Guys please dont underestimate the importance of a torque wrench. Overtightening any bolt can have severe consequences. Especially if you have any form of carbon fibre.

Stems brake or crack if you dont follow torque settings, and they come loose. By using a torque wrench you ensure that both or all 4 bolts are equally tightened. This goes for alloy or carbon..

We are talking about using a torque wrench and tolerance to preload the heasdet .

Don't confuse the headset with the stem .

So i bought some lube for my bike chain last week. I asked the dude at the bike shop what to buy and he set me up with an extremem conditions one and said this should do the trick. I applied it. After the ride my chain was all black and goopey (technical term) and the cogs were all full of gunk. I this kinda how it goes or did i apply to much or was it the wrong kind of lube?

Lube on a chain needs to be inside the little rings on the links and not much if any needed on the outside

A few things I haven't seen yet - first, don't spray bearings or suspension seals with water. You'll drive water and gunk in there and they'll wear out in pretty short order. Clean your bike with a bucket, sponge and brushes and rise off gently.

 

Second, the most important things to keep clean are fork and shock stanchions and drivetrain. This is where you'll save the most money. Read the sticky thread on chains and cassettes in the tech forum and learn how to keep an eye on chain wear with a ruler, not a chain checker.

 

Re the torque wrench question - superbike clutches don't have M4 aluminium bolts or carbon tubes. On bicycles, the torque wrench is more about preventing overtightening than undertightening. The most important one is the small one for things like stem faceplates and binders, seat clamps, rotor bolts and anything that clamps onto or screws into carbon.

Some good advice for those of us who really care and look after our steeds: -
