IKUISTA Fit Recommendation
Bike:—
· —
Important: This tool provides a guideline recommendation based on the measurements you enter.
We cannot guarantee the recommendation is perfect — flexibility, riding style, saddle setup, and personal preference matter. Your final configuration and component choices (size, stem, bar, cranks, spacers) are always your responsibility.
How to measure:
Stand barefoot against a wall. Look forward. Measure to the top of your head.
How to measure:
Barefoot. Place a book firmly into your crotch (like a saddle) and measure from floor to the top edge. Most people are 65–95 cm — if yours is far from this, check you measured in cm, not inches.
How to measure:
Measure bone-to-bone across shoulders (acromion to acromion), not shirt seam to seam. Bar width is measured center-to-center (c-c).
Riding positioni
What this affects:
This slider affects frame size, stem and spacers. In a size-overlap zone a more comfortable position picks a bigger frame + shorter stem (higher front end); a more aggressive position picks a smaller frame + longer stem (lower front end).
Endurance
ComfortEnduranceRace
i
What this affects:
With clip-on aero bars your forearms rest on pads and your grip moves forward. We then recommend a shorter stem and, between two sizes, the bigger frame — a higher, more stable front end is easier to hold in the aero position. In aero use the saddle often moves slightly forward and up.
Extra measurement (optional)
How to measure:
Measure suprasternal notch (base of throat) → crotch (same point as inseam). Tape runs along the front of your body. This refines frame size and cockpit/stem. Most people are 45–65 cm — if yours is far from this, check you measured in cm, not inches.
How to test:
Stand with straight legs and reach toward your toes. Can't get near = stiff. Reach your toes = average. Palms flat on the floor = supple. This tells us how low a riding position you can hold comfortably.
Your recommendation
Recommended size:—
This is the bike frame size. Choose this when you order.
Saddle height:—
Set your saddle to this height. Measure from the top of the saddle down to the pedal, with the pedal at its lowest point. Fine-tune to comfort.
Handlebar width:—
Order a handlebar of this width.
Stem:—
The short part that connects the handlebar to the frame. Order this length.
Spacers:—
Small rings under the stem that set the handlebar height. Start with this amount.

I have to say, compared to my own old beater bike, this is a completely different ride.
