You trained for months to get to this race. The day before, you pick up the rental bike and it feels like someone else’s: saddle too high, handlebar too far, a strange pedal stroke. You can avoid that. And it all starts at home, with a tape measure and a sheet.
The rental bike doesn’t have to be yours.
It has to be in your position.
Pack your position in your bag

A few millimeters at the saddle or the handlebar change how you ride. They change where your weight rests, how your knee works and how much your legs, back and hands can take after hours on the bike. On race day, what looked like a detail becomes discomfort. And discomfort becomes lost pace.
The good news: your position already works. It just needs to be written down and packed in your bag.
Before you travel: measure your bike
There are six measurements. Take them with the bike upright, on a flat floor, with both wheel axles at the same height and nobody sitting on it. Mark the points and photograph each one.
| Measurement | How to measure |
|---|---|
| A · Saddle height | From the center of the bottom bracket (the axle the cranks spin on) to the top of the saddle, in a straight line along the seat post. Mark the point on the saddle and take a photo. |
| B · Saddle setback | Horizontal distance between the saddle tip and the vertical line through the bottom bracket axle. Use a string with a weight. |
| C · Saddle to handlebar | From the saddle tip to the center of the handlebar at the stem, measured horizontally. Don’t measure diagonally. |
| D · Saddle / handlebar drop | Height of the top of the saddle above the floor minus height of the handlebar center above the floor. Positive = handlebar lower. |
| E · Saddle angle | In degrees: a ruler on the saddle and your phone’s inclinometer. Nose down = negative; nose up = positive. |
| F · Crank length | The number is stamped on the inside of the crank arm (170, 172.5 mm...). Or measure from axle center to pedal axle center. |
Also write down the saddle and pedal models, the stem length and the handlebar width (center to center, on the drops).

Bring what’s yours
Your shoes and pedals, always. If the shop allows it and the mount is compatible, bring your own saddle too: it’s the contact point that weighs the most on comfort.
An honest warning: different saddles change the tip reference. Copying B and C doesn’t guarantee the same body position. That’s why the photos matter so much. Take the whole bike from the side, the marked point on the saddle, the ruler and inclinometer on the saddle, your hand positions on the hoods and the number stamped on the crank. Then repeat the same photos, from the same angle, on the rental bike and compare them side by side.
At the shop: order matters
Don’t leave it for the day before. Adjust calmly, not with the pickup line behind you, and in this order:
- Pedals and cleats: check the crank (F) and the cleat position.
- Saddle height: set A to your bike’s value.
- Setback and angle: set B and E before touching the handlebar.
- Reach to the handlebar: fix C with the stem.
- Drop: set D with spacers or the stem.
- Tightening: ask for the correct torque values and write them down.
Don’t move the saddle forward to make up for a longer bike. The saddle sets your relationship with the pedal. Reach is fixed at the stem.
The short ride
Before the long workout, ride for a few minutes. If something bothers you at 10 minutes, it will scream at 90. Go back, adjust and test again. It’s better to lose half an hour now than to suffer through the whole race.
One caveat: the sheet helps you reproduce a position that already works for you. It does not replace a bike fit.
