Precision Assured, Upgrades Available
- After considerable searching and testing we were pleased to find an inclinometer in a small form factor that could allow us to keep the retail price under $100, while providing consistent accuracy.
- Prior to shipment, each inclinometer is tested at 0 and 90 deg. against our SPI Pro360 master inclinometer to ensure there is no more than 0.1 degree variation to the master.
- A PRO upgrade kit is available for existing Dupli-Fit owners for $30. Use the Contact Us link for more details.
- Satisfaction Guaranteed: If you’re not completely satisfied, return Rotor Protect 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Outdated approaches remain until better ones are developed and widely available.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.
