The "black 90" is available as a "+ black 90". He thus becomes a real high performance wheelset.
By arranging the heatsink best heat dissipation is ensured without structural weakening of the hub.
The heatsinks are specially manufactured for use in the drum brake hubs and increase the cooling
surface to 800 cm² per wheelset.
The "+ Black 90" has in principle the same basic parameters as the "+ Silver 90".
The wheels have an increased braking power and heat absorption by the use of 90mm drum brake
hubs instead of 70mm hub.
The black anodized surface, the heat radiation is improved. Anodizing also avoids corrosion of the
hub surface, but especially in the compound spoke hole / spoke head. The spokes keep so even
under salt exposure at all-season use a very good seat.
The black appearance makes it look very classy him to trikes and unclad vehicles.
The wheelset we built with black hubs, black spokes and black-DD Alunippeln. We are happy to
build the Black with colored nipples. This underlines the individual configuration and makes the
wheels into real eye-catchers.
The drum brake used, specially made for us
smaller spoke holes. This ensures a perfect fit of the particular
slight Sapim DD Laser spokes.
From now the wheelset is constructed with different rims.
This is necessary to cover all areas of application.

Fratelli FX18XCR, tubelssready
Tire width 23 - 35 mm, permissible total vehicle weight 28 holes 110kg
All wheelsets are built, centered and tested completely by hand. Wheel protocol and rim tape are included in the price.
All wheels are signed in the bottom of the rim and recorded in our database.
In the event of damage, the necessary spare parts can be ordered quickly using the wheel number.
The wheels can be completed with our carbon wheel discs with an 80mm inner bore.
Conversion to a 15mm axle is also possible. If necessary, please include this in the comments.
