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

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.

Getest door het tijdschrift Fillari in de gravelbike-vergelijking van 2026: de "Halo CX GRX 800 Di2 maakte indruk met een ontspannen rijgevoel en kwaliteitsonderdelen."
Ik moet zeggen dat dit, vergeleken met mijn eigen oude fiets, een totaal andere rijervaring is.
