HED numbers its carbon wheelsets in sequential order, and while the Stinger 7 falls smack between the Stinger 6 and 9, it's not placed there on depth alone. The Stinger 7 FR Carbon Tubular Road Wheelset has been specifically designed to be a step above the Stinger 6, which is a well-rounded race wheel, and its accolades hail from it being a dangerous weapon under a capable sprinter. Yes, it's true that HED engineers reinforced the sidewalls of the 75mm-deep carbon rims, making them extremely stiff and responsive and an obvious choice for a powerhouse like Cavendish or Greipel. But what sets the Stinger 7 apart from other wheels optimized for those last few blistering seconds of a race, and adds to its versatility, is HED's Stability Control Technology which handles all of the other kilometers leading up to those final 200 meters. SCT specifically addresses the Stinger 7's shape to improve stability in crosswinds, thus countering one of the biggest drawbacks to running deep section wheels. In addition to Stability Control Technology, HED engineers also incorporated C2 Technology into the Stinger 7. C2 stands for two Cs: lower coefficient of rolling resistance (Crr) and better aerodynamics (Cda). The rims on the Stinger 7 Wheelset are 28mm wide when most rims are around 23mm, and it makes a big difference. A 28mm rim paired with a 23mm tire changes the tire's footprint. It grips better in a straight line, and it grips better in turns because the tire has a straighter sidewall and deforms a bit less at a given pressure. A 23mm tire on a 28mm rim also has lower rolling resistance. HED sent the wheels to Continental Tires for testing. Conti's engineers shrugged their shoulders and figured there was no difference, but they put them in their testing jig and ran the tests anyways. As it turns out, Hed's C2 rim design offers 18% less rolling resistance than typical narrower rims. And because of the smoother transitions from tire tread, to sidewall, to rim, and fina...
