New Trek Helmets - Ballista & Velocis

Where’s the wind tunnel data

I bought one. Either it is cooler or the sweat is evaporating better (better cooling??) or the sweat is not as noticeable dripping more too the side…whatever it is, the Limar speed won’t be used until it’s cool again in the fall.

More subjectivity…I appreciate the move away from wavecell. I thought that made the helmet hot more than anything (I have a Bontrager Circuit as well). And not being able to perch sunglasses was annoying. I’m happy to announce the new Velocis has no wavecell and therefore the perchability of glasses is back to normal. Weird how you notice something more when you don’t have it.

Further subjectivity…the back of the helmet has narrowed compared to older versions. I like the look. Whether relevant or not I like the look of low profile helmets and this one checks the box. I think it’s more how my head fits into the helmet vs. the helmet being super low profile though. One thing is for sure, it’s not as thick as a year old Bontrager Circuit.


Has anyone who owned an older Velocis helmet has gotten the chance to try on the new model. I’m wondering if the fit is still the same or if it has been updated. I currently ride the old velocis in M but am at the upper limit and I‘m very happy with the way it fits. Wondering if it’s safe to assume the new one should fit just like it.

I read in their latest iteration Specialized have changed the fit on their Prevail & Evade helmets to a tighter fit and some people had to size up when changing to the newer model. Wondering if this is the case for the Velocis model. I‘d hate to upgrade to an L because for most L helmets I’m on the lower size limit and they fit like a bucket.

I’m a M in both the old and new versions. The new helmet is more comfy. The new helmet feels it might fit a slightly larger head in it, the cradle seems to have a bit more room. But once tightened up it’s solid.
