Are there tandem disc hubs that aren't 145? Are builders switching to super boost?

kimbo305 posted:Seems like machining a little insert to go inside each hub end and create a QR end would be achievable, esp for someone of mikemelbrooks' inclination. And then a dicier adapter to space out the rotor.   The redishing would bring the non drive side relative tension from ~60% to a floppy ~28%.

Hmm, maybe an endcap wouldn't work on the DS side... any extra width would push the cassette further inboard from the designed position.

It's not possible, but I have a 145mm tandem disc QR rear wheel I'd sell you for a very reasonable price. DT/Hugi hub, 11spd mtb cassette body, thread-on so you can run either drum or 6bolt disc.

Does anyone have a video showing normal drivetrain noise for a waxed chain? Single speed/fixed gear if possible, I'm seeing differing opinions online on how quiet they are and since it's the internet at least half of them are idiots and wrong. I think I'm just hearing the chain mesh with the cog/chainring but some people are claiming quietest drivetrain ever and if you have any noise you did something wrong.

I run a waxed chain on my track bike and it's relatively noisy - but especially if you run too much chain tension. Loose is fast. Deep wheels/disc exacerbate noise, too. Happy to record a vidya next time I'm out there.

I think it maybe possible for me to make up a spacer to push the freehub and or cassette over to a usable position. Spacing out the disk brake should be relatively easy as it's a 6bolt hub, and there are plenty of boost type spacers available.The wheels are missing the free hub so I am waiting for a new one to arrive.

Thanks, just seeing someone who I know has experience call it "relatively noisy" goes a long way to allay my worries. Word on the chain tension, I have always preferred a decent amount of play (plus my chainring is apparently nowhere near round so I gotta set tension off the tight spot).

I hate money and want a unicorn bike that doesn't exist. Current gearbox bikes don't have brifter options without cables sticking out the side which messes with my feng shui/~~aesthetics~~, or they require taking my hands off the hoods to shift which is no-bueno. So, bike I'm building right now will have SRAM AXS mullet setup. In a year though when e-bikes make gearboxes viable and wireless shifting is the norm I'll be real interested in a pinion gearbox and carbon drive. Could a frame builder convert a traditional bb to gearbox mount? If so, what would be involved? Just getting another frame is not possible in this hypothetical situation.

It would be pretty major frame surgery to chop out the BB and weld in the pinion fixture. I wouldn't bet hard on ASX/Pinion compatibility any time soon.

As a guess, I'd assume welding together a whole new bike frame would be cheaper than replacing the bottom bracket cluster like that

Pay someone to make you a pinion frame, then pay me the same amount (plus materials) to make you a prototype electronic brifter. It'll be a fun project.

Fair enough. I guess I should just be less of a punk and clean my chain like an adult instead of dropping 3k plus on the lazy option.

Is there a difference between alfine and Nexus that's more than just more/less fancy than? Is it that it's compatible with brifters or something? I have a Nexus 7 speed and an old rsx 7 speed brifter, is it even worth trying to make them work together? Obviously the shift pattern will be reversed but that's fine by me.

Slavvy posted:Is there a difference between alfine and Nexus that's more than just more/less fancy than? Is it that it's compatible with brifters or something? No. The cable pull is different and riding the nexus constantly in between gears is gonna gently caress up the hub. Nexus might even have different amount of cable pull for different gears so you can't really get around it. The same goes for alfine and the only compatible brifters are electric. I think I've seen maybe microshift bar end shifters for nexus sometime so I'd look into that if you want nexus / alfine and dropbars.

CopperHound posted:disc brake support. They make disc brake nexus hubs now. There's maybe no thruaxle nexus? I tried looking for a difference and comparing nexus 8 and alfine 8 the range is exactly the same and the weight is within 10 grams so I'm guessing the difference isn't huge.

I completely missed the tandem part my bad. And now I'm finally back where there's cell service. This isn't something I'd wanna bodge tbh. Any resources spent trying to make this work would be better spent lacing some gravel rims onto your hubs. The hoops you'd have to jump through to bodge this would most likely be a wasted effort or at worst damage the gravel hubs and also your body.

how much of a boomer/fudd am i for thinking electronic shifting and disc brakes on strictly road bikes is just a way to soak dentists for couple extra grand? have disc brakes suddenly gotten a lot better/have considerable advantages over double-pivot brakes in the last few years?

It's so 5 years from now you have to subscribe to an online service and be billed monthly or Shimano/SRAM will turn your bike into a single speed.

Listen buddy, if you can think of a better way to create value for Shimano's shareholders than forcing the entire industry to use a new standard they invented, they'd love to hear it.

Disc brakes rule and they should be on everything, cable or hydro, whatever they are objectively better. Electronic shifting with software updates and all the other modern tech bullshit attached is a revolting concept and you'll take my lovely cables from my cold dead hands.

Literally Lewis Hamilton posted:Electric shifting with rim brakes is delightful though Each to their own, good rim brakes work fine but discs are preferable for me. I don't really see the point of electronic shifting, seems like a huge increase in bullshit for a tiny weight and appearance gain. I also like the mechanical positivity of changing gears with a cable, I think it's analogous to a car with a clutch and gear shifter vs a button shifted auto.

I kinda understand the appeal of electronic shifting, in that it can do micro adjustments and timing optimizations that are just not possible with a mechanical set up. But no way I'm paying the price tag for it. And one of the beautiful thing about bicycles, to me, is that they don't require any electronic bullshit to work. Elegance in the mechanical simplicity. But I'm done with rim brakes. Disc brakes for life. Rim brakes are fine but given the choice I would never ever choose them over discs.

Elegance in the mechanical simplicity. This. I fundamentally do not want electricity and chips anywhere near my bike. The whole point is it works on muscle power alone, for me. If I want electronic assistance of whatever kind I'll just ride my motorcycle.

It's just an endless dance between a desire for as little play as possible vs a desire to not hear irritating rubbing. And that's assuming you don't have to actually take the pads OUT, yes let's just have 3 axes of adjustment all controlled by the one lovely lock nut where, again, you have to balance getting the pad perfectly orientated vs tightening it enough that it doesn't lose position and jam and kill you.
