Just getting started?
Here's a letter I wrote to my brother just after he got a new bike. Nothing
personal in it, but a lot of stuff that I've figured out over the years. Maybe
it'll save somebody time, pain, and money. Also, don't forget to check out
some of the cool stuff that works and can be found for
cheap

More stuff on bikes, just a whole list of small items I find useful.
On chain lube:
everyone's gone crazy over dry lubes, but having burned
up a drivetrain on them, I say they're crap. So does [name omitted],
a friend I road bike with who has a BS (MIT) and PhD (Ga Tech) in mech
engineering. Here's what I use ([omitted] used to use Pedro's synthetic
wet lube, but has since switched to mine): a 50-50 mix of "Slick 50"
(find it in the auto lube section at Wal-Mart, about $18 a quart) and
90 wt. outboard gear grease (about $4 a quart). $22 sounds like a lot
to shell out, but it's cheap for 2 quarts of lube when you compare to
$8 for a 6 oz bottle at a bike store. And it's way cheaper than a new
drive train. OK, mix the two parts 50-50, lay out some newspaper on
the floor and between the chain and back wheel, dribble it on while
pedaling backwards. Let it soak in a minute, then wipe it ALL off,
every bit you can. The only part you want to leave is inside the pins
and rollers, which you can't get to with a rag anyway. Whenever the
chain's dirty, use a brush on it first to knock the crap off so it
doesn't get floated into the chain's bearing surfaces (get one of those
Park brushes, or an old toothbrush will work). It usually comes off
as oil-dampened grit. If it doesn't, you're not wiping off enough
initially.
When it gets really skungy, you'll have to degrease the whole
drivetrain, but this is maybe a once-every-5-big-rides job. I think
there's a write-up on that the thin mtb book I gave you (but I usually
don't remove the wheels, nor do I have a stand like they recommend).
Just don't shoot any high pressure water spray directly at the bearing
seals; this can force water, or worse yet, degreaser, into the works.
Lets see, the shopping list-- and I'm not saying "go buy today", just
keep it around and pick these things up as you need them. Or maybe
you'll find other things that work better for you. In any case, these
are the things I've settled on over the years.
- Helmet.
- bottles & cages (half-check -- you'll need 2 to get past the
parking lot -- get another one).
- trail tool kit (that Park one I showed you)
- a spare tube; sometimes the rip's too big to patch
- CO2 inflator (Innovations in Cycling Superflate or Ultraflate -- they
use the cheap unthreaded CO2's, about $8 for 25). Cheaper, better,
faster than any mini-pump. Fits presta or schrader valves without
any adapters or even adjustment. Fits in your pocket, out of the dirt.
- gloves. I like Fox Longhorns, but use what works for you.
- kevlar spoke
- toilet paper in a zip-loc. One day you'll really want it.
- In cool weather, a $2 mylar space blanket. Keep it in the ziploc too.
- Glasses, either prescription or appropriately tinted sunglasses.
"Beats a poke in the eye with a sharp stick" isn't an idle saying.
- some sort of under-seat bag, or maybe a water-pack with a cargo bag.
Just big enough to hold the tools and tube.
- external, removable seals (Lizard Skins is the brand name here,
but there are others, including homemade, that work fine). They
keep the worst 98% of grit away from the real seals, and greatly
extend component life.
At a minimum, get one for the lower headset and one
for the rear shock. These are both expensive parts that tend to
get crud-blasted. After that, maybe one for the upper
headset, and one for the chainstay if you want to get fancy.
Shop tools you'll find useful:
- floor pump. Get a Silca basic model with a reversible chuck.
- chain brush; Park makes one with a comb for getting between cogs.
- a 4-5-6mm Y-wrench -- with this and a screwdriver, you'll be able
to adjust or replace 80% of the stuff on your bike.
- citrus degreaser. Finish Line makes a good one that cuts even the
chain lube I wrote about above.
- some kind of dry or semi-dry lube for your cables. They don't take
the beating the chain does, so you can use a dry lube to avoid
attracting dirt here. Also, a little bottle will last a long time
if you're just using it for this.
- chain checker tool. As chains wear, the spacing between the pins
gets longer. In turn, the chain wears the cogs and rings to fit the
worn pin spacing. Finally, the chain breaks completely, you put on
a new chain, and the old cogs don't mesh with it. But, if you change
the chain before the old one's completely worn out, you can get about
4 times the life out of a set of cogs and rings. A lot of people
say "let'em all wear in together, replace them all at once". This is
crap, because even a marginally worn chain will make shifting sloppy
long before the rest of the parts are significantly worn. It's also
really expensive to do things this way. Check your chain, swap it
out whenever stretch gets near the red zone or whatever the
checker indicates as worn. In this sandy grit around here, I get about
300 miles/chain; in your clay soil, you may get 500 miles/chain.
- And when you do replace a chain, get a Sachs M-55 or PC-61. Shimano
chains just aren't as good. Ignore the "USE ONLY SHIMANO PARTS"
warnings. Watch out if you've got a new 9-speed.
- And don't forget to join IMBA.
Enough for now. Off to lunch. -Rob
