BikeTechWheelBuilding

 


 

Introduction/Definition/etc

 

Wheel building is putting together the parts

of a wheel and a whole lot more, but it seems to be

a rite of passage for a bike mechanic, so I'll

get into it a little...

 

 

Body

 

As I've been learning more about bike mechanics, I've found that

building a wheel is a rite of passage for bike mechanics...

 

My first was a dynohub (generates electricity say for a headlight,

but built into the hub instead of those old bottle ones on the wheel

tires, of our generation). Shimano disc brake model, to be more specific

DH-71 or similar, and got a lot of help.

 

Wheel Anatomy and Terminology

 

Let's step back for a moment, a bike wheel contains many parts,

starting from the outside,

 

the tire, which rubber hits the road, so to speak,

the tube (while not all have tubes, most do, it's inside the tire,

and the valve (Shrader like a car, or Presta needlie/ thinner & different end...)

the rim, which is the metal loop that holds it round, hopefully ;-),

the nipples which go through the rim and hold the

spokes, wire thingies, though some can be solid rims,

[ called something that I've forgotten, at the moment, ]

the hub which is the spindle type thing in the middle,

the back wheel probably has a bunch of gears with teeth,

called a cassette or freewheel/ attached to the hub,

but look at the front wheel instead, it's easier/ simpler ;-/

 

The hub has an axle and likely a quick release lever holding it

onto the Fork (front fork, or drop outs

(metal slots/ horizontal, angled or in special cases vertical)

and lawyer lips (ridges on the end of a quick release drop out

possibly holds the wheel on if the Quick Release

lever is loose), but don't count on it...

 

Older bikes and BMX (trick bikes) are probably solid axles

and use nuts and not Quick Release (hollow)

it is also a security thing, as Quick Release means

quickly stolen too...

 

A diagram here would help...

 

 

Process

 

 

Building a wheel is putting all the parts together,

though the artists and craftsmen / women

do a lot more, selecting components appropriate

to their use (I'm simplified, have a  relatively cheap hub,

find a rim (some take brake pads against the rim,

others are disc hubs, and you'd be amazed how many different

rims and hub types and designs there are out there...

Mavic seems like a good brand for rims)

 

Anyways, choosing the parts may depend upon your

resources, the hub was located a long time ago,

from VeloOrange.com a local specialty place in Annapolis Maryland

really rather cheap $50 (down to $30 when discontinuing)

by comparison to the Shimano DH-71 at ~$110

 

Found a rim second hand, for $20 at a local Bike Coop/ Youth Program

and well, that leaves spokes.

 

It would cost about $60 LABOR ONLY for someone else

at a shop/store to build the wheel, and they can probably do it

in about an hour, (about their hourly rate),

assuming nobody else in line,

and other pressing shop business,

or even if they have that experience level on that shift...

 

It's going to take me/ you a lot longer, but once you learn,

even if you decide you don't like it, and want others to do it,

you will have learned a lot...

 

Calculating Spoke Length

 

SpokeCalc programs exist online, Excel Spreadsheet

(convert to free and open source, OpenOffice.org, watch for macros)

by Rinard (see SheldonBrown.com ... )

 

This requires measuring or looking up the dimensions

of the hub, which if I didn't have such an odd hub, would

be a lot easier...

 

Enter numbers into the SpokeCalc, ( or get a shop

to calculate for you, keep in mind you will probably need to buy

something, and well, do you have all the tools?  how about

a spoke wrench?  There is a winged one that is nice,

and there are different sizes... Park's are color coded.

Maybe you need a multitool, or a tube?)

 

Spokes cost about $60 for 40 (36 spoke hub, (most are 32, but I'm

special ;-), and some spares, nipples included,

the Art of Wheelbuilding book recommends

Brass Nipples, but most places round here don't have them...)

 

 

Spares

 

Come to think of it, get some spare spokes of your length,

for my 26 inch wheel with dynohub I'm in the 251 mm range,

depends on your hub, rim, etc... and you can't really change them

yourself and need the right size...)

 

Spokes are only about $1.50 each and you are going to break

spokes eventually, especially on the back wheel,

but that will be more involved, as you will likely

have to remove the cassette with a freewheel remover

(special nut tool that fits into the hub to get it off)

 

Sourcing and Parts

 

Would have been much cheaper to have bought online somewhere,

but would need SpokePrep (lube on the nipples, which are nuts

basically) specialized bike Loctite or similar, Effective Cycling

mentioned Linseed Oil, and well I bought a lot, it's combustible, and Toxic

so I'll just stick with buying locally and getting them to put

some on for me...

 

Tools

 

Aside, start getting the tools you need, in the long run,

might be better off.  I'm disliking the condescending sales

people from stores thinking you can't learn this,

you need us, ad nausium, to do it for you...

 

Lots of times, as a bike commuter, hearing leave your bike

for a week in the shop is not acceptable.  Even if you have

a spare bike (a good bike, say and a Beater (city knock about bike))

being without your bike is a pain...

 

And, well, sales people may never be mechanics,

basically why they are in sales...

 

A Spoke Ruler, is about $10 from ParkTool.com.

A Caliper is about $20, or digital is $50.

 

Get someone else to measure your first ones,

and get to know your Local Bike Shop (LBS)

as they are good to know.  Warehouse places

like PerformanceBike may have cheaper prices and

larger selection, but there is a good chance you need

service too, and they suck at that a lot of times, IMO...

 

Repairs at Performance, almost non existent,

mostly they put together new bikes to sell,

AFAICT.  Maybe look up the right parts,

but anyway, I go to all the local stores, and know

many pretty well...

 

How they treat me, in some instances, determine

how frequently and how much I would spend with them,

versus other places.  Vote with your money,

sometimes your feet...

 

Exit Stage Right

 

But if you'll excuse me, I've got SpokePrep from the other day

drying, and need to build this wheel.

Enter Stage Right

 

OK, tried it, and it's elliptical, instead of round.

The spokes won't reach the nipples on some parts of it,

for 5 or 6 spokes from the left hand side of the hub.

 

I did the Schraner Method, as best I could follow it from the book,

instead of classical/ traditional, because I don't have that method

in the book to follow. and maybe the measurements weren't right,

I generally don't get the results that others do from

written instructions, hence wanting the video and

multiple sources...

 

So likely calming down, taking a break,

looking for other resources I already know about,

checking with other people and places

(BikeForums.net ?)

 

Learning isn't always easy nor fun,

will be better when get some more positive

results.  Until then, that's where the learning happens,

like old science experiments, it was in how you

wrote up what happened and what was learned,

we had a hypothesis in science...,

 

Here, I'm guessing it's learnable,

and was going to call this Wheel Building for Dummies,

though I dislike the book series, just some

of the basics, step by step, and learn as you go along,

hopefully nothing tragic, Crash Test Dummies, or anything

happens...  Oh, and add a disclaimer,

 

Disclaimer

 

Your mileage and experience may vary.  Do at Your Own Risk.

(Another rite of passage is working on someone else's

bike.  Many people are nervous, Bike Coops take

used parts , volunteer labor and you work on your own

bike, with their tools, and maybe some advice from others,

as one class I took put it, most of the stuff on bikes

is out and doable, unlike cars/ motorcycles, etc with

more toxic chemicals, combustibles, etc.

 

There are risks with bikes, keeping hands/ fingers

out of moving parts.  Wearing eye protection (goggles,

glasses/ face shield), an apron to keep grease off your

nice clothes (BTW, most mechanics wear something dark,

keeps the grease and grime from destroying light clothes,

I've modified that some to suggest some Bike Coop places make

reflective logos when making t shirts, to have

the best of both worlds, still hot in the summer sun,

but at least more likely to be seen by cars...)

 

 

We Return To Regular Programming

 

Anyways, that's it for now.  More as it progresses...

Back to the books, and others...

 

Maybe just go with Sheldon's and skip Schraners

Method?

Truing

 

Once built/ laced (spokes put in), I'll need to True

(make round) the wheel, and well, that will be a whole

other page here... :-)

 

They say it takes patience, and well, with me,

that is usually in short supply...

 

 

Resources

 

Books

 

Art of Wheel Building by Gerd Schraner

(high end stuff, but good overview of the art,

might need more of the science, see below)

Bicycle Wheel by Jobst Brandt

Avocet

(haven't gotten it yet, might be useful)

http://www.amazon.com/Bicycle-Wheel-3rd-Jobst-Brandt/dp/0960723668

 

 

Effective Cycling by Forester

MIT Press

(of my generation)

and a lot on culture and advocacy.

http://mitpress.mit.edu/catalog/item/default.asp?ttype=2&tid=5650

 

 

Bicycling Science

MIT Press

(theory and history of bikes)

http://mitpress.mit.edu/catalog/item/default.asp?ttype=2&tid=10063

 

 

Zinn And the Art of Bike Maintenance

Zinn is a popular magazine writer on bikes, has books on road and mountain bikes

(haven't really looked at them yet, but heard some good things)

 

 

Park Manual

ParkTool.com , well, makes tools, specifically bike tools,

and one of the most popular, but not the only. 

The manual seems to sell the tools,

instead Effective Cycling talks about how to build tools

for a home shop too.  Like a Chain Whip is really just

some chain on a stick...  You will eventually have some extra

chain, so why spend $20-$60 on a chain whip?

Pedros,

Back in the day, mostly oils, and tools, but are growing since I last checked..

 

CrankBrothers

make a nice multi tool, and some eggbeater pedals

and many others...

 

SheldonBrown.com

Free online bike mechanics info,

more than you wanted to know, and slightly dated,

(notable John Allen is updating it) but start there anyways.

Then learn from other places to understand what he's talking about...

For most things bike mechanical, but some don't like him, go figure...

Sheldon was the first to really put stuff up online,

when the World Wide Web/ Internet was new, and he's now gone,

died in 2008 of heart attack, had MS...
