SEKA — wind-tunnel speed, race-proven carbon
SEKA builds performance carbon frames around obsessive aero and materials science. The flagship Spear went through dozens of design iterations, CFD analysis, and repeated testing at the Silverstone Sports Engineering Hub with Aerocoach.
Tunnel data showed meaningful drag savings, helped by SEKA’s WindEye seat-tube treatment that also improves vertical compliance. Frames use true one-piece moulding and ultra-high-modulus carbon — light, stiff, and race-ready without feeling brittle.
PSC is now an official SEKA retailer. The ExAero RDC — first in the UK — lands this week, alongside Spear RDC and ExAero RDC GR.
- Spear RDC — road endurance, Silverstone validated
- ExAero RDC GR — gravel racing, 56 / 52 mm clearance

The journey
From brief to first ride
Every build is unhurried and personal. We keep the process clear so you always know what comes next.
- 01
Consultation
We talk through how you ride, what you want the bike to feel like, and any must-have details for geometry, components, and finish.
- 02
Fit-informed design
Your fit data and riding style shape the brief — so a SEKA frameset is sized and built around you, not a catalogue size chart.
- 03
Build & final fit
From assembly through setup, we finish with a precise fit so the bike feels right from the first ride.
Not sure which path is right?
Many riders start with a full bike fit on their current machine, then explore a SEKA frameset once they know what position works. We are happy to advise either way.
