The Fulcrum Speed 40 CMPTZN carbon wheelset is inspired by the competition wheels of the World Tour pros. The carbon rims are extremely light and enormously stiff due to the two-to-one lacing pattern, which gives your road bike excellent acceleration behaviour. The CULT ceramic ball bearings impress with excellent smooth running and are extremely durable. The 19 mm inner rim width allows you to choose from a wide range of tyre widths from 23 mm to 50 mm. Just choose according to the terrain you want to ride. The wheels are tubeless ready, so you can decide for yourself whether you want to ride with or without a tubes.
Ceramic Ultimate Level Technology for ball bearings is characterised by particularly hard, corrosion-resistant stainless steel, whose top layer is extremely resistant. The abrasion remains very low, and only a thin layer of oil is required for lubrication, so a lot of grease can be left off. This allows the ceramic balls to follow their path very precisely.
Undrilled Rim Bed
The rim bed is continuous and has no holes for nipples. The nipples are inserted over the valve opening and guided with a magnet to the connection point of the rim. This eliminates the need for rim tape, increases the durability of the rim and allows the spokes to be tensioned more, resulting in greater stiffness.
Two-to-One Spoke Ratio
In order to avoid energy loss, two-to-one wheels are equipped with double the number of spokes in critical areas. In the case of rear wheels, this takes into account the increased forces on the drive side. Front wheels have twice as many spokes on the side of the brake disc.
