Extremely lightweight 29er Carbon Boost-wheelset!
Lovingly made in Leipzig with DT Swiss 240s hubs, J-bend-spokes
and the outstanding Mcfk 29 inch MTB bike rims with 25mm
or either 35mm inner rim width for 29 inch-plus-tires
The wheels are manufactured manually in an elaborate process with meticulous perfection by Mcfk´s own wheel specialist. Before shipment, each wheel is checked again. Perfect true running and the uniform tension of all spokes are of particular importance.
- Carbon for the rim
When compared with aluminium, carbon has the decisive advantage that it hardly changes its shape. Consequently, the runner wheel is distinctly more long-lived and less susceptible to side or radial run-out.
- Complex layer structure
No two types of carbon are alike. The layer design is the decisive aspect - the orientation of the fiber is the most important thing in any part made of carbon. For this reason, Mcfk use a complex mixture of fabric and unidirectional (UD) layers which are positioned exactly in the right direction to ensure that they get the best performance of the material and leave no potential unused.
- Monocoque design
A very important aspect of the development was the avoidance of weak points. Mcfk´s wheel rim is laminated and cured completely in one piece. This may require a higher level of effort but it adds stability, saves weight and makes a homogeneous rim.
- 35 mm or 44 mm outside width
The wider the rim profile, the better the lateral stiffness of the rim. Mcfk´s wide rim profile ensures outstanding stiffness levels of runner wheels in this weight category. Force transmission with no force loss– you will feel it, e.g. when riding out of the saddle.
- 29 mm height
The height of the rim profile decides the radial stiffness. Radial loads to which the rim is exposed on uneven ground, by bumps or bottoming are reduced by a high profile. The load on the spokes is hardly reduced, which increases the life of the structure directly. These rims with 29 mm height are the perfect compromise of stiffness and weight. Agility riding and acceleration quick as lightning during sprints are promised.
- 3.5 mm asymmetry
3.5 mm asymmetry are responsible that the difference between the hub flanges, whose position to the hub center is obviously asymmetrical, is reduced by 7 mm.
The lateral spoke angle and the spoke tension on the right and the left side are adjusted by the asymmetry. Stiffness and life profit from this geometrical intervention.
- 25 mm inside width
Ideal for tires up to 60 mm width. The inside width of 24.5 mm forces the tire into an ideal shape in which it is supported more effectively on the rim. You can reduce the tire inflation pressure. Cornering stability and traction improve and off-road rolling resistance is lower.
- 35 mm inside width
Ideal for tires up to 75 mm width. The inside width of 35 mm forces the tire into an ideal shape in which it is supported more effectively on the rim. You can reduce the tire inflation pressure. Cornering stability and traction improve and off-road rolling resistance is lower.
- Rim flange with extra stability
The unique ratio of outside and inside widths also adds extra stability, width and solidity to the wheel flange. Bottoming - the enemy of any light-weight rim - need no longer be dreaded and so the life of Mcfks carbon rims is extended.
- Laminated spoke holes
Another important advantage of Mcfk rims is the pre-compressed laminated spoke holes, which are not drilled – this means no fibers are cut through, which adds even more stability to the runner wheels. Besides, it protects the rim from spoke strip.
- Preformed ball head nipple tip
To ensure a perfect fit of the nipples in the rim, they need the right nipple seat. Because Mcfk do not drill the spike holes but compress and laminate them, they can shape a perfect ball head in the rim.
- Tubeless-type rim well
Tubeless offers a number of advantages. Flats are rare – snake-bites are a thing of the past. Lower inflation pressure provides better grip, traction, comfort and riding pleasure. The rolling resistance is reduced and propulsion guaranteed. The rim base is suitable for tubeless ties of all common makes.
- Max. system weight: 125kg
DT Swiss240s hubs
The DT Swiss 240s is one of the top hub for light wheelsets. The aluminium hubs are 100% swiss made for world class precision and quality.
The advantages of the 240s are their extremely low weight, their high-class contact free double flange seal system against water and dirt, their bearings made of stainless steel and a special coating which guarantees for smooth rolling characteristics.
