comment Presta vs schrader valves
When I sent it over I was pretty sure there was a dupe here - can we close as dupe?

comment How long does a shifter, rear mech and front mech last?
So far my longest lived have been 28 years, shortest 4 years. Voting to close - this is subjective

comment What are the benefits of 700c23 tires?
I miss my old racer. 11mm front tire and 17mm rear tire on Mg alloy rims. Admittedly they weren't very strong - I shattered two wheels in 18 months, but it was a fast bike, and still the lightest I have ever owned.

comment How can I inflate Presta valve tires using a Presta compatible pump without bending the valve stem?
Agreed - I have had 8 or 9 presta pumps, and while some take a couple of fingers to close, none have been difficult.

comment Attach bottle cage to frame w/o mount screws
Surely at that point there is no grease etc so any shavings will be easily blown out? Also, the last two bikes I have owned have not had the bottom bearings sealed off from the rest of the tubes...which has always worried me

comment Why do some road bikes cost more than motorbikes? Are they grossly overpriced?
As kmm said - don't compare top bike with cheap motorbike. Compare it with top motorbike. Now it looks pretty cheap, eh?

comment How to shoulder a bike?
That is a big backpack, @Vorac...I now understand your problem a bit better. Not sure what I'd do with that - perhaps take a neoprene pad to pop on your shoulder - one edge tucked under your pack strap - to take some of the impact of the tube on your shoulder.

comment Is reversing the stem (pointing it backwards) a safe way to reduce reach length?
No - you misunderstand. I have no problems with the safety of a Dutch bike. It just isn't because the hands are widely spaced.

comment Is reversing the stem (pointing it backwards) a safe way to reduce reach length?
I agree with Carey - but I also think some of your assumptions are misguided, for example your comment on the Dutch handlebars.

comment Why is cycling on a road so much faster than cycling on a cycle path?
Oh, I'm not meaning potholes, but the smoothness of the surface at a closer level. If the tyre has to move up and down over small bumps the compression of the rubber uses energy.

comment Why is cycling on a road so much faster than cycling on a cycle path?
Heh - well, talking locally, the routes I take in to Edinburgh have a marked surface condition difference. The road is much faster, despite being longer. I only use the cycle paths for safety reasons, as the A71 is not great in the dark!

comment Protocol for downhill cyclist overtaking a car?
In the UK I have seen the opposite - the left turn signal is often used to suggest the road ahead is clear (as we drive on the left) but in any case I wouldn't trust the signal, as car drivers usually aren't as aware of risks to cyclists as I would hope.

Good point- I was thinking tread but wrote width.

comment Why does chain slip when I move my pedals?
@Carnotaurus - I updated my answer. I really couldn't see that first time in your video. Sorry.

Professionals drop the seat to avoid the crushing: youtube.com/watch?v=Cj6ho1-G6tw :-)

comment Why such a dramatic drop in power when the handlebars are lower than the seat?
This doesn't answer the question. The OP has indicated he has carried out many tests.

comment How to deal with long pre-bled brake line?
2 words - Duck Tape. If you are already using cable ties, tape will hold things from slipping.

comment About 20-30 people bike to where I work. What equipment/supplies should we have on hand?
