Find your Road Bike Setup like a Pro
Since I added a post on the way to find your tri bike setup, I am now working on my program to help you define your road bike setup. I have two graphics in this post, the first one being an alternative to the one I use in the KGS Bikes studio. The second one is the graphic I use to document setups and it requires a horizontal and vertical line which I create with a crosshair laser.
Define Your Road Bike Setup
The first graphic is usable with a level floor, a vertical line, tape measure and possibly a digital level. You will be well served to use a metric tape measure and use millimeters for your measurements so we can communicate accurately. If you can't use a metric tape, measure to the sixteenth of an inch to get the best accuracy.
Once the bike is stable against the wall and you have your vertical line aligned with the bottom bracket, you can begin.
1) Measure saddle setback from the vertical line to the nose of the saddle
2) Measure from the nose of the saddle back 150 mm and make a mark. You can put a piece of tape there and mark on the tape.
3) This is called the Measurement Point on the saddle. Measure from it (sighting from the side of the saddle to put the end of the tape precisely on that point, down to the axis of the bottom bracket spindle. This gives us saddle height.
4) If you have a digital level, determine the saddle angle.
5) Now the saddle is defined and you can measure against it. Measure from the nose of the saddle horizontally to the point above the centerline of the stem where the handlebars go through. Just look straight down and you can see the place on the tape that corresponds to that horizontal dimension.
6) Then measure from the nose of the saddle to the place on the brake hoods that turns up quickly. I have it shown in the drawing. Just sight with the tape between the two hoods and put your finger on the actual point in the tape that intersects those two brake hood points. Then look carefully and record the number.
7) Measure to the forward inside part of the handlebar crooks just like you did with the hoods.
8 ) Now measure from the stem centerline down to the ground.
9) Finally, measure from the lower crook bend down to the ground.
If you measure your inseam, bare feet shoulder width apart, up to your pubis, record that number as well and we can find your optimal crank length.
This will fully define your setup. It is easy to do but requires attention to detail. If you are careful you can be very accurate in your measurements and I can help you with your position remotely!
