AgrAde Added a reply to Modern Geo Talk: Chainstays, Stack, Reach, and Bitching About It
8/1/2025 4:57am Yeah if you have adjustable chainstays then you're basically adjusting the length of the lever that actuates the shock, so lengthening your chainstays will slightly decrease your spring (and damper) rate at the wheel, while correspondingly giving you slightly more travel. It's pointless to consider the actual length of the lever, because it doesn't physically exist, nor is it possible...

7/31/2025 2:24am 1) I think you're at the exact peak of the Dunning Kruger graph here. 2) That was a hint to get this discussion out of this thread.

7/31/2025 2:19am Oh ok you're one of those. Cool. Please define what you consider a "chainstay" succinctly in a way that actually covers all suspension layouts. I understand suspension dynamics and the concept of leverage quite well. The final year of my degree was mostly concerned with mountain bike suspension design and a fair amount of my experience in engineering has involved...

7/31/2025 12:48am Posted by noideamtber: [quote] chainstay length itself is also the distance between rear axle and pivot point - this is why the actual length matters so much, that pivot could be infront of the BB or behind it. which has quite a role in anti squat, leverage of the stay etc - it also directly relates to where the BB...

7/31/2025 12:49am Every time you mention this random ass definition of what a chainstay length is, i can't help but think about how it doesn't make any sense unless you're talking only about single pivot bikes, and how everyone you talk to is going to misunderstand you anyway. The fun thing about language is that words mean what people understand them to...

7/30/2025 5:20am You're talking about the horizontal distance between the bb and axle. That does shorten after sag. The axle still moves upwards, away from the bb, extending the distance between the two. Which is what Primoz seemed to be talking about.

7/30/2025 1:27am Yeti chainstays don't shorten through the stroke. Their wheel path is basically the same as anything else non high pivot within a few mm. The SB160's chainstays go from about 440mm centre to centre at the top of travel to about 465mm at bottom out, with sag at about 448mm, for instance.

7/29/2025 8:50pm With consistently high AS/kickback rate, consistently high AR, in practice Switch Infinity bikes just ride like linkage driven single pivots. They tune their AS to drop right at the end of the stroke to minimise kickback, but if your suspension is compressing fast enough to give you kickback while it's already 95% compression then you're about to have a bad...

7/25/2025 11:03pm Yeah you absolutely need that front length for that style of guard. I cut the front of the guard off my moto at one point because I fucked it in a fence and didn't want to have nothing until the new one turned up. Had about 5-6 inches of length in front of the fork and it was absolutely terrible.

7/25/2025 2:58am I've replaced my Status 160 with a 2023 Norco Optic. It is getting the EX511 mullet wheelset from the Status and a 140mm lyrik, I'm going to raise the rear slightly with an offset bush. It's going to be used for what you'd normally use an enduro bike for i guess, it's going to be my tail-happy play bike that...

7/19/2025 11:26pm I call it aluminium too but I don't feel like I need to "correct" people about it. It started out as Alumium but then was later named Aluminum by the guy that first worked on isolating the element, and the name was based on "Alumina" which had been in use for a long time to describe the naturally occuring aluminium...

7/18/2025 10:22am North America is weird in a different way, in that those are cringey forced jokes. Steezl is by far the worst. King of the hill is extremely well known here, on the opposite side of the planet. Top tier entertainment and those stickers are the best

7/18/2025 1:46am Weird euro stuff. It would have been like "we want the word pro because pro is about peak performance... propane is a fuel with high energy density and explosive power, can we use that word? What if we change pane to pain? like embracing the pain of a good workout or a really hard effort...?" Meanwhile, English speakers: "PROPAIN AND...

7/16/2025 11:28pm Yeah that's brake setup 101 IMO, people who run their brakes half a mile away from their bars are cooked.

7/16/2025 2:36am Code RSs still uses bushes for the lever pivot and they always just wear and feel crap very quickly. I have no problem with bushes in Shimano levers but SRAM ones just don't last well. Code RSCs are on another planet in terms of longevity/performance just because of that IMO. I have a "BMX background" (lol) and often don't even...

7/13/2025 11:51pm I've run a boost hub in a non boost frame by just jamming it in there and buying a new thru axle. It worked great until the chainstay cracked. It worked long enough that I got what I wanted from the frame and then some, so no regrets, but i absolutely wouldn't recommend it. I think it lasted about a...

Only mad dogs and Englishmen would tear apart a perfectly good rear wheel to re-use only the rim.

Changing the wheel doesn't change the wheelbase.
