Something 5Dev shared with me last week that I thought was neat—steel spindles that add around 500g low and central on the bike. They developed them last year with Neko/Frameworks as a clean/simple way to add weight to bikes instead of just slapping a chunk of lead to the bb. Only two options which limits compatibility, but a neat idea nonetheless. Deets - https://www.5dev.com/products/heavy-metal-downhill-spindles?variant=46496811221154
- 139mm = 616g
- 145mm = 649g
- Made from 17-4 stainless steel in San Diego
- $199.99, or $100 up-charge with any 5Dev crankset order
Theres also noise issues within forks. Jordy had an interview, I think with Blister, where they they talked about coil forks and he mentioned that everyone he worked with that tried a coil fork eventually switched back to air and noise was a huge factor.
His take basically boiled down it feels different but it’s not necessarily better.
My hot take on the extra volume added to the RS jobbers is they're doing this to mitigate some of the internal pressure difference between full top and full bottom out. I would not be surprised if at full bottom a Zeb or Boxxer is pulling air past the dust seals up top, causing contamination and of course increasing the pressure in the lowers at top out. At bottom, you have the lowers trying to suck the upper assembly back down and then when it sucks air into the lowers it makes it harder to achieve full bottom out on subsequent deep hits.
Just because we don't think of the lower's air space as a spring doesn't mean it doesn't behave like one.
Also of note, not getting full travel on the coil Totems was also a gripe by some people back in the 26" days. A coil spung unit may not solve the issue at hand.
With this LinearXL talk, I reviewed the patents SRAM has recently filed for their suspension forks, and this is a roundup of what we'll see roll out within the next few months.
1. Linear XL: Reduces casting ramp. This will likely be accompanied by a larger negative spring, which will mean softer off the top but more mid-stroke due do to higher pressures being required. But without crazy end stroke progression on 38mm stanchion forks.
2. Adjustable bottom-out bumper: Rubber bumper similar to a coil shock, adjustable from the bottom of the fork to allow/adjust bottom-out feel. Less reliance on tokens and no casting ramp require new bottom-out feature.
3. Dimples on the stanchions to increase oil coverage and decrease stiction.
Ultimate levels will probably be the only forks receiving the dimples. Bottom-out bumpers may also not be adjustable on non-ultimate forks. Boxxer may not get a new air spring, but Zeb almost certainly will. Lyrik may not get the Linear XL since it's a 35mm stanchion fork. But may see the other upgrades. All forks look to have new chassis design (typical: lighter, stiffer). I'd also believe Rockshox will continue to do whatever they can to keep their bushings as far apart as possible (maybe some tweaks in these new forks), as it's clear this makes forks run smoother.
all you need to know about PVD is that he once put mineral oil in a brake designed for DOT (might've been vice versa) to "see what would actually happen"
Um... You seem a bit confused. At bottom-out the air pressure in the lowers increases and would push air OUT past the wiper seals. If that happened, the air might want to be pulled into the lowers at top-out.
As for pulling air, dust wipers are a double lip seal with a preloaded (spring) lip acting either way of stanchion travel. So even if the lowers tried to push the air past the upper (visible) lip, the inner one acting the other way gets additionally preloaded by the increased internal pressure, making the seal even better.
And it's become WELL known the lowers are acting as a spring on 38 mm forks and causing full travel issues.
What's the opposite of a weight weenie? We should come up with a good name for those that aren't afraid of adding weight to bikes (or themselves
) to improve performance.
"Weight Unbothered."
...but if they bring it up as a badge of honor more than once in a conversation it's called "look-what-I-can-do-ism."
A masshole. Wait, that's taken already.
Ballast Bro?
I really wished they had launched this straight faced on April 1st. It's too bad they aren't European or they may have unironically launched in on April 1st as so many European companies did before them.
Funny how my coil boxxer is as quiet as it can be with simple 2 layers of PTFE heatshrink...Jordi always finds some story to cover the real reasons, guys like Steve from vorsprung find easy solutions to such a small niggles instead (in this case, stanchion liners for 38mm forks), job jobbed.
Imagine you're a average user that doesn't have a workshop, the tools, the knowledge and the heatshrink to pull apart the fork, change the spring, apply heatshrink to it and put it back together. If the fork is knocking, is too soft or too stiff, you need to go to the shop. How much will it cost you to have the correct spring installed? How much to make it quiet if the shop didn't apply the additional heatshrink on their own?
How much does changing pressures on an air fork cost?
In the eyes of the average user, is a coil fork better or worse?
Depends on where you live, so I cannot say how much it will cost you, but I would bet it would cost you less than typical fork service you need to get done with any air spring once or twice a year. With coil spring, you get it right once and you are good to go unless you are on of those guys with +-10kg weight fluctuations. And me personally can do the heatshrink application in about 10minutes, coil change in less than a minute if I have the tools and spring ready. If this much hassle is all it takes to leave performance on the table, by all means stick to air spring. I know I won't go back.
When are Profile cranks going to become hot again?
You sir are correct. Had my wires crossed. Mea culpa!
that new orbea RS e-bike has the new fox float x2 live valve neo equipped
Did they ever become unhot? Contemplating a second set for my DJ right now...
I hate to drag on the way too old coil vs air debate, but there absolutely isn't a difference in maintenance between coil and air.
I've used both for well over a decade now, and it's just simply a myth. Heat shrink in hot Whistler summers and oil/grease bath doesn't last forever, meanwhile I still have one boxxer kicking around with air seals from 2015.
I'm sure there's a thread for this and I have no interest in it, just not a fan of misinformation
Primoz, my guy…
I think you are WAY over exaggerating what it takes to swap coils inside a fork. You can do it in a parking lot with a few tools and a few minutes. Just because it can be done in a sterile laboratory with fancy tools doesn’t mean that’s how it has to be done every time.
Looking at the CNCd frames popping up here and there, whether it's Gamux or others..What's y'all's take on the sharp edges all over these bikes?
I wanna be stoked there's more brands trying out gearboxes, but these bikes just scream "unnecessary injury" to me. It's not always you come to contact with your frame with a lot of energy, but it does happen, whether it's a crash and you get tangled or a slip out of some sorts...I look at a round tube and I look at a machined piece with a few mm radius on the corner, I can't help but wonder why doesn't anyone seem to worry about the frame becoming a bit of a sharp weapon in some situations?
I think if someone isn’t capable of opening a top cap to change a spring, then I am going to assume that that same person isn’t capable of opening a top cap to adjust volume tokens. And then I am going to assume that someone who is not interested enough or capable of swapping tokens, is most likely not even interested in achieving optimal performance from either air or coil. Hard for me to believe that person will even be able to set proper air pressure or service an air spring. So in the end, I think that same person would actually be better off with a coil spring for the simplicity of operation and lack of cost of maintenance. Like Jakub_G is saying, cost of air spring maintenance over time will surely surpass the up front cost of finding the right coil. I have coil on one bike and air on the other. I use both. And both bikes have profile racing cranks 🤘
Good partnership IMO.
Looks to be the whole SRAM range as well. See there's a (assumed) T-Type derailleur on the bike- also with POD shifter.
T-Type launch video with Brendog would be what the soul needs during these grim winter months.
After some serious comparing at work today, I’m inclined to agree, and then the thought occurs to me : KNOLLY is quality, DW is quality, ORION has reviewed really well, when actually used. this bike (assuming it’s a knolly with Orion and two chains) could be a brilliant and durable bad ass woods weapon. ALL THE DROPPER INSERTION. Bet it has 157trail hub width.
Does this mean mavens too? Nothing can compare to the sound of his brakes at champery this year...
Yep, the teaser photo he put on instagram showed maven levers
Mo awesome hiding something from transition. Has a 34sl and the cable insertion is not the same as the current spur
Just drop it please or indeed find the coil vs air thread. No, it is not the case. And if you have an air fork, I have no idea what do you do with it because between all the air forks I've had in a decade, I haven't spent enough on air seals nor grease to purchase a SINGLE coil spring for any fork. (not here to talk about whether I actually use it hard enough or whatever)
Coil isn't innovation, certainly won't make your bike slacker nor longer. Whether it's better or not, this thread should be about innovation, and spewing nonsense about some imaginary costs of "not coil" don't seem to be relevant so maybe bring it to the chainstay thread.
Bringing chainstay to the gunfight I see, not smart my dude lol
