That is what it takes to go 80mph. Decades of experience(which Obree had in time trialing), and/or tons of engineering. Neither of which he has in the extreme world of streamliners.


"and/or tons of engineering" this statement ignores the very important role of the VU Amsterdam Kinesiology department http://hptdelft.nl/en/index.php?option=com_content&view=category&layout=blog&id=36&Itemid=195. Selection and support and training of the riders has been a very important factor in realising last years fastest run Battle Mountain.


Obree wil have succeeded in my eyes if he shows up at BM and gets a couple of runs in. In doing so he wil have completed the yourney. If he goes over 70 mph I wil be amazed. Anything beyond that would be sensational (however highly unlikely).

I wish Obree well with the yourney! Go Go Obree! One of the reasons I am interested in high speed cycling is Obree.

Yes, sorry for neglecting the physical element. Would Mr Obree have qualified to ride for Delft? I didn't, and with no impressive results for a long time, I doubt he would either. I have nothing against Obree, he was a great champion and inovator 20 years ago. What mystifies me is why people give him credit for abilities for which he shows no proof. Decades ago he built his record setting bike, which was likely more due to his revolutionary riding position and champion level ability. What bikes has he built since? And as he has stated he isn't accepting help, what experience does he have in lofting and building a shell? As I know better than most, just making it to BM is an achievement, let alone qualifying. But increasing people of every age, sex, home county, and financial situation do it. And with much less fanfare. And without overselling themselves. Maybe Boardman will decide to do BM. Now, with his continued involvement in cycling, composite bike construction, and aerodynamics, that would likely produce results.

Maybe something like this:



Just my own interpretation of how Obree's fairing could look like based on his side picture, 406 wheels and a possible lineal / elliptical drivetrain.
What do you guys think?

That's a pretty sweet "interpretation", Juanjo. It will be interesting to see how close this is to Obree's actual fairing.

If Obree teams up with Juanjo I change my prediction.

Jaunjo
nicely done modeling
clearance around the pedals is to tight
some allowance to be made considering your work was done from a single photo
again
nicely done

If Graeme shows it would be cool if IHPVA welcomed him with an 'illegal vehicle plaque' for old times sake to keep his streak and spoof the UCI.

Including training wheels and a hacksaw to cut the nose off the seat to make it legal.

Juanjo, can I have your permission to include the photo on webpage that shows each rider and his vehicle for Battle Mountain? I would label it as your Artist's Interpretation of course!

Mike, of course you can! Below there is also another detailed picture of this fairing compared to a Varna Diablo III and the VeloX:



Glad to see you guys approve my design, thank you!

Juanjo, can you enlarge the foot flail envelope to allow for the movement of the feet?

Thom, I designed a small pedal box considering the use of an ultra narrow K-Drive, with a 60mm q-factor and a feet width of 100mm each one. Ultra narrow K-Drives are difficul to design and build durable, but not impossible...

Anyway, tomorrow I'll try to redisign the rear part of the fairing to allow the use of "normal" 170s cranks combined with a possible drivetrain.

Very nice. While none of us have heard of you, I am sure many are hoping you will build a real streamliner.

With Obree's head first position the actual fairing shape can be more teardrop shaped than the illustration above. What will Obree cook up in his kitchen? Time will tell.

That design looks taller than the 32 inches quoted in the article. I think that is an "artists concept" by a less talented artist than Juanjo.

Maybe it's a tandem.

IIRC, there was a "tandem" at one of the early-'80's IHPSC's that featured 2 prone riders, one on top of the other. Frightening-looking, and inspired more than a few dirty jokes.

Something doesn't add up. That picture looks to be "artistic" and purposefully absurd. Makes it seem like Wired is trying to make Mr. Obree look ridiculous. That is unfortunate.
