Sena C1 Cycling Smart Communication Helmet

The C1 is a cycling helmet for riders who want tunes, directions and calls without ear buds. It has a 4-way Bluetooth intercom for chatting with up to three riders, and pairs to a smartphone for music, GPS and fitness prompts.

Compared with other options: it is a lower price step into the Sena lineup than the Mesh models, and it uses Bluetooth intercom rather than Mesh. That makes it a good fit for a small, regular riding group rather than a large, spread-out one.

• Intercom: 4-way Bluetooth
• Phone pairing: music, GPS, fitness cues, calls
• Sizes: Medium, Large; colors: Matte Gray, Matte White

Fit note: available in Medium and Large only, so check your head size first.
