The Seka Spear is a lightweight, aero-optimized road frameset from a Chinese brand, gaining popularity for its performance and value. It features a carbon fiber construction with a unique 'Wind Eye' seatstay design for claimed vibration damping and aerodynamics. The frameset includes an integrated Rapier cockpit and is available in standard and RDC (Race Design Carbon) versions, with the latter using higher-modulus carbon for reduced weight. Key attributes noted by users include competitive weights (e.g., ~800g for a medium frame in Chronos color, ~815g for Large Shadow Black, ~910g for XL Cronos), BSA threaded bottom bracket, and a max tire clearance of 32mm (though some users fit up to 35mm tires on specific rims, with tight clearance). Pricing is generally lower than Western brands like Specialized SL8, but availability can be limited with long lead times. Ride impressions highlight a stiff, responsive feel good for climbing and descending, with comfort praised by many, especially in the rear, though some report a harsh front end, disc brake rub, or road buzz. Users have achieved very low build weights, with complete bikes around 6.2kg and extreme RDC builds as low as 4.96kg. Quality control issues include misaligned components, seatpost wedge fit problems, and handlebar wobble in crosswinds, but warranty support is available. The frameset supports various computer mounts, though compatibility may require adapters for devices like Hammerhead Karoo. A new TT frame with Wind Eye design has been released. Sizing advice varies: some users size down with spacers for agility, while others match geometry to existing bikes.
AI Summary
Pros
- Lightweight for an aero frameset, with RDC versions around 800g for medium frames
