Lowered the shoulder/neck support for better breathing and aerodynamics. Reduced the track three inches. Shortened the steering linkage arms and tucked the steering linkage behind the frame crossmember. Cut off derailleur post. To do: fair mainframe into crossmember and seat. Add trailing edges to crossmember, enclosing steering linkage. Break BritC's Putah Creek TT trike record. Figure out how to beat his overall recumbent record too.

New crossmenber

Next step: hide that steering linkage behind the crossmember and remove the derailleur post.

Crossbar modification

I added an alternate crossbar and will cut off the original. The original was fully exposed under the bike and the new one will be attached above the main tube instead of below and tucked into the window of my body. It should be a significant reduction in frontal area.

I ditched the stock seat and replaced it with the one I had on my dual-20 lowracer and bonded it to the frame. I did the same with the upper back/neck support. This much improved the handling as the stock seat flexed quite a bit laterally. It also allowed me to be more laidback. In the interest of simplicity and cleaning up the rear end aerodynamically I beefed up the upper stays and cut off the lower ones. I also reinforced the main tube to compensate for the loss of torsional stability. It's a rock now.

Eventually I want to shorten the steering linkage arms so that the linkage is tucked behind the frame cross-member. Once that is done the plan is to add a trailing edge to the cross-member. I've toyed with the idea of reducing the track a couple of inches but I might be making more trouble for myself than it's worth.

I hoping to do my first TT at Putah Creek in March (if they start that early).
