a GT

a red GT

no shit Sherlock, really?

I'm guessing some kind of Zaskar

I thought it was a bicycle frame. Fair enough.

Wharry, what frame is the GT?

Its a Tempest..
Unfortunately I couldn't afford a Zaskar when I was 13.

*easily the SCARIEST WORST IDEA I'VE EVER SEEN.*

Scared me at first. But thinking about it, the direction of the braking force, doesnt have a big enough downward vector to even come close to moving the headset adjuster.

The weakest link (IMHO) would be the bolt. But I cant see thaty experiancing much in the way of shear force. So is very unlikely to fail.

Its a nice, clever piece of bike tinkering in my opinion.

Not true (in my case).
I've been working for a big Japanese bike component manufacturer for 9 years.
Could write a book about scary and bad ideas (and products).
Maybe I should reserve a paragraph or a small chapter for good, successful ideas as well.

I used to read patent applications for a living. Invention can be a scary thing.

please explain.. If you know something I don't know would appreciate your comments. I dont want my girlfriend riding something that Isn't safe.

I have tested it under all my weight with sharp braking.. enough to skid the front wheel, and there is no movement. As i said before there is little shear force acting on the compression bolt as the cap extends into the steerer tube.

... stem cap which is 7/8th inch and extends 8mm, passing through the 5mm mild steel. This allows the shear force to pass directly from the clamp to the cap and into the steerer tube. The bolt is only used for compression and is under minimal/no shear force under braking.
Thanks

please.. let me know your thoughts.
thanks

How many cycles did you do ?
How many samples?
How is production controlled and incoming goods?

dear wharry and all- we had a similar discussion with loads of other ideas in the two threads above.
hope that they;re helpful

nice CX

What a pricky comment. Like I said, I have no intension to sell or produce anymore of these clamps. The kind of H&S testing you are talking about is disproportional. It is a bodge for myself. I tested it myself under no scientific conditions to be confident that if it stops my fat ass under heavy braking it should be fine for my tiny girlfriend. It is being used as a temporary solution on a fixed gear bike and is not the only means of braking.

Cool.. cheers for that.. I hadn't read it before. Some nice ideas there. The original clamp is quite similar to the one I built albeit much more complex. The key being the shoulder which goes into the steerer tube. In retrospect I should have made it integral to the clamp and much longer.. but seems to work fine as it is, as a temporary solution. Thanks

I'd want more reassurance than that, having snapped various 5mm thick steel parts over the years, but I wasn't really critiquing your design, just pointing out one of the reasons why you would be unlikely to enter into commercial production. Many of us make custom parts for our own bikes, which work perfectly well, and if you're anything like me you'll have erred on the side of caution and would find that a rigorous analysis and test program would prove your effort to be over built rather than under. There is a huge leap, though, from home bodging to charging people money for a product.

He knows that you complete penis!

Fucking know-it-alls get right on my tits, whether informed or uniformed. That includes you Ed.

Wasn't even intended as advice for you, anybody with the wherewithal to design and build a hack like that doesn't need telling. I was really addressing the crowd, telling them not to hold their collective breaths waiting for your personal project to become a product.

Ok, fair enough.

I'm getting a bit obsessed with taking photos of my bike... but this is the final set-up.

Black seatpost, silver saddle?

Black seatpost, silver saddle?

The saddle is actually black, and the seatpost silver... is that hard to see in the picture?

@Wharry
When I saw your clamp last night, I immediately thought of that one above, I imagined
that a good solution would be to have a clamp that would fix such as a stem with a metal wedge would.
Or a nut expander, being that the only problem to deal with would be clearance of the tire.
That example (A), seems to correct that, very nice. Again, I'd have a go at that.

It was a suggestion, dumbo

No shit, Sherlock.

You beetter be going to the pub

Get me a Campagnolo NR in Black 26.2, or any Campagnolo 26.2 in black, and I'll get the Flite covered in
Silver. Didn't think so..
