@@jonfrance7201 You're welcome! Let me know if you need help with anything else!

@@ColtonVr127 you'll need to take the tire off and inspect what's going on.. Could need a new tube or new valve assembly if you are running tubeless.

@@TheMarkList thank you !

@@ColtonVr127 any time!

@@dagunshopsaretheworst you are very welcome! Glad I could help!

@@MTB_FANATIC99 hah! Right?

'i love my 50mm rise Enve DH bars... i think a more upright position suits descending and downhill the best!

@@sarcasticguy5823 good to hear!

Sounds like you may have a bad valve core or a faulty tube. I'd take it to your local bike shop and have someone look at it. Hard to diagnose without seeing it myself.

Some air pump has a manual lock

@@MatthewFolan-g2r I have the heavier version. I ride my Enduro like a dh bike... I'm 6"2 190 and ride hard... I'd get the heavier version first. If I remember correctly the heavier one is more effective on larger square edged hits etc... The rougher the terrain the better it works!

I probably have 6 stems.... So I feel ya!

@@CecilBriceno you're welcome!

@@alex1231235 Smith! I have 2 different models like that. You're gonna want the Shift XL Mag... They're my go to on the road bike!

@ Ok thanks! Btw what do you think of 100%?

@@anthonynazzal1958 they're making one for the seat tube also.. Apparently that's what Lori's vergier ran.. Or he ran 2 of them. I know one was by the bottom of the seat tube

@@anthonynazzal1958 I did an interview with him I'll be posting soon.

@@ClawHammer23 any time!

i had a k2 snowboard back in the day with pezio electronic dampeners that converted vibrations into electric current. the board had little lights that would light up when riding. So many applications and possibilities. this damper had some of the most visible and noticeable ride quality differences than any product i've used. it's pretty wild. I'm going to be putting another one on the rear part of the front triangle.

@@TheMarkList That's so cool! BTW, According to ChatGPT, Electric mountain bikes and high-performance road bikes are exploring active suspension systems, where piezoelectric materials could adapt to trail or road conditions in real-time. Couldn't find much actually being done other than Fox patenting a mass damper. I can imagine something Piezoelectric going into the rims since that's probably where the majority of the nasty harmonics are generated. Maybe within the shock's systems as well but I would expect this is fairly well dampened already. Bars are another good candidate. Well, time to look into it and see what can be done. We don't need anyone's permission to try this out, do we!?

what amazes me is how skeptical people are and dont try new things... these were used by the fastest riders in the world racing downhill.... enough said..!!

@@TheMarkList What if you do some videos on Fox's Live Valve Neo and/or RockShox, with their Flight Attendant systems? These are a step in the right direction. These are fairly recent emergent technologies.

@@probalint just tighten till snug. Don't over torque it. Usually 12 to 15nm

@@_burd yeah it actually keeps the bike on the ground more... Ill have the inventors interview up soon!

rimpact is making one that you put inside the steerer tube. The way TMDs are implemented is that they are tuned for frequencies that are outside the envelope of normal dampers i.e. 10-25hz which includes frame pings, brake bumps, super fast square edges and undamped tire "jounce"(tire jounce is more of a problem for motorcycles and these are considered as mandatory safety device in some motogp competition). pedal bob is too slow for TMDs to cancel out of phase.

@@SneakyB I've seen the rimpact one and it's kind of small I imagine it's not heavy enough for bigger hits and downhill or descending super rough and Technical Terrain. These don't work on smooth flowy runs they're really just meant for super hard edges hard hits and the harder the hits the more effective the damper is. The one I'm testing is approx 525grams and the affects are amazing. Was testing on a double black diamond run at Mammoth Mountain Bike Park called Follow Me., I'm going to be adding a second one to my seat tube just inside the rear triangle for more benefits to the rear etc.

@@TheMarkList it's not necessarily the size of the suspended weight but it's the density of the material, where in rimpact's case they're using tungsten which is 19g/cm3 vs steel which is 8g/cm3. hopefully you can persuade countershox to make a mount for the seat tube. maybe even integrate as a seat collar would be really nice.

@@SneakyB true, but being able to easily add or remove the device is key. Also, this has been tested and used at uci dh world cup level. they are making a 3d printed mount for the down tube. You want it inside the rear triangle so the back wheel doesn't hit it. also, how pricey is tungsten versus other materials? I would imagine you'd want this to be easily mounted anywhere on the frame. Like trek did with Loris Vergier. You should get one. They offer a money back guarantee.

@@BradFlanagan-tn8ky no, just by hand

@@sladeoriginal they aren't related but it does affect where your weight goes.. Just like your head tube angle etc

maybe 4 seconds if you use a stopwatch :)

@@davidlloyd1389 glad it helped. They can be a pain in the ass.. Especially when they slowly leak!

@@ken46120 almost all of these trails are on Trail forks. And you can download the files to a Garmin bike computer and then use the map function to navigate to the trails etc.

@ I guess I need some garmin type of thing then.

@@darrinkulyk9560 he's got a money back guarantee too.. I'll be testing one attached to the seat tube for the middle/rear of the front triangle.

@@mokotrampalso depends on the type of riding you do.. That's very common on an XC set up

@@TheMarkList 50mm feels great for fast single track! My slack HT hooligan rig is now on bikepacking duties, 50mm is horrendous, 100mm is the sweet spot!

@mokotramp yeah it's so depends on the person, their build, the bike, the terrain, type of riding etc. My focus was on Enduro and dh duties...downhill in super techy terrain

@@kylew6275 they should absolutely be rideable. I'm in Mammoth still riding and haven't ridden down there yet.

@ awesome, looking forward to checking them out. This vid was super helpful, thanks!

@kylew6275 any time!

@@salmonella508 now I want to know what the obvious comment is...

Really? I've never seen any.. Which makes and models?

@@TheMarkList "handlebar weights" are on many bikes in differrmt forms. Some are floating suspended with rubber from the other end and the other floating and even adjustable reaching far inside the handlebar.

@@gearloose703 thats totally different than what this is. Not the same at all. I used to race desert moto and have an 890r currently. Vibration dampers versus an active tuned damper thats matching the front fork are two totally different beasts.

@@TheMarkList Yes handlebar & damper combination won't strictly affect suspension, but do affect feel a lot thus has a large effect on suspension as well. I don't care to mess with this stuff anymore but in short there is only two things that matter: what the rider can tolerate and what the wheel/rim can tolerate. Big auxiliary TMD is a research tool or a sign of a design failure.

@@FLG8r thanks for the compliment!

@@richardwilliams4596 nice, me too!

Yh it worked a charm until you get unlucky and rip the tube

@@Arfadezz yeah spoons would work 30 yrs ago on your Schwinn Sting Ray... but not on the world cup with dh casings and inserts!

@@anthonynazzal1958 let me see what happens when I turn my bars all the way to the side. Also it moves if you hit it on something just like your stem will move a bit side to side when you crash

Thanks! Also, next time you talk to the guys there, you may want to see if they can design the unit to fit into the bottom of the fork steerer tube perhaps? There’s a lot of dead space in there and that would be directly in the path of the vibrations moving upward, which might (or might not?) improve the overall feeling? Similar to how a mass damper in a skyscraper is situated in the middle of the building etc. I have an Orbea with the proprietary stem and spacers unique to Orbea so using this mount regrettable won’t work for me unless I swap out everything to a standard stem etc but if it could slide into the bottom of the fork steerer, oh man, golden. Absolutely universal then for tapered forks !

@@anthonynazzal1958 I know rimpact is doing that currently, but it looks small and maybe not enough force or the right frequency for downhill or super rough terrain. But that being said, i know nothing about the science and design of these things. I'm going to interview the owner of CounterCycle tomorrow or the next day. Stay tuned!

@@drill_fiend1097 yeah I was thinking Paris Roubaix and races on cobblestones...

When I raced XC in Alaska during the 90s, some of our longer races were essentially gravel races on dirt roads; but I would never want to ride a gravel bike on them because of the washboard. That stuff is BRUTAL! You can be cruising along at 16-18 mph and his that stuff and suddenly you’re just trying to slog through it at 4 mph. Something about the frequency just slows the bike down massively and quickly. The actual size of the bumps isn’t really as issue and shouldn’t slow a bike down at all; but when it’s a series of them, it’s like riding in quicksand. I really have to wonder if one of these tuned mass dampers might make a difference for that kind of washboard and might make riding an actual gravel bike on Alaska gravel roads feasible. Barring that, I would rather be on an XC bike with drop bars for those roads.

@@keirfarnum6811 I would say yes.. Especially if the frequency of the damper is tuned correctly. The guy at CounterCycle spoke specifically about what you brought up. Washboard situations where the bike is bouncing so much that you're kinda floating up on the peaks of the washboard... That shouldn't be happening and the tuned damper eliminates it.. I've been riding faster and faster on a local double black and my PR has changed almost every time down it...

@@cpshoot1146 you'd really have to pull hard to damage your tube. If you catch your tube with it, you usually can't move the lever.

that's a great question. I'll ask the inventor, Nathan.

Could be useful for gravel bikes.

They are $275.00

@@TheMarkList wtf the pricing is insane. I'll wait for the amazon basics version.

@@taol8258 I've paid for expensive fork upgrades that didn't even come close to what this does to your bike/riding

If they're BS, then why does the current downhill world champion use it while racing? And why does Richie Rude use one? and Aaron Gwinn? and Dakotah Norton... gee..I wonder.

@@TheMarkList because they're sponsored riders?

@@MTMXBL nope. They asked the owner/inventor for them. Trek reached out to the company to get the product and test it and it did so well they got em for multiple riders.

@@MTMXBL this thing is amazing. What is does to the suspension is really unique.. I'll go over it when I interview the owner of the company in the next week or so.

Agreed!

rimpact is developing one for the steerer tube.

@@taol8258 I'm sure a lot of companies will be doing that. Makes a lot of sense.

@@taol8258 That makes perfect sense; build the damper into the steerer tube and it’s can’t even be seen. I hope fork manufacturers start adding them.

Brand new tech for downhill mtb and mountain biking in general..

The bike industry is constantly trying to reinvent something that already exists.

It was banned in F1 for a reason. It works.

My 1973 Chevy Vega had one bolted on the transmission to attenuate engine vibration. That engine was a real paint shaker. Some tall skyscrapers have them to reduce wind sway.

@@dman900dl yup and formula one had them too..they work!
