German carbon manufacturer Mcfk produces some of the finest bicycle components available today. With their meticulous attention to detail and quality control, Mcfk produces an impressive line of components that are not only lightweight, but strong and reliable as well.
With the road disc brake platform becoming ever more popular, Mcfk decided to design and produce rims specifically for this emerging market. Through specific layering techniques, Mcfk has achieved astoundingly lightweight rims that are more durable and perform better than many other heavier options. Where many rims are manufactured by bonding several sections together, Mcfk has chosen a monocoque construction method, laminating and curing the rim as one single piece. This method is labor intensive and more difficult to complete, but the end product is a stronger, lighter rim with less variance in resin volume and wall thickness. Designed for disc-only applications, these rims can be made significantly lighter compared to traditional rims with a braking surface.
These 55mm deep rims are ideal for larger, more powerful riders who desire a road disc wheelset with greater radial stiffness and improved aerodynamic performance. The impressive light weight of these rims allows for wheels that retain the dexterity and quick acceleration of shallower rims despite their large stature. Additionally, deep rims such as these take up more of the wheel's overall structure, reducing stress on spokes and staying reliably true over a longer period of time. Mcfk's asymmetric design allows for more even spoke tension across the wheel, leading to increased durability and less lateral flex. Mcfk rims feature laminated spoke holes which are stronger than the drilled holes found on many competitors' rims. Fully tubeless compatible, these rims have a proprietary valve seat design. This allows the valve head to sit lower in the rim making tire installation easier and faster. While this technology was implemented for tubeless systems, it also makes tire installation with tubes less of a hassle. Stacked with features, Mcfk rims are some of the finest rims on the market that offer riders a premium option when building a custom wheelset.
Mcfk rims are covered by a two year warranty that covers defects in materials and workmanship.
For their road disc rims, Mcfk recommends a tire width of 25-35mm.
We recommend that wheels with Mcfk carbon rims be assembled by an experienced wheel builder. Mcfk recommends a maximum spoke tension of 110 kgf, with an average of 100 kgf. Tubeless tape with a width of 19mm is recommended, paired with 65mm long tubeless valves.
