First Look: Trust Performance's $2,700 Carbon Fiber Linkage Fork
@ceecee: Top tube length is my most hated geometry parameter. For better or worse, my geometry chart involves a lot of "forcing the issue": seat tube angles are given at the typical "effective" point and at a realistic seat height, reach is measured at the industry-average stack height to facilitate comparison, and our head angle is a conversation unto itself. It's true our frame + fork is more than the Trust fork, but that shouldn't be surprising. A Structure chassis is priced comparably to a traditional carbon frame with a Trust fork, but offers the advantage of clean-sheet integration.

@iduckett: Under the down tube. I'm a water bottle fan, too, so I plan to at least offer a bottle with a flip top to keep the valve clean.

First Look: Trust Performance's $2,700 Carbon Fiber Linkage Fork
@LOLWTF: The most correct answer is "as soon as we finish testing, lock down the final version design, get the factory tooling built, go through the safety/standards certification processes, and optimize the lay-up". The more useful answer is "mid-2019 ... probably". No one is more eager than us to put our bike under the public - as soon as it's ready, you'll hear all about it! Until then, you can ask your favourite shop, trail guide, or skills instructor to contact us about acquiring a demo and you can subscribe to our mailing list via www.structure.bike Thanks for your support!

Great minds think alike! It's about time the linkage concept got the attention it deserves! And now for my complaint: Dave says: "What happens if you build a device that lets the stability of the front-end of a bicycle or motorcycle increase on corner entry rather than decrease? It's a simple question that I don't think anybody has ever asked." Not only have we asked it, this is nearly a copy of the language we use for our Stability on Demand technology. Focus on stability, rather than axle path: yep, that's the core of our technology. Dynamic geometry: yep, that's us, too. Constant trail: in pitch, ditto; in heave, ours increases trail for ultimate stability. Sealed bearings at all pivots with a lifetime warranty: ditto. Proprietary suspension hardware: nope, ours is off-the-shelf. $2700: Perfect, makes Structure look like a bargain! Smile Challenge accepted, Dave. Time for a group test!

Bike Check: The Privateer is Going to Finale on a New Bike
@Chonky13: The first generation parts wereused cast construction. Newer parts are visually identical, but are forged and are twice as strong. So far, we're impressed and I may spec Box shifters and derailleurs on our bikes.

Now THAT Was a Bike: Whyte PRST-1
@cbro7092: Thank you! I hope you get to try one for yourself! You could ask your favourite shop to contact us about acquiring a demo.

Now THAT Was a Bike: Whyte PRST-1
Hi dan23dan23, Although I don't have the CAD files, I've done three simulations with excellent agreement between them. Yes, the PRST did dive, and not only due to brake dive. The braking was well over 100% pro-dive at the start of the stroke (compared to about 30% pro-dive for telescoping forks) and rose to around 100% anti-dive at bottom-out. The second part of the problem was the leverage curve. Most modern bikes are about 10% to 50% progressive, meaning the spring rate becomes increasingly stiff (due to the linkage, not the shock) by that amount as it compresses. The PRST leverage curve was inverted: it became softer by about as much as a highly progressive bike becomes stiffer. No wonder it used every millimeter of its travel on every impact! It certainly was plush, though.

@uncajohn: Interesting design. Have you pursued it any further?

@fecalmaster: I'm afraid that's not covered by our lifetime warranty, but please inquire about our crash replacement policy and we'll set you up with a replacement "unit" as quickly as possible.
