We base our design on road. We design the geometry to meet the needs by riders. For three years of development, we have been collaborating with labs and pro riders, taking untiring actions to fine tune the bike that brings you to the podium.

Innovative High Performance Composite

We create from zero, setting our goals and the path to there. We choose the best raw material by Toray. We develop the fundament and structure with our engineers of decade-long expertise. We push ourselves up to high standards, and achieve them Finite Element Analysis to optimize lamination, geometry and cross-sectional contour of our bikes, delivering a perfect balance between stiffness, lightweight and compliance. IHPC has been borne in mind by our engineers, designers, manufacturers, and test riders, throughout the entire cycle from design, simulation analysis, manufacturing, real word testing, to making the end product. Now you have a SEKA product which incorporates our effort behind every scene.

Functional Geometry System

We have our own philosophy about geometry, integrating our knowledge and experience in ergonomics into the design. Functional Geometry System (FGS) makes the bike an extension of your body. We adjust the cockpit to suit most riders’ position with greater stack to reach ratio and stems at less aggressive angle so that spacers are no longer a need. It realizes an improvement in front end stiffness, integration and tidiness in look, handling precision, and comfort in long rides. FGS turns the bike into an extension of your limbs.

Asymmetric power transferring structure

The asymmetric power transferring structure creates a stabilized, efficient and balanced platform by specializing the profile, material and lamination of different areas in areas carrying massive force. We manage to solve the torsional gap between left and right, enhancing the integrity of bottom bracket and chainstays to provide exceptional overall pedaling efficiency.

Vibration filter

By the thinning seatstays design and IHPC optimization, Afield ensures racing-ready performance with improved comfort, smoothing out the vibration during fast cruising.


SEKA Afield is eligible for events on your UCI calendar.

We choose the best materials to maximize the performance.
