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);
an 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 and more stable front end is easier to hold in the aero position.
The saddle often moves slightly forward and up in aero use.
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.

Probada por la revista Fillari-lehti en su comparativa de bicis gravel de 2026, la "Halo CX GRX 800 Di2 impresionó con su sensación de marcha relajada y componentes de calidad."
Tengo que decir que, comparada con mi vieja bici de batalla, esto es una forma de rodar completamente distinta.
— AamulehtiTomi Pyy, periodista, Aamulehti, primeras impresiones de marcha, julio de 2026
Spektri C° Shimano 105 Di2 Carbon builds on the Spektri C° platform for endurance and all-road riding, with a more relaxed riding position for long distances. Its endurance geometry provides a more upright, relaxed position for long rides, rough roads and light gravel.
The Carbon build adds Valois HBRD 45 carbon wheels with an HG freehub and a Valois Vael 145 mm saddle while retaining the base model’s Shimano 105 Di2 drivetrain and alloy Valois Aˣ cockpit. Electronic shifting and hydraulic disc brakes form a practical specification for regular training and longer rides.
Each bike is assembled by hand in Tampere and individually inspected before delivery.
Spektri C° Shimano 105 Di2 Carbon is built for endurance and all-road riding, with a more relaxed riding position for long distances. The endurance-focused carbon frame keeps the riding position more relaxed for long days and varied surfaces.
Spektri C° combines a carbon frame with balanced endurance geometry and tyre clearance up to 45 mm, subject to actual tyre and rim dimensions. The frame uses a UDH derailleur hanger and a threaded bottom bracket. Each bike is assembled by hand in Tampere, Finland.
Built with a Spektri C° carbon frameset, Shimano 105 Di2 2×12 drivetrain, Valois HBRD 45 carbon wheels with an HG freehub, Continental Grand Prix TR 32 mm tyres, Valois Vael 145 mm saddle, and Valois Aˣ HBRD alloy handlebar with Valois Aˣ Unis stem.
