Bike setup: every field and what it drives, Yousuli Help

What a BikeSetup is

A BikeSetup row represents one bike that an athlete owns and uses. Athletes can have multiple bikes (race TT bike, training road bike, gravel, indoor trainer, etc.). Each bike has its own fit measurements, components, position values, and history.

Coach side: edit a bike at /coach/bike-setup/<bike_id>/edit/ or create one at /coach/bike-setup/new/. List them on the equipment hub: /coach/athlete/<public_id>/equipment/.

Athlete side: read-only summary on /my-equipment/.

Identity

Name: short label like "Race TT" or "Training Road".
Bike type: TT / Triathlon, Road, Gravel, Track, Indoor Trainer, Other.
Primary flag: is this the race bike?
Athlete: which athlete this bike belongs to.

Frame and components (free text)

These are recorded as plain strings so you can be as specific as you want without the Hub enforcing a brand list:

Frame brand / model / size.
Front wheel / rear wheel: brand and model, free text.
Front tire / rear tire: brand, model, width.
Groupset: e.g. "Shimano Ultegra Di2".
Pedals.
Saddle.
Helmet: the helmet typically used with this bike.

Fit measurements (decimal fields)

Each is optional but the more you populate, the more you can recreate the position if it gets disturbed:

Stack (mm): frame stack height.
Reach (mm): frame reach.
Pad width (mm): aerobar pad width.
Pad stack (mm): pad height from BB.
Crank length (mm): e.g. 165, 170, 172.5, 175.
Saddle height (mm): from center BB to saddle top.
Saddle setback (mm): horizontal saddle offset.

Performance values

Tire pressure front / rear (PSI): what you ran most recently.
Total weight (kg): bike weight with current setup.
Last CdA (m squared): the most recent measured CdA. See CdA Field Test.
Last Crr (rolling resistance coefficient): e.g. 0.0040 for fast race tires.

Notes fields

Position notes: free text for extensions, bar angle, cockpit specifics.
Notes: anything else worth remembering.

Why each section matters

Fit measurements let you reset the position after travel, a fit session, or component swaps.
Performance values are inputs to the Bike Power Plan calculator (weight + CdA + Crr drive the projected bike split).
Components matter for race day check (is the right cassette on the right bike? is the helmet allowed at this race?).
Position notes let a new coach pick up an athlete's fit without losing context.
