Bacchetta CA-3 Modifications - October 2017

My verbal abilities leave much to be desired (droning) in this video.  But this might be of interest to some.
 
Walk-around video of the numerous modifications made to the recumbent bike. Including: tiller steering, narrow bullhorn bars, Kent Polk Rail Gun carbon fiber seat (modified), disc brake, 650 wheels, headrest.

    Very interesting. Any videos showing you riding? It looks like it would be hard on your wrists.

    No vids of me riding.  But this is a pic of the angle of recline on the CA2.  https://www.facebook.com/EndBrainCancerNow/
    Not hard on my wrists.  But that is a very person-specific issue.

    Dan, I think you will ride faster if your knee tops are below your helmet height . Being so laid back and having your knees up above your head has to be creating undue turbulence around you. That's where a z frame bent like the M5 has an advantage versus a straight stick when laying the seat back so far.

    I agree.  My CA2 is a medium.  The CA3 is a large.  My legs extend further out on the CA3, knees nowhere near as high on the CA2.  (Rich wanted a pic or a vid ... the only pic I have with me on the bike is on the CA2).  
     
    I've looked into the M5 but backed away bc of the right turn problem.  Switchbacks out here are not forgiving.  
     
    I know of a solid bike designer and builder who is doing beta on a Z frame bent that doesn't have the M5 problem.  
     
    Another thing ... with the Kent Polk Railgun seat the angle of recline is much smaller and the seat itself can be pushed back on the seat plate.  Doing so would require a tiller steering system that would extend the shifter/brakes further back ... like I've done.  See the vid posted on this thread.

    Billy Broadfoot dialed in my CA2 (700cc, Zipp 808 upfront and Flo full disc wheel in back) yesterday and I took it out for a spin today. Got a late-ish start but ... lawdy!! That disc wheel slices through the air like a hot knife through butter.

    Ray.  I measured the difference in leg extension between the CA2 and CA3.  Two inches (CA3).  The CA2 is a `medium' sized bike while the CA3 is a `large.'  That, and the fact that I've moved the Railgun seat back on the CA3 one inch further than on the CA2.  
     
    Much lower knee elevation.
