I have a Calfee sizer, and using the stack and reach evaluations for any body that is looking for a new bike.
I have some difficulties, to determine the STACK ,
The problem is I don’t have any reference where the head tube finish.
I know where the head tube start, ( bottom of the head tube) and I position the SALSA stem flash to the head set on top,
I reduce the height of a regular stem plus 5cm for the spacers , and that, theoretically should give me the size of the head tube.
But is no right the measurements are completely wrong.
Any ideas ?
Or somebody that has the Calfee sizer.
thanks

Hi Marcelo,
Give us a call for help on that. Talk to me or Mike. 800 965 2171.

Put a 15mm top cap on “steerer,” under the fit stem, and pull stack/reach from that. The bottom of the headtube isn’t used in stack/reach calcs, so you can just pull that measurement at the top of the frame, where the slider/steerer inserts.
I can post pics of how I zin the calfee sizer, if that helps.
Hello , has been a while since I post that question I kind figure some ways how to get the stack and reach .
But I always open to better ways ,
I appreciate your help.

We just started offering a slightly modified Purely Custom XY tool that fits the Sizer perfectly: http://www.purelycustom.com/p-290-xy-tool.aspx We’ll have it listed on our website soon. Price will be slightly higher than Purely Custom’s to cover the modification.
Speaking of pricing, I notice that we have probably the best value in a Sizing Cycle. $3,200 gets you quite a few more features and easier/faster adjustments than fitting machines that cost thousands more. Made in California. Check them out here: http://www.calfeedesign.com/product/sizer-cycle/
