All helmets sold in the U.S. must meet Consumer Product Safety Commission (CPSC) safety standards, so an expensive bike helmet will not necessarily provide better head protection than a cheaper helmet. However, performance bicycle helmets designed for serious cyclists have two things going for them -- they are very lightweight and have large amounts of ventilation. In this category, the Specialized Propero gets numerous recommendations for performance and value. The helmet comes in three sizes for a precise fit. Multiple reviewers say the Specialized Propero is very comfortable, and it is said to be a good choice for either road cyclists or mountain bikers. Specialized helmets can be found at local bike shops or online at Specialized.com. The Specialized Propero comes in both men's and women's colors. If you can't spend this kind of money on a bike helmet, reviewers also like the Bell Slant (*Est. $55). It's not as light or well ventilated as the Specialized Propero, but it's considerably less expensive.
The Specialized Propero helmet is reviewed by a number of sources, including RoadCyclingUK.com and Bicycling and Women's Adventure magazines. Each of these sources tests the helmet for fit and comfort, and RoadCyclingUK.com provides a pretty in-depth overview. In addition, the Specialized Propero helmet is reviewed briefly by Outside magazine. Unfortunately, there are few owner-written reviews available for this helmet.

The Specialized Propero gets 4 out of 5 stars from Simon Withers at BikeRadar.com. Withers is impressed that the helmet is certified by Snell, which means it has passed a variety of tests to determine the helmet's performance and ability to stay on the head in different environmental conditions - ambient, wet, heat, cold. He also calls it a "good value."
