Measure Smarter, Not Harder.
Dupli-Fit directly and accurately locates the handlebar and bottom bracket (center of pedal rotation) relative to the saddle. Simply measuring saddle height does not uniquely define the relationship between the saddle and the pedals or bottom bracket. Also, distances cannot be measured accurately if the endpoints are not positively located and the scale is not accurately read. Holding a tape measure between two points fails on all counts. Dupli-Fit provides a positive location to the bottom bracket center and a separate scale for determining the handlebar centerline.
Equally important is that the right reference point is used, and that is it located accurately and repeatably. Dupli-Fit does this with an integral gage for locating the widely accepted saddle reference: 80 mm width.
Elegant design, accuracy and speed are not mutually exclusive!
Get faster and more accurate results—every time.
The Dupli-Fit Advantage
- Ease of Use: Accurately capture the saddle-handlebar-bottom bracket relationship on any bike in less than two minutes. Just as valuable, avoid the time-consuming trial and error in trying to set up a new or rental bike to known values
- Unparalleled Accuracy and Value: Each unit is individually calibrated on a master jig. Professional-grade accuracy with a price that fits your budget
- Convenient and Durable: Small and compact enough for use anywhere, anytime. Constructed of durable SLS printed Nylon 12, fiberglass and an industrial-grade coated scale, Dupli-Fit weighs less than 6 oz (170 gr) and fits easily into a standard carry-on bag and hangs on your garage or shop wall
- Satisfaction Guaranteed: If you’re not completely satisfied, return Dupli-Fit in as-received condition within 30 days for a full refund of the purchase price
User Reviews
Really enjoying your clever tool. Becoming super quick way to check, reposition. Great work!

Used Dupli-Fit on my road and gravel bikes that I thought I’d setup identically but they were off. This tool is more accurate and faster as well. Thanks.

FAQS
If length & angle is so much better than X, Y why isn’t it widely used?
Outdated approaches remain until better ones are developed and widely available. Bike setup/fit tools are not sold in large numbers so innovation comes more slowly.
But does that mean length and angle are any better?
Yes, because if we are comparing Dupli-Fit to even the most careful use of levels and tapes/meter-sticks and basic jigs, we are reducing the number of individual steps and the potential error involved with each step, which are largely due to lack of registration and parallax error.
Why not do a better job with X, Y instead of inventing a different approach?
Because X, Y is fundamentally flawed. It became the standard when levels and meter sticks were what was available. Don’t we describe a bike’s handling characteristics in terms of length and angle? More directly, fitters work in length and angle. A goniometer uses exactly the same principles. Shouldn’t we use the same language for the bike as we do the body?
If my fit data is X, Y how can I “Dupli” my fit in length and angle?
You’d have to go to an online calculator to convert, but we saved you the time and went one better by providing both tabular and graphic representation of up to five bikes in an Excel-based app available as a free download on the site.
