The "Flat 90" is available as a "+ Flat 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 wheelset "+Flat 90" is specifically for Velomobiles with open wheel houses as DF and DFXL
InterCity bikes and K, Ks and EvoR.
You can equip it with carbon caps of Beyss light vehicles and intercitybikes.
The wheels have an increased braking power and heat absorption by the use of 90mm drum brake
hubs instead of 70mm hub.
Should the velomobile wheel houses, like the "pants" from. InterCity bikes are assembled, we can
make the wheels 5mm inside spoke. Thus, the turning circle is obtained.
Application finds an outside turned silver drum brake 70mm with silver DD Laser spokes and silver
anodized aluminum nipples.
The drum brake used, specially made for us
smaller spoke holes. This ensures a perfect fit of the particular
slight Sapim DD Laser spokes. Additionally a spacer between the bearings made of aluminum is used.
This saves weight.
