The machine

Built for the boards

A track bike looks simple because every part has one job. No brakes. No shifting. No freewheel. This build guide breaks down Leo’s bike, what each component does, and why it earns its place on the track.

Full build sheet and bike photography coming soon. The component guide below explains the anatomy while every model and setup detail is verified.

  1. 01

    Frame and fork

    BXT TRC-195 carbon track frameset — size XS

    What it is
    A carbon fixed-gear track frameset for 700C wheels and tires up to 28C, with 10x120 mm rear dropouts, a BSA threaded bottom bracket and a 1-1/8-inch headset. The frameset includes the frame, fork, seatpost, headset and seat clamp.
    Why this setup
    Leo rides the XS TRC-195 as the foundation of his current track bike. Its dedicated track layout supports the rigid, direct fixed-gear drivetrain used for velodrome racing.
  2. 02

    Handlebars

    Alpina Enduro carbon track handlebars

    What it is
    A gloss-finished UD Toray carbon track bar with anti-slip paint on the tops and hoods. It uses a 31.8 mm stem clamp and measures 330 mm center-to-center at the drops, 236 mm inside-to-inside at the hoods, with 127 mm of drop and 105 mm of reach.
    Why this setup
    Leo’s current track bike uses the Alpina Enduro’s narrow, track-specific shape. The carbon construction provides a rigid control point for starts, sprinting and close racing on the velodrome.
  3. 03

    Wheels

    Build detail coming soon

    What it is
    Track-specific wheels built to balance aerodynamics, stiffness and predictable handling on the banking.
    Why this setup
    Leo’s wheel setup and the events it is selected for will be documented here.
  4. 04

    Tires

    Build detail coming soon

    What it is
    The bike’s contact points with the track, where casing, compound and pressure affect grip and rolling resistance.
    Why this setup
    The tire model and race-pressure approach will be added only after the setup is confirmed.
  5. 05

    Crankset

    Build detail coming soon

    What it is
    The crank arms and chainring that turn each pedal stroke into chain movement on a fixed-gear track bike.
    Why this setup
    The crank length and chainring choice will be explained in the context of Leo’s fit and events.
  6. 06

    Gearing

    Build detail coming soon

    What it is
    A single chainring and rear sprocket create one fixed ratio—there are no shifters, freewheel or brakes.
    Why this setup
    Race gearing changes by event and conditions; only confirmed, non-schedule-specific examples will be published.
  7. 07

    Chain and drivetrain

    Build detail coming soon

    What it is
    The chain and sprockets form a direct connection between the pedals and rear wheel, making smooth power transfer essential.
    Why this setup
    The selected chain and drivetrain setup will be described after the build is verified.
  8. 08

    Pedals and retention

    LOOK Kéo Blade clipless pedals

    What it is
    A clipless road pedal system that replaces a traditional steel retention spring with LOOK’s carbon leaf-spring blade and uses a broad cleat contact platform.
    Why this setup
    Leo uses the Kéo Blade system for secure foot retention and a stable pedaling platform during high-cadence efforts, standing starts and track sprints.
  9. 09

    Saddle and seatpost

    Build detail coming soon

    What it is
    The support and adjustment system used to establish a repeatable, efficient track-racing position.
    Why this setup
    The specific saddle, seatpost and fit reasoning will be documented with the rest of the build.
