comment Accurately replicating the resistance felt whilst riding via a resistance fan diy turbo trainer
what do you mean by "statute to metric". Also, the cassette on the LeMond fan suggests you're probably looking at wheel rpm not crank rmp (cadence is crank rpm), and it looks as though they gear up again in the trainer. It might also be useful to point the fan at the rider rather than off to the side.

comment How to test the endurance of a frame?
It will also depend a lot on your budget. If you're spending more than, say, $100,000 on the contest then putting some of that into a little test rig makes sense. But if you're just saying "best one gets my stamp of approval" then you really need a volunteer crash test dummy to ride them all and see which ones cause major injuries.

comment How much does rider weight increase tire pressure?
@Floris I think you used cross sectional area as a proxy for volume? Which is more accurate for a "rectangular toroid" car tyre, but even for a bike tyre it's very close. And for the sizes of zero we're talking about, I agree that the difference is also close to zero :)

comment How much does a typical cardboard bike box weigh?
... and if you're shipping a velomobile it's even worse. It counts as a "volumetric weight" of a tonne or so, making it very expensive to ship. I could have taken it as luggage on the bus for less (including my ticket), because for some reason buses don't seem to care. Also, the courier driver expected to need a forklift to load it.

comment Bike wheel Assembly
Where did you get the spokes? Have you checked that they are the right length for the hub+rim and lacing pattern that you are trying to use? Have you looked at the other "how to build a wheel" questions here, or any guides other than youtube videos (that all seem to just assume you have the right length spokes)

comment Is it acceptable to cycle towards the centre of the lane on blind corners?
My only concern would be corners that go on long enough that a motorist could enter the corner and come up behind you without having time to slow down before they hit you. Long, sweeping corners in hilly areas are particularly prone to this because cycling uphill is even slower...

comment How to move a bicycle by bicycle
Often the lower bike is the better one, so you can put your feet down more easily without letting go of either set of handlebars. Otherwise you need a wall or something to lean the second bike on.

comment How to move a bicycle by bicycle
I find the opposite - it's better to lean on the second bike so you can "track stand" and the second front wheel doesn't lift up and flick into my front wheel. A bit of weight makes it more stable.

comment How to move a bicycle by bicycle
I've done this to move a tall bike (using another tall bike, obviously :) and used to fairly regularly do it with safety bikes. I did it the other day, 5km from work to the train station (I wasn't game for 20km all the way home). It's not too hard, go slowly and pay attention to steering.

comment Use a lock nut on a presta valve?
@tedder42 I've broken valves and pulled them out of tubes before too, but I can't see how that nut would prevent the breakage. Can you write an answer than explains it?
