Red lyrik with flight attendant from Jacks yt, also showed off a red Zeb with flight attendant as well.
@Primoz, wasnt your comment about HP bikes in general, and that was before the GT bike I think.
Either way, just poking some fun
Side note, I pulled trigger on a V2 Druid, and am very much looking forward to it. Ive been mullet HP curious since the days of Balfa, but hadnt actually spent any time on a modern version of the system. Confirmation bias and all that, I'll soon know something about something
Don't remember the specifics of the comment to be honest, I've said some seriously stupid things over the years, but I just can't see high pivot idlers being the norm in a few years. Using Dave Weagle's patented solution (if it wasn't patented of course) maybe, otherwise I doubt it.
I get you, I too am curious, just not enough to buy one. Bought a new bike last year, recently finished it off and now I'm good for the next few years.
And I'll still eat the hat if needed. I've acquired a taste for them after all 😂
If gearboxes ever take off (doubtful) in the main stream, isn't the most theoretically efficient gearbox a non-concentric output shaft, single stage gearbox like Effigear but actually reliable? If so, that could make HP-ish bikes viable for shorter travel bikes. The trick would be to make the gears selectable on both sides, so only the engaged gears spin. Such a design could approach a derailleur setup in efficiency. But good luck getting two gear selectors to reliably engage at the exact same moment when shifting under load.
A single stage gearbox is a no-go as it reverses the direction of rotation, Effigear uses an 'idler stage' in the old design that makes the two shafts concentric in the current design. But yes, having the output not be concentric with the pedals GREATLY simplifies the gearbox design and gives you the possibility of playing with the pivot location. A best of both worlds.
But that's an 'if gearboxes take of'. I'd expect HP idlers to be more popular than gearboxes unless something drastic happens on the gearbox front.
Looked at the other forum topics before I posted this question. Still not sure if this is the right place to ask my question but it is about brakes. More of a setup question
what angle are most people going with for their brake levers on a DH rig? I have a 2016 Giant Glory
thanks
A question for the cockpit topic maybe?
sent you a private message
Ya, i know there is an initial stage to flip the direction, but that should have pretty low losses.
My dream is two road cassettes right next to each other with one flipped, and a single chain connecting them. Somehow, some way, a selector like a derailleur slides the chain up and down both cassettes at the same time. As each cog moves up or down in size, the other cassette moves the opposite, so there is very limited chain slack negating the need for derailleur pulleys. Two 250% road cassettes would then give us the mountain bike range needed in a compact space with minimal drag and freedom for pivot placement.
EDIT: like this, but two road cassettes and a chain since sliding belts on CVTs have poor efficiency

Shimano holds a patent for that, handed to them by Honda. It's what prevented Hayes from popularizing the PeteSpeed gearbox after they bought the design from B1. And you can be damn sure they'll keep it sealed until they have milked the rear derailleur for many more years.
A US patent? Because those expire.
If it was superior, it would be available in other markets. Shimano would also be producing it and making money off it right now along side their derailleurs. The high end market, road or mtb doesnt even come close to the entry level market, and that system is always going to be too complex, heavy, and expensive for that application.
Ha, I bought one anyways. Some light sanding and a coat of black paint should be fine, provided I cover the important spots with some masking tape. Not a big fan of having huge red calipers sticking on my otherwise pretty boring colored(grey/black/brown) bike.
interesting. how long do design patents last? I know it's 15 year in US and I think it's 20 years internationally.
I think Norco has some new e bikes in the works but I thought they would all be high pivots...
Fun fact: Shimano is actually about to put out an auto-shifting hub/derailleur for the low-end market.
Sometimes it isn't about pursuing new venues in search of innovation, bur about stifling the ability of your competitors to do it. Many times in the past a brand bought patents and shelved the invention only to avoid rival brands developing alternative solutions to those marketed by them.
I know I pasted the link of a piece about the whole Honda Racing/Shimano/PeteSpeed/Hayes conundrum a long time ago in this very thread. My memory isn't as good as it used to be, but the whole thing unraveled at the start of the century, after Honda decided to put the RN-01 to rest. Let me Google a bit and I might be able to get it back.
That’s the current model. This guy just has some weird diaper on his.
New VLT Sight and Range are both high pivot.
So now random kooks are covering bikes?
Everybody stop doing this. It isn’t a big deal, it’s a bike.
Seems like ebike shaming is becoming a real thing...
looks exactly the same as current range/sight VLT but I would bet my left nut their is an idler on the driveside, presuming a swap to bosch too.
I have the current range VLT, it's fantastic. There is minimal Pedal Kickback so the idler is an interesting choice, will be even more interesting if the axle path is rearward considering the bike now has 462mm Chainstay.
You can see the main pivot right next to the BB. The new bikes pivot is (ahem) higher…
Fuck me, had the exact same idea literally days before the Shimano patent was publicly shown in all the news outlets!
Patent trolls. Also companies buying out other companies just to enforce those patents onto competition and earning money that way.
Just make a red Zeb already. I have the new Lyrik on my SST and and love it. my Privateer could use the Charger 3 and yes, I’m that vain.
Couple of months and that might come true
And, a couple of months and that might not come true.
It's a Fork. Do the shims, o-rings, air shaft and oil have to be colored red also?? Or would that be too much 'this industry™' and needing another thread about cost-overrun?
i feel before painting lowers they should make fork run decent out of the box instead of feeling like wooden sticks
