Y Foil fork blues(2 posts)

Y Foil fork bluesnate

I have just purchesed a Y Foil for TT's. Does anyone know if any windtunel tests have been performed for aerodynamics? Also I would like to change the fork because the blades on the stock bike are too long. Has anyone changed a fork on one of these, how did it change the handling?

... There have been some impromptu independent tests done on the Y Foil, but I can't find the link (time in a windtunnel is expensive for an independent test (http://www.bicyclesports.com/) but John Cobb has posted some generic stuff... also check out http://www.slowtwitch.com/

My memory says that the Y Foil was not particularily aero, but that shouldn't dissuade you from racing on one (locally, many do). While lowering your bike's aero drag is generally a positive thing, the rider is the most unaero component of the package... and tuning your own aero position and form would probably make up for a small amount of frame drag.

I'm unclear of what you mean by "the blades on the stock bike are too long"... Swapping out a fork is a relatively easy proceedure if you've got the right tools and attitude (http://www.slowtwitch.com/mainheadings/techctr/maintenance/maintenance.html and http://www.parktool.com/workshop/FAQindex.htm#headset) If you have any doubts about the tools or you abilities... leave it for your LBS.

As far as handling is concerned, check out http://www.anvilbikes.com/tech/Feb-27-2000-2134.shtml for info on fork rake and trail... this might help to predict how your handling may be affected.

Be the bike.
