Typically, we think of aerodynamics as the science of reducing drag. You want as little resistance as possible from your equipment while you're producing as much power as you can on the bike. Zipp's Sub-9 disc throws that notion out the window by generating 80g of forward lift at certain wind angles when paired with our Tangente tire. Like a sailboat tacking into the wind, your equipment can actually propel you forward.
We've achieved the seemingly impossible by applying what we learned from developing the 1080 and 808 to what we already knew about discs. Ringed by our patented toroidal rim profile, the Sub 9's shape is an odd one but it works by controlling airflow at the wheel's leading and trailing edges. And just like our non-disc wheels, the Sub 9 absorbs impacts and vibrations from the road surface, making for a comfortable ride over a long bike leg.
- Weight: 1003g
- Track Adaptable: No
- Dimpled Surface: Yes
Variation in individual chain stay specifications on these bike models may cause interference issues with the Sub9. This is more of an issue for heavier and stronger riders (>170 lbs), but Zipp strongly recommends you test the compatibility under riding loads and conditions before making a purchase.
Also available with Powertap SL hub the Sub 9 is the ultimate race wheel when you can use power to gauge effort.
