New vid! :)
ОтветитьIt's back! Merry Christmas to bike nerds.
ОтветитьNever stop nerding!
Ответитьwelcome BACK!
ОтветитьFinally another Tuesday Tune!
Christmas came early this year!
lee mccormack talks about RAD(rider area distance) which is exactly the same thing as your 'spread.' pretty interesting how you both noticed how important this measurement is to bike feel.
ОтветитьGood to see you back making vids
ОтветитьThis is soooooo eye opening!
Finally, it makes sense now not only in my head that reach is critically related to stack height, something I noticed right away when I bought my Mondraker: plenty of reach coupled with a too low stack height, resulting in an unbalanced riding feel, mainly on the steeps, so did some work to bring the stack up (riser bar + 160mm travel from 140mm) and make the bike feel more balanced.
I can hardly wait for episode 2.
Cheers!
Glad we get another season of awesomeness! Can't wait until you're putting together dynamic case interactions with suspension tune, because that's the magic... and you're one of the few people who can make a useful explanation actually digestible.
ОтветитьGreat job. Looking forward to more knowledge bombs.
ОтветитьLooking thinner!!!!
ОтветитьSurprised you didn't mention the affect of BB drop and the subsequent moment around the axles/contact patch and how that effectively lowers the angles mentioned. The extra drop of 29" is one of their biggest advantages IMO, far less pitch sensitive.
ОтветитьGood to have you back, the simplest things are the hardest to understand usually....
ОтветитьTuesday tune here to break my brain again next ride
Ответитьthank you for coming back
ОтветитьGlad that the series is back. Happy Holidays
ОтветитьHi, can you please analyze further the differences on handling between the following senarios? terrain considerations, your personal preference etc...
1. long & slack (pole, geometron)
2. moderate long & slack (banshee, unno)
3. long & moderate slack (mondraker)
Cheers!
Excellent explanation! Love this stuff. Thanks for posting. Keep it up.
ОтветитьSpeaking of CoM, why can't we have a curving dropper seatpost/seat tube, so that when it's down it's positioned towards the rear of the bike and when it's extended it's positioned towards the front of the bike?
ОтветитьBike geometry tip #1... It's actually trigonometry.
ОтветитьIt seems to me MTB manufacturers are are doing a lot of RnD that's already been done by motorcycle manufacturers in terms of front end geometry. Right now everyone's obsessed with long low and slack but I haven't seen 1 manufacturer list the trail of their bikes, which is the main factor in how stable vs quick a bike feels, and the product of HA, fork offset and wheel radius. The manufacturers slacked HAs off to gain stability, then forks had to increase offset to get trail numbers back in line (think early 29ers with low offset and slow steering). That also increases brake dive. Another thing to consider is fork response. Slacker HA makes a fork feel more responsive over square edged hits, at the expense of increasing binding and decreasing responsiveness on big landings to flat. I think things have gone a bit too slack at the front end for trail bikes and its a bit harder to lift the rear over obstacles, especially as most of the bikes weight is biased rearwards with the shock, swingarm and drivetrain all concentrated there.
Ответитьgreat stuff!!
ОтветитьFinally a valuable MTB video without "shredding" and "gnarly" bullshit! You have some serious teaching ability dear sir.
ОтветитьI think having the endo and looping angles defined from vertical is more intuitive. (Larger == more resistance to endos) Great talk, otherwise!
Ответитьwhere did u get that mario outro track? its sick
ОтветитьYour channel is great man. So interesting.
ОтветитьAMAZING VIDEO!!!!!!!
ОтветитьNo idea if you're reading comments to old videos but an answer/comment to this would be awesome.
Since you made this video MTB geo has progressed one or two stages, HTA has got way slacker, reach has extended, chain stays have somewhat stayed the same, seat tube angle has steepened up. My question is this: Has mtb genre (XC, enduro, DH etc) geo reached optimum yet, or is there progres to be made? I know the industry as a whole wouldn't tell us, as they always want to keep selling frames and components for those frames. But how much recent geo change is technically required as opposed to manufactured to sell new bikes? (Downcountry as a manufactured geo/genre is a prime example)
