Of single speeds and chain whips (sounds like leather vests or rubber underpants ought somehow to be involved, doesn't it?)
Despite the fact that I've climbed every steep hill in my riding area on my single-speed with the 18 tooth rear cog, I have aspired for some time to put on a 20- or possibly 22-tooth rear cog. I've got another single-speed with an 18-tooth cog which I will keep for when I'm feeling masochistic. Having never changed a cog before in my life (a major accomplishment last week was to replace a bottom bracket bearing in the same bike), I knew special tools (not the kind Congressmen like to photograph) would be involved. So I looked at the bike, looked at pictures on the Internet, and got lucky (no, not those pictures, and not that kind of lucky): I actually got the right freewheel tool the first time, without having to reorder anything. But then I came to terms with the fact that I needed a chain whip--another mysterious tool whose use I had never grasped until I needed one. Since the cog is self-tightening in riding use, and since it's the nature of the freewheel to spin freely the other direction, the chain whip holds the cog while you unscrew (using the freewheel tool) the ring that holds the cog in place. Chain whips are not that expensive, but I wanted the job done now, and the nearest shop that might sell me one is thirty miles away. So again to the Internet--where someone pointed out the not-until-then-at-least-not-to-me obvious, which is that you can wrap an old chain around the cog, clamp onto the old chain with Vise-Grips (or in my case, cheap Chinese locking plier knock-offs), and wallah, you have a serviceable chain whip. Which is the only useful bit of info in this post. The ring was on so tight that I had to use a lever on both the pliers and the wrench, but the job is done.

Of earthquakes and bikes
If there's a silver lining to the cloud of earthquakes and tsunamis in Japan, this might be it: more people are riding bikes there. What disaster will it take for us in this country to park our SUVs and make bike lanes?:

Naked bike ride
The headline proclaims "The 40 Best Pictures From The World Naked Bike Ride ‘09 (NSFW)." Personally, I'm skeptical. Looks like the choices were made in order to render the collection, if not not NSFW, then at least a little closer to being SFW than if it really had the best photos of naked and not-quite-naked people on bikes. You decide: http://www.buzzfeed.com/mjs538/the-40-best-pictures-from-the-world-naked-bike-rid

It's Alive! Or Ten Miles and a Six (er, er, What Comes After Six?)-Pack Later

Or, actually, It works!
A follow-up on the how-to-fix-a-flat-when-you-don't-have-anything-to-fix-a-flat-with stuff: Not only did the knot in the tube get me home the day before yesterday, but, two days later and no air added, it still has enough air to ride. This knot-in-the-leaky-tube thing is too cool to be true.

Stranded's (Not Very) Big Ride, or How To Fix a Flat When You Don't Have Anything To Fix a Flat With
I went out early this morning, about 9:00 (which is early for me, on a Saturday, anyway; normally at that time I'm still trying to figure out whose underwear I have on, if I happen to have any on. But that's a story for another time.) I aspired to another 50-miler, but after 20 miles or so, I had a flat. The back one, of course. No problem--like any well-prepared cyclist, I put in a new tube, after having checked the tire for whatever may have caused the puncture. I found nothing and assumed that whatever caused the puncture had come and gone. An erroneous conclusion, it turned out.
Five miles or so later, again came the sickening feeling of a mushy back tire. I pumped the tire up, went a quarter of a mile, pumped the tire up again, went another quarter of a mile, and realized all hope that the problem was a loose valve or some such easily fixed problem was in vain.
I didn't have another tube. I didn't have any patches. I didn't even have any of that disgusting slime stuff that never works, and anyhow, how do you get it into a Presta valve? Did I just claim I was a well-prepared cyclist?
The options didn't look attractive. Call for help? Unthinkable! Stuff the tire with grass? That's gotta take forever, and be a mushy ride into the bargain. Ride flat and ruin my tire, not to mention the wheel? No.
Once upon a time, I read an article in Bicycling magazine that said a last resort is to cut the tube in two at the site of the leak, tie a knot in both ends, air it up, and ride. At the time, it sounded kinda bogus--I mean, come on, a knot? How much air can that hold? And of course, I had no knife, but I did find the sliver of gravel that caused the leak by doing what I should have done the first time: I aired up the tube sans tire, spotted the leak, and knew exactly where to look in the tire. Sure enough, an almost microscopic bit of limestone, ready to ruin tubes I didn't have all day.
So I tied a very tight knot in the intact tube, with the leaky spot outside the loop, aired it up, and rode. Amazingly enough, it worked. A bit of a bumpy ride when the knot came round, but it sure beat the alternatives. I made it home, and managed to get 35 miles in. Not a bad ride.

50!, Part II

50!
Frozen thumbs. That's why I'm not a pro rider: at the first sign of thumb freeze, I head for home, where I can put the extreme lack of warmth in my hands to good use by wrapping them around a couple of bottles of Guinness. Oh, well, to the victors go the spoils; to the rest of us, beer.
However, inspired by the True Grit 50 in St. George, Utah, (http://www.mtbracenews.com/view_article.jsp?id=274), I'm planning to oil the chain on my Fuji 29er tomorrow, air up the tires, and see how close to the big five-oh I can get. I've done a couple of 30-35 mile rides on my single speed so far this spring, but there's a vicious little hill that I don't really want to tackle again without gears. The Fuji has three in front and nine in back, and does a blazing four miles an hour on the lowest gear combination. Meanwhile, for inspiration, some bits from MTB Racing News (URL above):
"Even the mud could not prevent Cannondale rider Alex Grant from throwing down an impressive race. Veteran of countless endurance races, Grant has proven himself in the never-ending rain and slop of La Ruta as well as the crippling cold of Leadville.
[Alex] Grant used his profound technical riding skills to establish an early lead in the jaded-rocks and demanding descents of the Zen trail then used his experience and determination to carry on in the demanding conditions.
Grant finished the slightly shortened course in just over 4 hours. By then things had gotten so bad that officials had to shut the course down. Only 11 riders were able to finish before the course closure.
After the race Grant said, "It was pretty bad. I was so cold by the end that I had to walk the final climb even though it's a road. I had to use the palm of my hand to push the shift levers. Both my thumbs were frozen and didn't work anymore."
Grant was followed by Chris Holley (Trek 29er)."
Fifty miles, just over four hours. That's almost 12.5 m.p.h. Not bad for pushing a heavy mountain bike through unholy weather.
