Back in 2019 Bontrager introduced WaveCel to their helmet line, a collapsible cellular structure that works like a crumple zone to help absorb both rotational and linear impact forces before they can reach a rider’s head. Today they announce the addition of three new models to their line. This comes in response to customer requests for sizing in extra-large, a version for kids, and a less expensive model.
The three models include:
- Starvos WaveCel Cycling Helmet
- Rally WaveCell MTB Helmet
- Jet WaveCell Kids’ Helmet

I’ve been using both the XXX (aero) and Specter (road) since Bontrager introduced the WaveCel helmets. Last week the team at Trek sent me the Starvos model to test. I’ll share a complete review once I’ve had plenty of ride time and plan to compare it to the Specter.
There are some subtle differences between the current WaveCel helmet line, and the new models released today. Per the company, the WaveCel insert of Bontrager XXX, Specter, Blaze and Charge WaveCel helmets covers the front, rear, top and sides of the internal area. The WaveCel insert of Bontrager Starvos, Rally and Jet WaveCel helmets covers the front, top and sides of the internal area, while the rear is EPS and may have properties similar to EPS helmets.
If you’ve been looking to buy a WaveCel helmet, but holding off because of the price, here’s some initial specifications and differences to help you decide.

Bottom Line
If you’ve been wanting a Bontrager WaveCel helmet but found it out of your price range or you needed an extra-large, now is the time to take another look. Yes, there are some slight differences which enable a lower price point, but that’s to be expected. However, these are still safe, comfortable helmets. Stop by your local Trek dealer to try one out for yourself and share your thoughts. Once I get some ride time with the Starvos helmet, I’ll post a full review.
Thanks, Shari Rosenbaum. Your reviews are very helpful. Wondering if you have any updates on the Bontrager Starvos vs Specter helmets. I ride in the city and suburbs for pleasure only. Although I am in search of some of the best head protection I can find (TMI: I am on a blood thiner) I am also price conscious and don’t want to over buy. Any/all additional info you have beyond the good review you did previously, would be much appreciated. Thanks and happy biking,
Hi Ed,
According to Virginia Tech, the Specter costs $150 and scored 5 stars with a score of 10.8 (lower is better). The Starvos is available for $100 and scored 5 stars with a score of 11.2. Either will serve you well, go for the one that you like the look of and is in your budget.
