REAR SHIFTER CABLE HOW TO

When installing new rear derailleur shifter cable I was suggested the following:

First set H limit screw (cable is not attached)
Move the derailleur by hand inward to adjust L limit screw

H screw controls outermost limit
L screw controls INNERMOST (towards the center of the hub) movement

Before attaching derailleur cable:

Screw in barrel adjuster ALL THE WAY IN
Then unscrew it 8 clicks
Then pinch the cable to the derailleur.

Adjustments:
The chain does not move towards inner cogs - too little tension, tighten the cable
The chain does not move towards quick release side cogs (outwards)- too much tension, loosen the cable

General principle:
More tension moves the derailleur towards the center of the hub (inwards)

LIGHTS FOR NIGHT RIDING

I don't know about you, but I can't spend hundreds of dollars for a bike light. I buy lights here (Magic Shine):

So far no problems, delivery times are a bit long but they are reasonable.

I have a 1000LM Magicshine light, did 4 rides in rain, long term review will be posted in the spring

Hard obstacle- straight line pls!

Met an experienced biker today he told me this:

Try to cross an obstacle (up or down) in a straight line. Build a line in advance, turn and maneuver in advance so when it is crunch time (something hard to go over), you are traveling straight as an arrow! Build your lines so that you travel in straight lines as much as possible in general!
