Disc HubThe rear hub of a top-quality disc brake wheel is a technical problem to be solved. Fulcrum®’s R&D department found itself facing a fundamental choice: on which side to put the oversize flange of the Two-to-one™ system? Disc or sprocket side? Without question - must stay on the sprocket side.To combat the loss of braking power from flex and torque of the connector between the two sides of the hub, a special one-piece system has been devised with internal stiffening ribs.The Anti-Rotation System™ is designed to make sure that spokes will never lose their initial tension and remain in the position that have been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.Note: Shimano 9/10-speed only with 1 mm spacer which is included with the cassette.Product Name:Fulcrum Racing 5 DB Wheelset - Clincher - AFS - VR: 12/15x100mm/QR | HR: 12x135/142mm/QRManufacturer:FulcrumYear:2018Manufacturer item code:RC5-18DFR22AMaterial:rims, hubs: aluminumspokes: stainless steelWeight:approx. 1610 gram (per set)(manufacturer information)Rim height:FW/RW: 26 mm (asymmetrical)external/internal rim width:external: 21.8mminternal: 17mmE.T.R.T.O.:17-622Spokes:round2,0 mmSpokes number:FW: 24 (16 links + 8 rechts)RW: 24 (8 links + 16 rechts)Hub axle system:FW: 9x100 mm QR | 12x100 mm thru axle | 15x100mm thru axleRW: 10x135 mm QR | 12x135 mm thru axle | 12x142 mm thru axleFitting type of tire:clincherFitting tire dimension:width: 25mm - 50mm (manufacturer recommendation)Fitting for shifting:Shimano 8/9/10/11-speed HGMax. permissible total weight(rider + bike):109 kg (rider)Color:rims, hubs, spokes: blackdecals: whiteDisc brake standard:AFS
