Extremely lightweight, aero carbon wheel!
The target of the development was nothing less than providing the best rim for fast and light-weight disc bikes. Nothing but the best!
For this purpose, Mcfk matched every parameter, every detail of the rim meticulously and did their utmost to develop the very finest for you.
- Carbon for the rim
In contrast with aluminium, the advantage of carbon is that it stays in form. Thus, recentering, height and lateral runouts are things of the past. Once spoked properly, the wheel will not change shape or run.
- Multiple layer design
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
Avoiding weak points was one of the central focal points in the development. Whereas Mcfk's competitors make the rim by bonding several parts together, theire rim is laminated of a single piece and cured. This involves a higher input of time and effort and requires extensive know-how but adds stability, saves weight and produces a homogeneous rim.
- 26.5 mm outside width
The wider the rim profile, the higher the lateral stiffness of the wheel.
The flexural rigidity increases disproportionately (to the third power) of the width of the profile. Mcfk's oversize rim profile on downhill rim level obtains stiffness never before attained with wheels of this weight class.
- 3.5 mm asymmetry
A very important aspect of the outstanding stability of Mcfk's wheels is the distinct asymmetry of 3.5 mm. 3.5 mm asymmetry is the reason why the difference of the inevitably non-symmetrical position of the hub flanges to the hub center is reduced by 7 mm.
This ensures uniform spoke tension on both sides of the wheel.
- 17.5 mm inside width
The new wider tires require a wider rim. Both should make a good match otherwise the tire tends to cant and does not instill confidence while riding.
- 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 Mcfk's carbon rims is extended.
- Laminated spoke holes
Another very important advantage of their rims is the pre-compacted, laminated spoke holes, which are not drilled. This means no cutting of fibers, high spoke tension and therefore even more stability for the wheels.
Besides, it gives the rim reliable protection from spoke tear-out in the case of a fall. You simply have to replace a couple of spokes but never the complete wheel.
- 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
The advantages of the tubeless technology can now be exploited to the full. Lower inflation pressure provides better grip, traction, comfort and riding pleasure. The rolling resistance is reduced and propulsion guaranteed. Mcfk's rim base is suitable for tubeless ties of all common makes.
- Integrated valve design
A special design at the valve seat makes the valve head "disappear". This technology has been developed specially for the application with tubeless tires. This makes mounting the tire with pre-installed valve a lot easier. Even non-tubeless tires are easier to fit.
- Disc only
By dismissing the brake flanks Mcfk are moving with the times. The future of deceleration in cycle racing and cross-country events belongs to the disc brake. No heat is transferred, for example, on long, steep downhill tracks - safety profits. Scraping noise and reduced braking in rain and muddy ground are things of the past. The rime does not wear and you can enjoy it for a long time.
The name of an Gorilla, weighing a ton, might sound a little martial for lightweight hubs. But it is strong as his namesake: No limit for biker weight.
Unique construction: due to adjustable play no bearing deadlock even at hardest lacing. Solid, uncomplicated, high-quality materials and precision bearings. Perfect manufacture - and absolut robust even under hardest conditions.
Tune uses special bearings which are like that not available on the market! The bearings identify themselves through a special grease and a higher filling degree. Besides o fit they are double abradant sealed and maintenancfree.
The wheel comes with mounts for 15x100 mm thru axle front. Using optional Tune end caps can also be realized other standards.
Maximal system weight 125 kg!
