WS FIT SystemWelcome to the Wrench Science Advanced Fit
For the Advanced Fit you will be taking measurements off your current bike / bikes. We can’t stress enough how important this is for establishing a baseline of how you are currently set up. Even if your current fit is bad there is still great information in these measurements for our fit discussion. Just like a doctor looks at your chart to view your history we are doing the same thing looking at how your bikes are set up and it is just as important.
You will need a tape measure, your bike and a digital camera / smartphone to take photos. Please note that none of the measurements or photos are mandatory but the more info you provide us the better our recommendations will be.
Start by choosing the Bike Type you will be entering and your units of measurement. You can save as many bikes as you want and again the more the better.
Manufacturer
Every brand has it's own personality. Knowing what brands work for you will help us make better recommendations.
Model
Please include the model name as precisely as you can so that we can research it correctly.
Model Year
Models to change slightly from year to year.
(TT) Top Tube or (eTT) Effective Top Tube
The Top Tube / Effective Top Tube is the horizontal distance of the top tube from the center of the headtube to the center of the seattube. To measure start at the center of the headtube where the top tube meets it. Measure from the centerline of the headtube horizontally to the centerline of the seattube / seatpost depending on if the top tube is horizontal or slopping.
Reach
Reach is the horizontal distance forward from the center of the bottom bracket to the top dead center of the headtube. Most manufacturers give this measurement number now and by referencing this will help you ensure you are getting the right size frame.
Stack
Stack is the vertical distance from the center of the bottom bracket to the top dead center of the headtube. Most manufacturers give this measurement number now and by referencing this will help you ensure you are getting the right size frame.
(CC) Seattube CC or (eCC) Effective Seattube CC
The CC / eCC frame measurement is measured from the center of the bottom bracket following the seattube angle to the center of the horizontal / effective horizontal top tube.
(CT) Seattube CT or (eCT) Effective Seattube CT
The CT / eCT frame measurement is measured from the center of the bottom bracket following the seattube angle to the top of the frame seattube or effective seat tube.
(SH) Saddle height
The Saddle height measurement is measured from the center of the bottom bracket following the seattube angle / seatpost to the top of the saddle.
(SO) Standover
The Standover is measured from the center top of the top tube vertically to the ground.
(SB) Saddle Setback
The Saddle Setback is the horizontal distance from the tip of your saddle to the center of your bottom bracket. You can measure this by dropping 4 foot level vertically off the tip of your saddle until it is dead vertical or by using a plumb bob off the tip of your saddle. Then measure from that line to the center of your bottom bracket.
(CP) Cockpit
The Cockpit measurement is measured from the tip of your saddle to the center of your handlebar.
(S) Stem
The Stem length is measured from the center of your handlebar to the center of your fork steerer tube.
(D) Saddle-to-Bar Drop
Road / Cross - The Saddle-to-Bar Drop is the difference in height from the top of your saddle where you measured your saddle height to (for point of reference) to the top of the handlebar to the side of the stem where you hands would sit if you are riding upright. To take this measurement start at your saddle height ending point but now measure vertical to the ground and take note of that measurement. Then measure from the top of your handlebar at the sides of the stem vertical to the ground noting that number. Subtract the handlebar to ground from the saddle to ground number and that is the saddle-to-bar drop.
MTB - The Saddle-to-Bar Drop is the difference in height from the top of your saddle where you measured your saddle height to (for point of reference) to the top center of your grips. To take this measurement start at your saddle height ending point but now measure vertical to the ground and take note of that measurement. Then measure from the top center of your grips vertical to the ground noting that number. Subtract the handlebar to ground measurement from the saddle to ground measurement and that is the saddle-to-bar drop.
(D) Saddle-to-Pad Drop
TT / Triathlon - The Saddle-to-Pad Drop is the difference in height from the top of your saddle where you measured your saddle height to (for point of reference) to the top center of the aerobar elbow pads. To take this measurement start at your saddle height ending point but now measure vertical to the ground and take note of that measurement. Then measure from the top center of your aerobar elbow pads vertical to the ground noting that number. Subtract the aerobar elbow pads to ground from the saddle to ground number and that is the saddle-to-pad drop.
(HB) Handlebar Width
The Handlebar Width is the center-to-center distance of the bars measured at the bottom of the drops. This directly correlates to the width of your shoulders.
