Changing my bicycle hub

Yo.. today gonna post something different.. hmm for those who want to change their bicycle hub on their own or those who are interested to know how about bicycles parts, Please note that this is not a tutorial but my blog post.. ok.. before i start.. My 10 yrs old cannondale.. the hub has been with me ever since i brought the bike.. man.. super lasting! its time for me to change before it really..... mayb next time when i got time i start another post on servicing hub.. then you can see how bad the condition of my hub is hehe Just some pic of my old hub... Close up of the hub.. Ok.. now lets start.. First of all .. let's introduce the tools!! thanks hao for lending me his tool set Think he brought the tool set at giant or carrefour.. cant rem.. the set comes with the essential tools for basic servicing. (for normal bikes only.. for bike with chris king hubs or white industries etc etc high end hubs.. pls get the tools from the agent or just send for servicing ) the tool set comes with.. allen keys.. spoke wrench.. open end wrenches.. bottom bracket tool.. chain tool.. cassette lockring tool.. sprocket remover.. spanner.. screw driver.. etc etc for changing of hubs, you will only need the following tools: adjustable spanner (top), spoke wrench (mid left), cassette lockring tool (mid right), sprocket remover (bottom) OK!!next will be to use the spoke wrench and loosen all spokes!! wonder why this spoke wrench comes with so many sizes haha can even use on motorbikes..
Size 15 the right one.. ( note: clockwise = loosen, counter clockwise = tighten )
ok.. as seen in the above pic, unscrew the "nipple" and you will can remove the spokes..

( note: nipple is the technical term for that nut.. dun believe pls go wiki )

thats for the front wheel.. as for the rear wheel, there is an extra step before you can remove the spokes.

ok.. as you can see:

1) Wrap the sprocket remover around the cassette (or layman term - gear) 2) Lock the cassette lockring tool..

3) Lock the adjustable spanner onto the cassette lockring tool

4) Turn counter clockwise to release the cassette. a close-up view so you can see better.. oh ya.. btw in the pic.. i wrap the sprocket remover the opp way haha paiseh paiseh ^-^ if you follow the way i wrap in the pic you can never release it haha




ok once you loosen the cassette lockring, remove the cassette

man.. my cassette is damn dirty.. haha time for a wash with kerosene!!


Ok.. this is what you would except to see after you remove everything!!

Remove is easy.. the next step is going to be a big headach!!

Firstly let me introduce my new hub!!! shimano XT hub!! haha got it at a gd deal at rodalink.. i save more than 50% off the standard retail price haha also.. a cateye front light.. haiz my previous cateye has a battery leak.... and cant on anymore.. argh.. Pay more attention from this step onwards coz it can be quite confusing..

ok.. for my case.. its a 36 spokes rim.. so i have 36 spokes 18 each side.. as seen in the pic, the spokes are placed alternate. (1 up 1 down)
this is what you will see after you finish one side.. once you get both side done up.. it is damn messy..

Once both side of the spokes are place, its time to put it onto the rim.

as you know.. the wheels spokes are criss crossing each other.. what i doing here is call the "cross-6" if i not wrong.. at least thats what i'm taught haa there are many other different type of crosses also.. but since i only know this.. haha i can only show this..

1)Pick any of the spoke that are vertically downwards (count that as spoke no.1)

2)Pick (clockwise) the no.6 spoke (the no.6 spoke will always be the horizontal ones)

3)Cross no.1 over no.6 (another way to rem is bottom over top)

4) From the tire tube hole, the first hole clockwise, place the spokes in the lock it with the spoke nipples. ( as seen in the pic, the spokes are placed in alternate holes)


5)Repeat the steps and you will get this!!!

ok.. your front hub is changed!!

Next repeat what you do on the rear wheel.

After you are done with the spokes, place back the cassette and lock it.. this time round hand tighten will do.

wonder if you are thinking why my cassette is so small haha you are right! coz i'm not using mountain bike cassette.. what you see is the road bike cassette haha.. durace ones.. lol

OK!!

the next step will be the most headach and irritating part..

Truing your wheel!!!

Actually you are suppose to place the wheel set on the Truing stand.. its a equipment that enable you to true you wheel more precise.

if you are like me.. don't have a truing stand, what you can do is..

Just place the wheel onto your fork.. and true it accordingly lo.. this is not precise and really straining to your eyes..
for me i use the brakes as a rough gauge.. haha thats not the right way.. but.. make do with what i have ba hahaha


so that's all!!! once the truing is done, you can go and enjoy yr ride with your new hub!!!!


phew.. quite a long post..



ok.. stay tune for more updates!!


* for one whole day i only manage to true my front wheel!! and it is not really well done!! argh!!! tmr gg to true my rear wheel.. argh!!!!

  3. hi,
    Seek your advice pls.
    I'm using a ACLASS hub...24H. Dunno the model but the wheel is a 650c road wheel. Cassette is Shimano 10-spd.

    I want to change to a Bontranger Hub. Can I use any Bontranger 24H hub? or are there specifics which I need to look out for?

  8. Hi Asitaka, you should b able to reuse yr old spokes provided they are still in shape! ahah mine was quite badly bended and the threads wear off for some.. i tried to straighten it n reuse.. if you r not budget constraint, it would b gd if u change a new sets of nipples n spokes

  12. Thank you for your help, your pictures are great!! But, I really struggled to understand what you were writing... Can I suggest you ask a friend to proof read your blogs before you publish them. I don't mean to sound disrespectful, just some constructive criticism. Thanks again, Jimmy.
