comment What to use to clean your chain (and cogs)?
@Benzo: I did not want to imply you should not clean the chain at all - I just wrote that you should only wipe it off from the outside, and not bathe it in solvent. So there's no contradiction :-).

comment Does gear ratio affect Power?
As to max vs. efficient: Most efficient would be like a car - the speed/cadence which lets you travel the longest distance before you run out of fuel. Like a car, that is not necessarily the speed/cadence which gives you maximum power. And higher cadence generally means lower gears.

comment Does gear ratio affect Power?
As to the power thing: What I meant to say was that it depends on where you measure the power. If you measure power at the wheel, it will always be the same for the same speed and terrain. However, the power that the human has to exert may be different.

comment How much rest (tendon or ligament), for a novice?
Hi, and good question! Just one (meta-)comment: To comment on answers, just use the "add comment" under the answer. If you comment the answers in your question, it's rather hard to read...

comment What's a good bike lock that costs less than $30?
And BTW, yes, there are battery-powered angle grinders. HOwever, they're typically not as powerful as the ones that run on mains power, so cutting will take even longer.

A high quality U-lock made from hardened steel is practically impossible to cut with a bolt cutter. You'd need an angle grinder.
