comment Bicycle Geometry 101?
I wish I did. The main modern philosophy seems to favour a rear weighting bias. The other major philosophy seems to be a front loading and a more even front back weight distribution. Each requires different geometry. Bicycle quarterly would be a good source for the latter, but I am unclear if there is a single volume summarizing what is known. Much of this knowledge seems to come form 30's and 40's, little was written down and most of it was lost with shifts in the bicycle industry to sport over transport. It seems that right now many are rediscovering this later handling philosophy.

For those who are excessively ground challenged, DirtySixer makes some of the tallest bikes around.

comment Weird gear ratio for a couple of seconds after crash
Seems very plausible. Given the speed prior to the crash, the OP would have likely been in the big ring. This is just my personal preference, but I would add a statement that its all speculation and the OP should have the bike checked out at a bike shop if other odd behaviours begin.

comment SON 28 Hub Dynamo “Rotation Lock”?
There is a bit of resistance due to the magnets, if you are holding the clamp/quick release by and and spinning the hub/wheel the axle will likely spin on the clamp/quick release due to this resistance. Once in the fork the axle will be held firmly in place and the hub will spin on the bearings. This resistance is less once the hub starts spinning faster and is only about 1 watt (small compared to wind and tire drag).

comment Bicycle Geometry 101?
Optimal geometry is also heavily influenced by handling philosophies. Calfee and Grant tend to share one perspective. Not to take away from either as Grant has a great series of articles, but this geometry is based on a firm perspective on how a bike should handle both with and without a load and how loads should be distributed on a bike.

comment What effect does seat tube angle have?
For leather saddles (e.g., Brooks) a shallow seat tube angle can help to get the correct offset. Leather saddles which tend to sit further forward relative the seat post than modern saddles.

comment Does anyone have any special notes on buying pannier racks?
@DanielRHicks - cro-mo steel racks typically have higher weight limits and wiggle less under high loads. After 3 yrs of commuting on dirt roads my panniers wore over half way through my AL rack on my summer commuter. I will need to replace it soon as it will fail soon. On my winter/tourer my steel racks are going strong 8 yrs later with only cosmetic paint wear. Rust is really a non-issue with good Cro-mo. I live on the "wet" coast with some of the highest rain falls in the world (especially where I used to live for most of those 8 service yrs). Maybe after 20 years rust might be an issue.

comment What accommodations might be made for riding a frame 4'' too large?
Yes. I have been fitted professional a number of times. Last time was this year. And they even had lasers, no sharks though.

comment What accommodations might be made for riding a frame 4'' too large?
I think stand-over clearance is an unfounded myth. It should seem like a problem in theory, but rarely is in reality. Larger frames fit me better, leaving me with very little stand over clearance. It has never been an issue. When stopping I usually stay on the saddle and point a toe down (regardless of stand over). When jumping off, you usually tilt the bike to the side increasing the stand over.

comment Is there a standard equivalent for effort between distance and elevation?
@Kibbee I would be careful just because something is Ant+ doesn't mean it will record the power readings. The Cycleops power HR band sends both an HR and a power reading. My old edge 305 is ant+ but doesn't read power, same with most of the of the Garmin watches. I assume a non-cycling GPS may not look either. I have no idea about Ant+ phones. Software limitations yes, but limitations nonetheless.

comment Is there a standard equivalent for effort between distance and elevation?
Cycleops has a heart rate power meter that does a bunch of number crunching (I suspect some sort of statistical time series model) that gives decent average power over longer time periods (I.e., > 30 sec). It won't give an accurate peak power estimate and is affected by condition (e.g., fatigue, hydration levels affect HR), but as an inexpensive means of getting a ball park estimate of average power it is surprisingly good. Ran it beside a regular power meter and it was pleasantly surprised. Of course this needs an Ant+ bike computer ($$) to read it.

comment Disadvantages of Riding Larger Frame Sized Bike than Reccomended Frame Sized Bike
There is also the concept of a "fit window." Some can ride in a variety of positions without experiencing discomfort (or even notice much difference), while others have a very narrow set of preferences which they find comfortable.
