We work with the fastest racers in the world to create products that help them win the biggest races in the world. Then we make those products available to all riders so they can realize the same performance benefits as the pros.
The S-Works TT 5 helmet is an excellent example of our Made In Racing approach. Remco Evenepoel and Kasper Asgreen of Quick-Step Alpha Vinyl logged countless hours in our Win Tunnel until we arrived at the fastest TT helmet we have ever made.
Using CFD modeling, the helmet team reshaped the TT helmet, positioning the rear of the helmet to be nearer the rider’s shoulders, reducing the eddy of air that creates drag.
The S-Works TT 5 helmet comes equipped with a Class 1 optics shield for zero distortion when looking down the road, unlike traditional lenses that are typically drape-formed with clear plastic. The shield has a hydrophobic coating to help clear moisture away if the weather turns bad on race day, as well as a high-grade (EN166) anti-fog coating.
The Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape and helmet angle can be adjusted for compatibility with glasses. An adjustable Tri-Fix web system gives riders added comfort with updated, thinner 10mm webbing that minimizes strap noise.
Our ultralight and supremely comfortable MIPS Node Air technology is integrated directly into the helmet padding, with a sleek low friction layer designed to dissipate rotational forces. With Specialized’s proprietary development work, we added perforations to maximize breathability, performance, comfort, and weight savings.
For helmets sold in the U.S. and Canada: Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older.

Tool was exactly how described and packaging was nice. It did take a few days to ship so unfortunately I didn’t receive it in time for the trip I ordered it for which is the reason for 3 stars but I received it the week after and it’s coming in handy.
size is big enough and clear simple layout. moved from garmin 850. I am very satisfied with wahoo!
Sierra is no joke, this is our 4th bike in the last 3 months and the process has been so easy, they are fair with pricing and never make it feel transactional! I won't be buying anywhere else!
