You guys are absolutely killing it with these videos

[@shredthetrack6858]

Great Interview with the öhlins Guys. Real honest answers!👍 I Like this Videos a Lot as there are so many ppl behind a win! Love to See the unsung heroes.

[@Phonophobia]

Nice to see Swen out in the wild - youngest apprentice of our class back in the day. Great guy all around

[@yattaran1484]

Can't wait the Race Day !.

Cheers John

Pole bikes are so trick... I really hope they can make a comeback

[@sety409]

I was so close to buying a week before bankruptcy what a shame.

[@kingflynxi9420]

Not often you see bikes with green SKF seals on the DH circuit

[@dyslexiusmaximus]

can you explain?

[@kingflynxi9420]

@dyslexiusmaximus most forks come stock with black rubber seals but SKF make the same seals out of green nitrile rubber that have way less friction. You get much better small bump sensitivity and less arm fatigue over multiple runs with forks that are more plush. Most teams work closely with the OEMs though so you don't often see the green seals.

[@rocky6162]

@@kingflynxi9420 do those wear out faster?

[@kingflynxi9420]

@@rocky6162 I believe the green seals should last longer as they effectively don't make as much contact with the stanchion but don't quote me on that

Been running a 200 front/220 rear rotor set up for years on my DH & enduro bikes.

[@vilimiryordanov8502]

Amen to that!

1:15 Fox 40 in the SRAM Service tent lol

[@Doggepp]

Probably a privateer that runs a rockshox rear shock.

[@michaelcawley7400]

It’s a limited edition ti nitrate coated boxer since rockshox had gold years before fox did

[@Doggepp]

@@michaelcawley7400 Its not. You can CLEARLY see that its a Fox 40. Even has the blue top cap fox runs, and the fox graphics. The only gold boxxer is a white one on Valli Höll's bike, which is a white fork on a white YT Tues, the bike in the vid is a scott gambler.

What's the word on those new TRP brakea?

[@vilimiryordanov8502]

They are great!!

[@vbspec94]

@vilimiryordanov8502 Did you spend a lot of time on that answer? Because is so enlightening and helpful

[@dgw6448]

Did not know that Pole bikes were pronounced Polleh

[@dit4963]

Wow, bike companies finally realizing that bikes don't slow down same as motorbikes, so it makes no sense to use the same logic when speccing the rotor sizes.

[@bimfred]

both motos and bikes use front for principal stopping power. Bikes just drag the rear a bit more.

[@Jeppelelle]

What? Do you think that bikes don't adhere to the laws of physics or something? Even if you would only use rear breaks while breaking there will still be alot of weightshift to the front, no matter what vehicle or any object in motion, when something is decelerating weight (or inertia really) will be pushed forward resulting in less weight on the rear & more weights on the front meaning more grip at front, so yeah, everything does slow down the same way, both bikes and motorbikes. And listening to him talk the spec sizing is about that particular riders break technique & preferences, not because of difference in slowing down between MC & bikes, so big rotors front and smaller rears will still be the best spec for 98% of all bike riders

[@dit4963]

@@bimfred "a bit"? Do you have engine brake, with which you can modulate the speed, on a bike? Are the braking points and the grip so unpredictable, which forces you to constantly modulate the speed mainly with the rear as the front needs the grip, on a motorbike? All these cause extreme heat and brake fade on the rear brakes, which makes it common sense that you want bigger rotors, or at least same size on the rear. Definitely not smaller as many companies do.

[@dit4963]

@@Jeppelelle Dude, you are completely off. Who said "bikes don't adhere to the laws of physics"? "inertia will be pushed forward"...you don't even understand or know how to use physics terms 😅 What happens during braking is the same, how you do the braking is clearly not the same. I explained why, learn to read before touching your keyboard. Read also "Ending the rotor size myth - Why you should have a bigger brake rotor at the back than the front" from Enduro Mountainbike Magazine.

[@thatguy2201]

​@@Jeppelellebigger brains than you or I have studied this, and bigger rear, smaller front rotor on MTB is the right way.

[@LaurentiusTriarius]

The age of electronics in suspension, dirtbikes and adventure bikes do pretty well without it, pls no 😂

[@nw7654]

The uci should ban all that really

[@Tancam17]

That is the stupidest thing I have ever heard 😂😂😂

[@yomommastupid]

crazy to see the difference between the big bike brands and the small ones....its like F1 where RB has all the budget but others dont....Pole bikes only 1 frame per rider available for a whole season that is mad...
