It's interesting what you find when you work on bikes. First and foremost, bikes are usually delivered with the absolute minimum of grease and lube to allow it to function from new, but often this is nowhere near enough for serious use. Headsets come barely lubed, "hidden" items like bottom bracket shells are assembled dry, and hubs with just a faint smear of grease. For instance here's a almost new medium level Shimano wheelset as opened, it's lubed, but barely so....
Now a ton of grease isn't the answer either, but you have to remember the bike manufacturer would go thorugh a LOT of grease, and to keep costs down, it wouldn't pay to be "generous". I find a hub like this, repacked with the "secret" cog grease responds amazingly well. It usually takes about 300 kms to bed in, afterwhich it really starts to roll better than it ever has. I have had many a customer tell me "the bike really seems to sing " and I still remember the " I nearly died down Mt Mee" comment!
Here's a "typical" year old road headset as found ( dry ), the motorcross waterproof synthetic grease I use ( NEVER wash out ) and the final result how it should be done. Do it once, do it right!
Here's a mate of mine from way back, who recently had his nice Trek looked at by a local bike shop. Now to be fair most people would overlook this, but when I mention even looking at rear derailleur jockey wheels in a CogDoctor service, it's because you can find things like this.....
Why even have a bearing if it's seized and wearing incorrectly like the bush on the right?? Best I've yet seen Paul!
If you get your bike chain "cleaned and degreased" it'll end up something like the left picture. Sure looks clean, and that chain was washed in a bath of degreaser with a typical bristle brush. What you'd usually get in a bike shop service. But put the same chain in a Ultrasonic cleaner for five minutes, and look what you find....
This even amazed me first time, I thought bathing it twice in degreaser was ahead of the pack! Ultrasonic action comes in at the full overhaul, or is included for free at any level if you do a one time upgrade to a removable link on your chain ( $10-$20 ). I have them to suit virtually any chain, including Campy. Highly recommended!!
Drawing form my experience in the Auto industry, here's an example of one " outside the bicycle industry" product I use to bring tired and tarnished frames back to life. It's just amazing, especially on light coloured frames that tend to "stain"...
Anyone can buy bike tools, and let's face it, a bicycle isn't brain surgery, but while anyone can read the Park Tools repair manual, do they have years and years of experience ( ie already made their mistakes! ) have they built and serviced many hundreds of bikes, and most importantly do they have all the nuts, bolts and odd parts that years and years of owning a bike shop leaves you? Small invaluable items, you just can't buy most of the time.....
More to come...Greg.
Did you know the rolling resistance of a tyre is twenty times the bearing resistance at the hub? Or that the bicycle wheel is the strongest man made construction for it's light weight?
