Not sure how all the chips may fall just yet, but I just may be acquiring a new bike later this fall. I am looking at a bike with 650c wheels and I want to get an idea what a dyno-hub as well as essential goodies will cost me.

I imagine that any wheel can be built with a dyno, correct? Must I purchase a whole new wheel, or can my current wheel be retrofitted?

I'm sure I will have more questions later...

A dynohub can be laced to any rim size. No retrofits. You will need to have a new wheel built around the hub of your choice with new spokes and new rim.


650c huh? As in ISO 571?


I don't think I'd be choosing that wheel size for a rando/LD bike. To limited are the choices in tires. And you can't get anything wider than 28mm or so.

The good news is that you can likely drop the brake pads by 6mm and use ISO 559, where there are some good LD/rando type tires. But you will need to look at frame clearances.

kingston 

Agree. 26" rim is the way to go for what you're trying to do.

steve-in-kville 

There's a reason for it. Like being short.

Just checking out me options before I drop the hammer on this project.

Glad that you are viewing this as a Project.
Any successful Project that I've been involved in from building a bicycle for myself to implementing a new supply chain process for a corporation has several necessary steps.

Scope: What precisely is to be delivered on completion of the project?
Perhaps: "A new Rando-ish bicycle for myself."

Quality, Budget & Timeline:
Perhaps: Factory built complete machine, <$1,000, Delivered by Jan1,2017

Primary Requirements:
Size, frame material type, wheel diameter, drive train type, brake type, tire clearance, fenders, dyno hub, lights F/R, braze-ons, rack F and/or R, etc

Secondary Requirements:
Color, saddle, bars, stem, tape

Beware Scope Creep:
A simple fixed gear steel framed machine can become a budget busting long delivery custom festooned w/ doo-dads in no time at all.
That can be Phase II if the original Project is successful with lessons learned incorporated.

And quite the project it is!

So, lets avoid the entire wheel size issue for the moment (I have a thread about this going in SS/FG already) and concentrate on dyno set-ups. I want to be able to run a headlamp at night and charge my phone by day. Maybe even both at the same time perhaps!?

What make/models should I start looking at? Let's start there....

Bandera

Like so many things in a Project one primary requirement may run afoul of another, for example the Wabi 42cm that you are considering in the other thread comes w/ 24 hole 650C wheels while the popular Son 28 gen hub for example does not come in 24 hole drilling. You'll have a spare Fr wheel and add the cost of another 32 drill 650C w/ dyno hub to the budget.

Hmm....See why thoroughly documenting requirements and resolving conflicts/reprioritizing Before the acquisition phase pays off in a deliverable that meets Scope, within Budget and on Time?

Silver Shutter Precision PV-8. Hundred-and-twenty bucks. Next question.

I don't know where @Bandera came up with that budget, but I'll take the over.

steve-in-kville 

The above is one of the reasons I am shying away from the 650c wheel. As I look deeper into this, I may return to plan A, which was upgrade all my stuff on the Kilo (dyno included) and buy a new frameset down the road.

Boom. Done.

Steamer

That wasn't my point. There is nothing wrong with small wheels. But 571 is a pretty lousy choice for randonneuring at night in the Keystone state. I strongly recommend you try to budget a new 559 wheelset and tires.

kingston 

You may be able to keep that project under a grand if you're careful

steve-in-kville 

Where did this $1000 budget come from?! I don't remember posting anything about that.


(Glad your looking out for my bottom line, though!)

steve-in-kville 

I see. Well, I hope a dyno don't run me over $1k!

kingston 

If you can build your own wheel you should be able to keep it under $200

Bandera

A Hypothetical $ along with all of the other examples (hence "Perhaps") from Post #5 like a Perhaps delivery date of 1/1/17 as an example of Project Planning methodology for a Complete FG Machine.

Feel free to provide your actual requirements not spread over multiple threads in a couple of sub-forums to get more precise input from forum members, or not.

as an engineer, I have to say that nobody ever properly defines their requirements. I find it amazing how bad the situation is. So I can hardly blame the OP.

"I don't know my requirements, but I'll tell you if you don't like the design" -- every manager.

Bandera

This what I got paid the medium-bucks to do:
Hammering Project Process down every level from preening executive level "management" to the dude/dudette responsible for delivering a component in-spec/on-time/within budget way down the project timeline.

It can be done, and I'm Done here just as I'm retired from PMP duties w/ the Fortune 500.

There's no one right way to build a bike. When I build a bike I just start assembling parts with a general idea of what I'm trying to get when I'm done. When I have a big pile of what I think is just about everything, I put the whole thing together and continue to add and swap parts forever. I also never finish on time or under budget. Sometimes I even start a new project before the previous one is done which really screws up the schedule. It's a hobby not a job.

+1 on the Shutter Precision hub. Inexpensive, lightweight, low drag... we live in amazing times, don't let anyone tell you different.

Reading your message, I couldn't help but think of this old cartoon about project-managing a tree swing ...

Everyone's participation in this thread, as well as my others, is greatly appreciated. I've been been budgeting for this all summer and finally have the means to pull this off without selling any organs or something. I am trying to get a feel of what is out there in the world of dynos, put together a budget and establish a timeline. I guess you could say I am in the research stage!

StephenH

You CAN take an existing front wheel, disassemble, and re-use the rim. Maybe the spokes, but if the geometry is different at the center, then you'd need new spokes. Be sure spoke-count matches the hub you're going to use.


Better idea is to keep the original front wheel as backup/spare wheel and just go with a new one.

unterhausen

I don't expect much change in the dynohub world in the near future. I suppose Shimano could decide to make some better hubs. I'm perfectly hapy with my SP hubs

steve-in-kville 

I talked with my LBS today and got some ideas on having a pair of wheels built. He made some recommendations as far as components are concerned. Dyno choice is still mine, as long as the hub and rims are the same (spoke wise).

The big thing at hand is what bike this will go on. I originally was gonna set up my FG with this, but wisdom tells me otherwise. My Tourist is set up to pull the BOB, and does foul weather better than the Kilo.

This sucks. I finally have the $$$ to do this and now I am getting all indecisive!
