Helmet Fit Guide: Which XEcycle Camera Mount Fits Your Lid?

A camera mount that "fits most helmets" fits none of them well. Aero road helmets are all compound curves, and every brand sculpts them differently — so we model each mount around one specific shell. Here's the current fit list, with the details that matter.

Specialized

S-Works Evade 3 and S-Works Evade 4 are both supported — but pay attention: the two shells are different and the mounts do not interchange. If you upgraded from Evade 3 to Evade 4, you need the matching mount. When ordering, double-check which generation you own (the Evade 4 launched in 2025; the easiest tell is the vent layout at the front).

KASK

  • Utopia — our mount for the Utopia shares its bolt pattern with the Prome PL21, so PL21 riders can order this option too.
  • Elemento — KASK's flagship gets its own dedicated shape.
  • Protone — the classic. Dedicated mount, fits the modern Protone Icon shell.

Trek

  • Ballista — Trek's aero road lid, dedicated fit.

More brands

  • Sunrimoon 3DGrid — yes, the value favourite is fully supported.
  • XDS aero helmets — including the popular domestic aero shells.
  • Limar aero — supported via our multi-fit road option.
  • Van Rysel RCR — Decathlon's race helmet, as ridden in the WorldTour.

Don't see yours? Ask. New shells get added based on demand, and a request from you is how they get prioritised.

What's in the box

  • The TPU cradle shaped for your helmet
  • Zip ties for installation (pre-sized for the vent channels)
  • That's everything you need besides your camera's own magnetic clip

Fitting notes

  • Installation is tool-free: thread the zip ties through the vents, tension, trim.
  • The TPU is helmet-safe — it will not scratch the shell or stress the vents.
  • With the camera off, the cradle is low-profile enough for everyday riding; the clip quick-releases so your helmet stays a normal helmet.
  • Works with the DJI Osmo Nano and Insta360 GO 3S / GO Ultra (choose your clip type at checkout — see our clip guide).
