Felt DA1 TT or Tri Custom Build To The Max w/ extras

For sale is this beautiful one of a kind speed machine. Built without a single part overlooked for one goal in focus...to go fast. It is light and super stiff in the bottom bracket which means all energy goes forward. It only takes a few turns of the pedals to grow a smile and gain the apparent feeling that the bike wants to go fast. I am a pro mechanic and owned a custom bike building and mobile bike repair business, I built this bike to be all out with no compromise.

Spec:
Custom polished rear derailleur and crank
Dura-Ace di2 rear derailleur with SLF motion Ceramic oversized pulley wheel system with carbon cage and silver alloy wheels (lighter, lower friction, and looks cool)
Dura-Ace crankset (170mm for more open hip angle allowing slightly more aero position while maintaining comfort and ease of power output)
Custom 54t aero chainring (not as much for top speed but for lowest drag at cruise speed by reducing the tightness of the chains bend around gears)
Zipp Carbon Base bar
Zipp Carbon aero shaped Extensions (uncut so they're as adjustable for fit as they come)
Zipp 808 front wheel with custom chrome graphics (like new and hub serviced recently)
Zipp disc rear wheel with custom chrome graphics (also like new and hub serviced recently. I serviced the wheels not because they needed it but to put lowest friction grease and make them spin as smooth and fast as possible.)
Pinhead aero skewers to save an extra couple watts and look clean and add a chrome accent.
TriRig front brake (custom brake housing routing through stem and bar, expensive, really nice, and most aero option)
I set up the shifting to be 1 di2 shifter on end of left aero extension with 2 buttons. One button shift up and the other down. This one shifter setup allows for a lighter overall build as the brake levers are much lighter without having the extra shifters built in and the extra cables to them.
Aero coach aero chainguide. I never have had the chain drop without the chain guide but I added it for piece of mind and it's super light and aero anyway, chain has never once dropped at all.
I made the bike 1x to be more aero, save a good bit of weight, and because it is still all gears needed as most all TT are pritty flat or if there are rollers you don't need a small ring anyway. If you need a small ring/2x chances are your time would be faster on a road bike.

Also included is a Zipp 808 rear wheel, also like new and I only rode it a couple times.
If desired I can also include a matching white with chrome stripes Kask Bambino size M helmet that I only wore a few times and I basically don't sweat, it's in like new condition and crazy comfortable and high end helmet, only maybe 2 years old mostly sits in its original padded box, also has clear lense and chrome mirror lense.

Bike size measures about 51cm but fits like a 54cm. TT bike fit is a little different. It's a different kind of bike and different position and geometry for that. I ride a 54cm and 56 cm road bikes with 120 and 130 stems. I'm 5'10" and felt the bike fit me perfect. It would fit a good size range, I'd say it'd fit most people 5'8" - 5'11".
