[Closed] Rear speeding - good idea?

Er what?

Think I'll stick to my nice shifting 🙂

Get to fiddle with stuff.

Sold! Not sure about the rest of the benefits like, but faffing with bits of bikes is reason enough to do anything, pretty much.

Name sounds a bit like something dodgy people get up to in remote car parks late at night though, might want to think about a different term for it... 😐

Doesn't ruin knees as much as singlespeed but still fairly badass

isn't the knee thing a myth ?

The knee thing is totally a myth. I took up singlespeeding as rehabilitation after I wrecked my knee and it worked great. You stand up more, so while you're putting more force through the knee you don't do so at an acute angle.

I've tried "rearspeeding" (hmm) before, but since it needed an additional device to keep the chain on, I figured I may as well attach that device to a shifter and put a granny ring on.

worst of both worlds?

I find standyuppy climbing on a SS easier on the knees than sitting and spinning.

The only time my knees suffer is both cadence/spinning out when trying to keep up with geared bikes on the flat.

I front speeded for a short while- single speed at the back with a dérailleur, double at the front, no shifters but changed gear by reaching down and pushing the chain over with my finger. It worked but I'm still not sure if there was any point to it lol

Mountain biking?

I think you've invented term for something most people have probably done one way or another at some point...

But I am not googling "rear speeding" for fear of the 'niche' websites it will inevitably return...

Google 'rear speeding' and it comes uo with a link to this thread (good job on the page rank webmasters) and a few things about traffic accidents - i think you chaps just have dirty minds.

Maybe I got the knee thing wrong, I thought singlespeeding was hurting my knees - when going uo a steep rocky climb have to keep the weight back so the rear keeps traction so not standing up on pedals and then pulling up on handlebars and putting a lot of force through the leg in order to climb at 40rpm.

Worst of both worlds - I dont see it that way as it is cobbling together a useable bike from a bunch of spare parts which was the original ethos of singlespeeding whilst having a bike that is a bit more useable on a variety of slope & terrian.

I think another reason I like rearspeeding is a majority of drivechain woes come from the front mech, rubbing/rattling, chainsuck, much faff getting it aligned & adjusted right. So rearspeeding goes quite a way to achieving the simplicity of singlespeeding.

Wow ... using gears at the back....
I bet no-body had ever thought of that .... 😆

If you have all the old bits kicking around I guess it has some merit, but with new bits it's still a £50 drivetrain and you can put together a decent 1x10 drivetrain with a 10-42 cassette for under £90.

I'd go for "twinglespeeding" (2 at the front, one at the back) simply because there must be so many part-used 2x parts lying around. I tried a thringlespeed once.

It is about cost of ownership.
I am talking about using all the old 17T-32T sprockets (i found when i bought a new cassette only the 13T/15T was worn out) for commuting and hacking round the woods.
A decent 7/8spd chain costs only £10 and surely lasts quite a bit longer than a 10spd one?

For serious riding i am not sure I'd want a 10-42T casette, isn't the wraparound loss for a 10T something like 7%?

For cost of ownership you could go a long way before that was expensive - full 10sp double/triple for 160 quid. Never had longevity problems with 10sp and in reality having all those gears indexed and running smoothly must be nice 🙂

Was it? I didn't know that.

I must be doing something wrong then, as I seem to spend more on singlespeeds than on geared bikes.

You ride a Brompton AICMFP 😉

Singlespeeding, like many things in life started out with a few people doing something themselves for not much money because it was cool and grew into an industry with lots of people spending lots of money on products because the marketing tells them that it is cool.

Twisty, if you enjoy it - surely it's all cool.

I don't think 8s chains last much longer - certainly I've seen tests stating 10+speed actually last as well.

You 7 speed mech works on up to 9s (mtb) and 10 (road).

Try using your gears better if you wear out 2 cogs out of 7+!

I've tried a few set ups like this, CBA anymore, gears or not please (bar trying to get 3s on the Brompton).

think that putting a 14T and 21T either side of that cog in a vertical dropout frame is somehow offensive.

For serious riding i am not sure I'd want a 10-42T casette, isn't the wraparound loss for a 10T something like 7%?

No, you're right, for serious riding a random mix of shit from the spares box including three 17t sprockets and two 19s is far better... 😕

I want a good range of gears so I can keep a more optimum cadence and i also start to think about stuff like would I rather be driving 40T/13T at 94% drivechain efficiency rather than a 32T/10T at 88% efficiency.

Really?? Surely 'singlespeeding' started about the same time bikes were invented?!?

rearspeed like a boss.

Sorry but eh what??? How are you measuring "drivetrain efficiency" and WTF is it? Not trying to be shouty but seriously not sure what your point really is. Try that dirt cheap 10sp I linked to

The formula set out in

isn't a bad place to start. Drivechain efficiency is literally how much of the power you put into the crank goes into driving the rear wheel vs being lost in moving the chain and turned into heat by friction etc. Think about the last couple of links being pulled off the rear sprocket by the cranks, the pins/rollers of links are both under load and articulating which causes friction. For larger sprockets the angle of articulation is quite a bit less, hence the losses are less.

Love it, can I have a sticker with this on please.

I'll file that one....
Happy enough with my chain melting drivetrain efficincy 😉
Feels like we are heading down Chris Porters mechs and chains are bad...

How about 7 speeds, where every sprocket is a 17t. That way you could spread the wear evenly and your cassette would last 7 times as long. You could still call it a single speed because it would only have one gear ratio.

Could but that is a hellava lot of redundancy. Better to run two identical chainrings up front and two identical sprockets on the back driven by two chains.

I don't get it. You're talking about cobbling together (e.g.) a 1x5 setup ?

I'm not sure which in world it's "badass" to run a pile of mismatched crap that doesn't really work.

I certainly don't get it either and what is has to do with single-speed or why single-speed would even be referenced is a mystery.

So it's basically another name for "being a cheapskate bodger". Badass.

Badass because you need to put a bit of grunt into getting up hills, rather than than spinning up in a granny gear. In this respect rearspeeding can be a halfway house between manyspeeding and singlespeeding, hence the reference to singlespeeding.
My 2nd rearspeeder actually was a 1x5 made from mismatched crap (7spd ig 8spd hg, plastic thumbie from some 15spd dawes drom the early 90's) and i was really suprised at how well it worked! Have you ever tried to put together a bike using mismatched crap and a bit of skill rather than just breaking out the credit card?

No. I'm not badass enough for that.

In this respect rearspeeding can be a halfway house between manyspeeding and singlespeeding, hence the reference to single speeding.

But you are using gears so still nothing to do with single speed whatsoever. Okay so you are using a selection of gears that are higher than most riders but still geared none the less.

If I was to ever use gears again I would be happy with 3 gears (high one for road sections, same as gear I have now for off road, slight lower one for tricky uphills) If only someone would make a 3 speed (lightweight) hub changing using a wireless changer I would be likely to try it at some stage. I wouldn't be calling it rear speeding though...

3 speed internal gear hubs have been availible for over a hundred years. If you really dont want to shift it using a cable then i can hook one up to a servo if you want, yours for only £399.99

Yes, I am aware of Sturmey Archer. You may have missed my lightweight comments as a Sturmey Archer disc 3 speed for example weighs 1400g. So if you can make ether following I will buy one

Disc
under 500g
130mm OLN
Uses 15t cog for direct drive
Wireless changing via button that replaces brake lever bolt

When will it be ready?

Surely by putting a mech on its just a geared bike, regardless of the number of gears.

Part of what draws me to SS is the simplicity of it. And not having a rear mech to damage/twist/snap.

I'm not sold.

130oln? Road bike then?

And "rear speeding" had been around since the dawn of time. It's called "cheap shit bikes with 3/4/5 speed freewheels and gears that don't work very well."

Sorry, 135 not 130. Hoping that doesn't effect production time.

No idea. You'd have to check with someone who could make a business case stack up. Boris Johnson might be able to make something out of it.

The nice things about single speeding are the mechanical simplicity (no dangly bits, wires, levers) but also the fact that it forces you to push a bit harder all the time - either you're grovelling up a hill with your heart about to explode, or you're spinning like a loon to stay on someone's wheel, with your heart about to explode.

The only bad bit about SS is you inevitably end up going slower overall (at least I do), or just walking, which is annoying.

To me, this isn't in any way comparable.

It was directed back at twisty not you, twisty was the one offering to make a wireless changing lightweight 3 speed hub. The price was already set so he must have done his maths.

Yeah your weight requirement would be a problem. The sram i3 disk for example is 1.2kg, a lightweight freehub hub is 300g. Getting a gearhub below 500g would be very challenging it might need ceramic spur gears and stuff.

"[i]Have you ever tried to put together a bike using mismatched crap and a bit of skill rather than just breaking out the credit card?[/i]"

Yes. And judging by your posts, probably since before you were born.

About ten years or so.

And in that time I learnt - pretty quickly - that mismatched crap is just that.

So as far as I can tell, all you're doing is building bikes with gearing that's inappropriate to their use. I still don't get what's badass about it. You can slog your guts out grinding up a hill at 10rpm on any bike - just ride in the wrong gear. You don't need to build a special bike to do that. Put a 11-23 cassette on and stay in the big ring.

Totally don't get it.

Oh wait. It's school holidays, isn't it ?

To be fair, you could argue that the whole 1xn (for n>=9) with silly big sprockets is just bodging together something that's almost as good as a properly done 2x10 setup.

I think my 1x10 gears definitely make me badass. At least in my head.

Mr Jumper (is that of the wooley or dirt type). I'm just advocating an aspect of cycling that I have enjoyed. I like that it has an element of gear minimalism so it forces one to push ones body a bit. I get satisfaction from riding stuff that would otherwise be going in the bin (reduce, reuse, and cycle and all that).
If it is not your cup of tea then there is no need to get upset about it, I'm not trying to physically force it down your throat.

Wondering if I should actually make some stickers now

Yep, not easy, you may have over committed but I am sure you are up to the job. Let me know when you have made it and the £399 is yours.

And I don't want a sticker included thanks.

Being in a position where money is tight means you sometimes need to be a bit more creative, but you probably shouldn't call it badass 😉

Not all that surprised, the ti sprockets are massive, that would look daft unless you were a die hard cyclist!

I was a die hard cyclist, but this didn't make it any more attractive to her. Maybe if she herself was a die hard cyclist then it would have worked!

That's what I meant. No one other then a fanatical cyclist would want to wear a used 34t sprocket around their neck. Slow typing.

I had to buy her a silver one

Silver?

Pikey.

In actuality I may have promised to get one but then never bought it, 😆

Oh so that is what you really meant, not my fault if you write like an 11yr old

Oh teh ironing. Why did you reply after 2 months? 😕

Rear speeding! 😆 piss off.
