The Sizer Cycle
After years of development and refining, the Sizer is now available! Designed by Bernie Mikkelsen, this sizing cycle is made for ease of use and ease of understanding by the person being fitted. The technician can quickly and easily adjust all the important dimensions with quick releases and a hand crank top tube extender. The top tube extender is especially handy for the rider to feel the effect of a longer or shorter top tube while the technician turns the crank handle.
You can duplicate the geometry of any manufacturer's production frame directly from their published geometry charts. This allows the rider to test ride a demo bike that may not fit perfectly just to get an idea of the ride quality. Then they can check the fit of the correct size frame and get the right stem length and saddle position on the first try. This makes special ordering frames easy and risk-free.
You can also use it to simulate different possible stem lengths on a bike in stock. . .and change the actual stem only once on the stock bike.
* Quick and accurate custom fittings
* Easy to use by almost anyone in the shop
* More added value for production bike sales
* Roll a bike up next to the sizer and compare it directly to proposed changes
* Add a power measuring device and conduct performance optimization studies
* Communicate measurements quickly and accurately to the custom framebuilder
Adjustments that can be made directly:
>Seat tube angle (from 71 to 79 degrees)
>Seat tube length (from 43 through 72 cm)>Top tube length (from 46 through 70 cm)
>Head tube angle (70 through 75.5 degrees)
