synBike Liked a reply to forum topic Frame design: how to select shock stroke & length?

I wouldn't read much into the Orange comments. They could have done a million things with leverage ratio that gave it a "more planted" feel. That would not have been due to the shock change alone. From past experience in the industry these types of comments often get misinterpreted. Bigger shocks are nicer because they have more oil volume and can handle a bit more heat as a result. Especially in that era where shocks were not as refined this may have been a significant factor. In terms of picking shock stroke it's exactly what previously people alluded to. You...

Obviously, it's hard to say exactly what they were going for with that orange... especially so when you consider the oddities of boost valve etc that was built into the suspension products of the time. Generally, related and along with spring rate, has to do with shaft speeds at the shock and then the resulting oil displacement within the damper. Higher leverage ratios mean higher shaft speeds, which means more oil displaced. There is a delicate balance between the amount of oil being displaced, the compression/rebound piston ports and shim stacks and the base valve shim stacks. Shocks back then...

You digress? I thought we are all supposed to hate digressive valving now!

So the Orange is kind of a unique case - in stock single pivot form they typically had a very flat leverage ratio with little rising rate which meant the initial travel would have had quite a low leverage ratio relatively speaking. The linkage allow for more rising rate so while the average leverage ratio will have been lower, the initial ratio was probably higher. As for choosing shock length - its one of those things that is a sum of several factors - there will be a target rising rate at the wheel, which then needs to be mapped...

Apologies if this has been asked before; Google only returned answers regarding long-stroking for increased travel, which isn't the question that tickled my fancy. On the other site, I read about Ben Cathro's prototype Orange DH bike, where "The link allowed the team to fit a bigger shock and made the bike feel more planted compared to the 224." This...

Another comment that stuck out to me is that multiple people think that the relationship between hardness and temperature is non-linear, with tires performing reasonably well—and then when they drop below 45°F, they turn into rocks.

Well, the other website had a "nerding out" article that definitely felt at least inspired by our conversation here. I understand this isn't exactly a novel topic, but it's still flattering nonetheless. One of the common refrains I saw in the comments multiple times is that "Maxxis rubber hardens a lot in the cold. As does Michelin. While Conti, Schwalbe...

Hey everyone! My name is Ben, I have always loved trail riding with a background in BMX trails, rode those most of my life while skateboarding. Then as I got older I rode less and less trails until about 8 years ago I got my first DJ bike and fell back in love with trial riding. Since then I have went from having my DJ to a hardtail and now to my 2022 Marin Rift Zone 1. I have lots of questions about DH/Full Suspension so I am looking forward to learning more about this beast.

Apologies, I must've misread your comment. Yeah, it'd probably be a long shot whether the total, repeated deformations will raise the tire pressure, but unexpected results do happen.

I should be sleeping right now, but I keep thinking about how automobile/motorcycle racing tires (1) utilize tire warmers before a race and (2) their tires heat up over the course of a race. I tried to google bicycle tire warmers, and it doesn't appear to be a product that exists. Also, I wonder if bike tires can transfer enough...

Unless I'm misunderstanding you, I feel like the math to find the correct pressure shouldn't be additive. What we should be looking for is the delta of internal pressure minus barometric pressure. This makes sense to me because what we want to know is the total pressure pushing outward on a tire so it keeps its shape, and barometric pressure...

Absolutely, I skimmed the copy, but it didn't give up much information. Sometimes, it'll list a specific additive, like orange/citrus/almond oil, but the recipe itself is a very tightly held trade secret.

Here's a good question for the tire nerds: I am not a good test rider. I can't easily tell the difference between 25 and 29 psi, for instance. But even I noticed last month, when I rode a shuttle ride at a high elevation, that my tires were hard. It was cold and the elevation was as much as 7,500 feet higher than where I was when I set my psi. I did not measure at the top; just rode it in hard mode and it got better as I descended. How much does external atmospheric pressure affect the psi...
