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 ( but John Cobb has posted some generic stuff... also check out

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 ( and If you have any doubts about the tools or you abilities... leave it for your LBS.

As far as handling is concerned, check out for info on fork rake and trail... this might help to predict how your handling may be affected.

Be the bike.
