>That cylinder is a mass dampener also known as a J dampener in physics.The purpose is to neutralize high frequency low amplitude oscillations.Mass dampeners are currently used in Moto GP and were banned in F1 in the mid 2000s.The mass dampener can also be placed on the fork,above the bottom bracket and as shown on the rear swing arm/triangle on a full suspension bike.
have these been used on road bikes yet? i have a stiff track bike fixie, anything that could improve performance or comfort would interest me. i haven't paid attention to bike stuff lately so idk if it has been mentioned on GCN/GMBN yet. GCN has done a lot of videos on tire pressure so i could see them experimenting with tuned mass dampers.

Friendly reminder that there are multiple studies that show that the biggest factor in cycling performance is not the bicycle itself but rather the physical fitness of the cyclist. All having expensive gear ultimately does is effect your ride quality, but will only make marginal gains regarding ride performance and efficiency. If you're struggling on hill climbs, the issue isn't your bike, the issue is you. Take personal accountability, get in shape, and don't fall for consooomerism

Anyone else feels like absolute shit after crashing? it's not even the pain of it it's just the faith in your ability slowly dying inside. When I was younger it was whatever but now it feels like someone chipped away a chunk of confidence.

thinkin of buying a sick old mbs mountainboard with a brake on to make a long distance all terrain electric skateboard
im gonna use a top mounted battery 2 moters (maybe 4wd in the future) and belt drives, big 120mm urethane wheels for all road efficiency, no blutooth remote just a cable and throttle on the brake line for simplicity
but i have no idea about actual electric skateboard stuff like motors batteries and escs tho,
how do i minmax the electronics for maximum range over fairly hilly ground that averages out to be flat maintaining like 10 to 15 mph
and a compact charger for it i can take with me
any recs for parts?
i got money to put into this project for high quality electronics

Is riding on top end groupsets if you're not a top end cyclist stolen valor? Or is this sour grapes?

What groupset would you ride if you could get any groupset you wanted for free, but when/if you sold the bike you would have to price it as whatever groupset you ride now. That is, if your financial circumstances were no different and you were subject to the same "rules" as you currently as in terms of other people judging (because we all know unlimited wealth begets shamelessness), what do you choose?

Urbanist jannies apparently don't know what "PF" or "BB" stands for, so let me spell it out complete with AI sloppa to conform to nu-/n/ standards

This thread is for discussing a bicycle part called a "bottom bracket", in particular why there was nothing wrong with press fit bicycle bottom brackets, and moreover how it is inappropriate to put a tiny cigarette-butt sized bicycle bottom bracket that was designed for skinny steel bicycle frames, into the bicycle bottom bracket shell of a carbon fiber bicycle frame

Bicycle bicycle bicycle, AI sloppa, happy now? Is that better? YIMBY YIMBY parking minimums, suburbs bad, amsterdam good, there now it's on topic.

How is this guy alive? First one or two videos I watched, I thought he was just going for (You)s but they just get worse and worse. The only way this makes sense is if he has terminal cancer and he wants to die riding a bike and not in a hospital bed.

>be a noob cyclist
>hear a creaking noise
>could be from anything, pedals, saddle, shoes, whatever
>don't bother fixing it, just conclude based on youtube clickbait that it has to be the "bottom bracket" because in your baby cyclist brain that sounds really mechanical and technical
>repeat it on reddit and get other retards to follow suit
>entire industry abandons a perfectly good standard and is trying to reintroduce antiquated, small-diameter threaded BBs made for steel bikes on modern carbon bikes where it makes no sense
Is the anti-PF cargo cult the greatest psyop in modern cycling history?

These faggots should be strictly restricted to class F airspace, with well defined dimension and NEVER EVER LEFT OUT, sick and tired of avoiding them. Yesterday while flying a personal Cessna 310 from a buddy of mine and 3 weeks ago on the Dash 8 with the small airliner I fly for.

Is it the blimp trains time to shine?
Could this be used to get Ukraine grain to the rest of europe?

They have different rail gauge between rooskie and EU tracks but blimp can be handed off with out even slowing down

THIS CAN WORK???!!!!!!!
BLIMP TRAIN HOLEY ROLLER
RIDE ON THE BLIMP TRAIN
BLIMP TRAIN SAVE THIS COUNTRY
AND MAKE IT WHOLE AGAIN

Now Im on the edge of something
Wondering bout the blimp train
ooooohhhhaaaaa eeeeeaaaaahhhooooaaaa
Talking bout the blimp train
