The Speedframe Pro Helmet has earned Virginia Tech's best rating (5 STARS) in its Bicycle Helmet Ratings program. Designed with input from our pro mountain bike athletes, this top-tier open-face mountain bike helmet offers a market-leading feature set.
Unique four-sided design provides extra strength and support and helps prevent slipping and deformation of aluminum nipples. Uses the same world famous design and high quality materials as our three-sided spoke wrenches.
