Knife Disc Rear Wheel

The TUFF Knife solid disc wheel uses a super rigid and lightweight “honeycomb” structure using technology developed for the aviation industry.
Strengthening the wheels internally allows weight reduction and freedom to shape the wheel exterior for better aerodynamics –
the sole purpose for upgrading to a disc wheel. When the bike leg can make up 40% of race time during a Triathlon,
or when pure aero efficiency is required for a TT, you don’t want to compromise on equipment choices.
