2-Frame TT Stem & Handlebar Comparator v.1.0 (162KB)

Choose the
Frame TT Stem & Handlebar Comparator when you want to compare different stem, handlebar, spacer combinations on 2 bikes in your possession (effective TT measurements, effective seat tube measurements and top tube to top of headtube measurements c/c are required).

Will be changed to include Road Bike Handlebar, Quill Stem, Saddle and Seatpost processing soon.
3-Bike  C o m p a r a t o r  v.1.7 (1168KB)
Choose the Bike Comparator when you want a theoretical tool to evaluate different frame, fork, tire, stem,  handlebar, spacer, saddle, seatpost and crankarm combinations.  Manufacturer specifications are required for all input variables.  Program outputs corrected values for headtube angle, wheelbase, bottom bracket drop, bottom bracket height, seat tube angle, effective chainstay, whenever the geometry is changed while providing effective seat tube length, actual top tube length, effective top tube length and crankarm ground clearance.  For wheel sizes 16", 20", 24", 26" MTB , 650C and 700C Road , 29er, and for Clamp  and Quill Stems. Provides correct geometry with fork changes and front or rear wheel changes. Fork and Wheel Table Sheets are user updatable.  Displays rear tire to seat tube clearance distance and front tire at full fork compression to bottom tube clearance distance  in number and graphic form.  Allows a number of reference point views to compare bikes (v.1.1 had a BB reference point only).  Visually compare bikes relative to the Bottom Bracket, Rear Axle, Front Axle, Rear Tire, Front Tire, Headset, Handlebars, Saddle, Ground Level Rear Axle,  Ground Level Bottom Bracket, Ground Level Front Axle, Ground Level Headset, Ground Level Handlebar, Ground Level Rear Tire, Ground Level Front Tire, Ground Level Saddle using the reference point code. The reference points do not have any bearing on component and geometry calculations, they are only useful for visually comparing  bikes at different reference points. 
(Wheel changes, fork changes, road to 26" MTB bike comparison, 26" to 29er  bike comparison, road to 29er bike comparison examples are provided at
this site, but presently with an older version of this program.)
4-Shared Mail Order  v.1.2 (1014KB)
Choose Shared Mail Order when you wish to make mail order purchases (at home or from abroad) and want to share expenses with a number of other individuals (12 max).  Allows up to 100 items per person.  Calculates taxes and customs and shares shipping amongst the participants pro rata. Allows the user to specify any currency for the country of purchase and the home country,  using a currency conversion factor (credit card rate) and currency identifiers. Once the individual's items are entered, all the items are copied to the summary page for error checking. Once the summary and individual lists are 100% corresponding, the user can call the store and order the items listed in the summary.
