- Rim: Low profile full carbon
- Carbon/Alloy hub with oversized alloy axles
- CULT ceramic bearings for speed and longevity
- Spokes Front: 22 radial
- Spokes Rear: 24 with 2 to 1 technology
- Compatibility with Campagnolo, Shimano and Sram drivetrain systems
- The weight of the wheels does not include the quick release, and it refers to the lightest configuration
- Wheels come supplied with wheel bags, brake pads and skewers
- Weight (g): 1280

Exemplary results: they improve the lightness, the rotation fluidity of the hubs and their life over time. The low profile rim is available for tubular or clincher tyres. It is fitted with 22 radial spokes on the front wheel and 24 on the rear with doubling of the spokes on the freehub side (Two-to-One technology) to obtain a snappy response during sprints and uphill. The carbon hub is strong and makes it possible to save weight compared with the aluminium version.
Ceramic Ultimate Level Technology, CULT™. It's the new technical advancement adopted for the most revolutionary crankset in the Fulcrum® range, the Racing Torq™RRS, an unprecedented system which guarantees performance at the maximum level.
As well as using the best ceramic ball bearings on the market, a new treatment for the races and bearings has been developed with Cronitect® steel using advanced technology from FAG. This leads to the maximum level of resistance to corrosion so that no grease is needed for lubrication.
Get used to this acronym. It stands for Ceramic Ultimate Level Technology. But, above all, it is the technology we have developed, fine-tuned, and then adopted exclusively for the realization of the very latest bearings with ceramic balls.
Behind CULT™ is the exclusiveness of Cronitect® steel, with Advanced technology by FAG, used for the bearing races. This is a martensitic steel with exceptional hardness and resistance to corrosion, exalted by a thermo-chemical treatment of the surface layer.
Extremely high resistance to corrosion: Cronitect® has achieved exceptional results in the salt spray fog test and stands out on top from the other stainless steels.
CULT™- Cronitect® synergy guarantees that your Fulcrum® wheels will never encounter any problems with these new bearings.
When you push on the pedals, the rotational force on the sprocket induces a slackening of the freewheel spokes with a consequent loss of rim tension. This results in undesirable flex of the whole wheel and an unavoidable loss of energy.Fulcrum® has solved this classic cycling problem with its 2:1 Two-to-One™ Spoke Ratio patent, by doubling the spokes in the critical zones.
As a result there are two spokes which carry out the function of one, slackening and torsion are limited and the transfer of the athlete's power is much more effective Also, thanks to this system, spoke tensions are balanced more evenly between drive and non-drive sides and the fatigue life of the rim, hub and spokes is lengthened.
With the new Fulcrum® freehub body dedicated to non-Campagnolo® drivetrains you will be able to exploit the maximum versatility of your current system. We have developed a freehub body that is perfectly compatible with Shimano Inc. 8, 9 and 10 speed systems and Sram Co. 10 speed ones.
About the Fulcrum brand
There is a huge Italian tradition of cycle engineering excellence and Fulcrum was born from the very heart of it. Competition testing with world level athletes and the expertise Fulcrum's engineers possess means Fulcrum have become known for developing unsurpassed products with excellent performance, durability and market leading innovation. Key technologies pioneered by Fulcrum include 2:1 Two-to-One™ Spoke Ratio, which delivers incredible power transfer by doubling the spokes on the critical drive side of the wheels so no energy is wasted. Fulcrum has also focused on class leading rolling resistance through their CULT and USB Bearing Technologies which use ceramic bearings and cutting edge surface technology to massively reduce friction. CULT ball bearings are 9 times smoother than wheels with traditional bearings. All this innovation and technology has produced amazing results for everyday riders and pros alike with 4 world champions in just 6 years, Boonen, Bettini (x2) and Ballan.
