Who ever did this, he is the kind of person who make things happen in this world. Keep on creating and improving. Garage designers/inventors are really not worried about aesthetics in the first iterations.

my first thought was, "how much does it weight?" i mean everything except for RD, cranks, and pedals are all custom and probably made by himself.

i wish he put drops on his bars

i almost want to cry here, those spokes look taped on:

and the saddle and seat post are integrated and don't even need a seat collar


i bet this guy doesn't need to worry about the bike getting stolen. he can just make another. also how can you tell the cassette is hand made?

spry

Wonder how many weight weenie "dufus speil" folks here are placing their online orders?

rooftest

Looks almost professional compared to that frame. Is that bondo that he used to attach the rear dropout?

I really want to know what's going on with that rear brake...

m4ximusprim3

the more I look at this, the more impressive it is. besides the frame and bars, those are homemade carbon aero wheels.

It may not be the prettiest, but this guy is at a level of experimentation I can only dream about.

Flatballer

Is that an 8 speed rear derailleur? I'm guessing he removed the springs from both DR to make it much easier on the servos.

Very cool, and definitely a lot of work. I like it.

Also, integrated seatmast/saddle, it'll be the next thing.

operator

Next thing?

That's already available on production bikes.

Flatballer

You misunderstood. Obviously seatmast is already a thing (I ride one). I meant saddle integrated into the mast as one piece (like on the bike shown). I haven't seen that yet.

woodduck

^^ which bike can you buy with a saddle bonded to the seatpost?

the wheels look like campagnolo euros with a fairing attached, patches to cover the spoke hole.

rangerdavid

very nice work. its always good to try to do stuff yourself.

oh, and pcad, i believe that's "overclocked" processors.

Fart shifting......waaaayyyyyyy more advanced than the current Di2 grouppo.......

Patriot

Until the gear shifting operates by brain waves, any electronic shifting is useless imo.

Weight weenies have been doing one piece saddle/posts for a while...

Flatballer

can I buy it? I haven't seen one sold. Obviously someone has made one (it's in this very thread).

umd

I believe ax lightness, m2, schmolke (sp?), etc all make saddles integrated with seatposts.

Flatballer

I see. But those aren't masts. I really doubt anyone will ever make an integrated saddle on a seatmast (at least not for production, maybe for some un-rideable weight weenie thing).

This is how Lightweight wheels got started: Two grumpy olde farts in their garage with some carbon and resin.

They ended up ok.



True story.

This really isn't too hard to build. Anyone who can program PICs, a developer board, some high speed/torque servos, you can build this system. The programming wouldn't be so hard either, its just getting the spacing correct. It would be simple to program in auto trims, auto over/under shifts, on the fly adjustments.

Nickel's worth of free advice: stick to commenting on bike schwag.

Flatballer

I wouldn't call that "isn't too hard to build". Just because some people with bachelor's of electrical engineering degrees have the skills to build one, doesn't make it easy.

Hell, I'm an EE senior and I couldn't build this without a lot of reading and time and effort.

sonik90

to me it looks like it is going to crack apart/short circuit and find a place in the junkyard.

unterhausen

Just trying to figure out if the people asking questions like this realize that a significant portion of any carbon bike is epoxy. In particular, the dropouts on almost every carbon bike are bonded in with epoxy. JB Weld and bondo both look a lot like epoxy. On production carbon frames, they spend a lot of time smoothing everything out, much like car repair guys do with bondo.

If your first response is "it's not pretty," you lack imagination. Whoever built the frame could definitely go pro, it's far from a hack job.

this is the best thing i've seen on BF for the 2 months i've been on here

JakcBeNimble

So.....how well does it work? Its awesome in any event, and I'd love to see more details.
