Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Just a bmx brake caliper. They have really long reach but many can't really handle much more than 2.2 or 2.3"

If it's a 20" wheel then probably 48 holes, but I see these brakes more often on 26" cruisers

Probably a Tektro 985 with a plastic cap over the acorn nut?

Does look like a schrader valve hole.
Fat bikes would have cantis or discs?

I’d still pick up a real precision one, but those seem to fall off trucks less.

Here is a bit of real sailing nerdism. Fast sailboats have no problem sailing faster than the true windspeed experienced by a stationary object, but they can't do it directly downwind. There's been lots and lots of debate, online and in yachty drinking places, about whether this is even physically possible. There was a consensus that if it could be done, it would involve a sail cart with a big-ass turbine to drive the wheels. Results have been ambiguous until now.

This video is long, boring, and heavy on the explanation of some pretty basic physics, but maybe worth skipping through for some. The basic concept to start with is that the turbine blades are not perpendicular to the wind, so the sailboat going directly downwind is not an analogy.

You would know this more than me: have you ever surfed down a wave DDW and achieved a speed faster than true wind? In other words, the wave is pushing the boat faster than the wind is pushing it.

Surfing doesn't count.

Well then, it's impossible for something to push something faster than the pusher is pushing the pushee.

True, but the question is can a clever machine use wind energy and momentum to go faster than that wind and the answer is yes.

I, for one, will now be able to sleep better at night due to this revelation.

First, I arrived home from my century on Wed and my wife informs me that the kitchen sink (a hands-free, motion detection jobber) isn't doing anything. I eventually get that problem fixed, but during the troubleshooting process, I had to turn the water off and on at the valves under the sink, and one of the valves decides that it's too old and has had enough of this crap, and it develops a slow leak. I address that next day, replacing both valves - done and done!

Nope - the day after that, I notice a drip in the basement. I check all of the connections under the sink, and they're all nice and dry. Go back to the basement to locate the drip - it's coming from the shut-off valve just under the kitchen, which I had to use to shut off the lines when I replaced the valves in the sink cabinet that failed when I was troubleshooting the faucet.

I just picked up the replacement valve for the basement, but if a leak develops at the water main valve, which is the next and only valve up the line from the one I'm now replacing, I'm going to be very not happy.
I have a strong dislike for those hands free faucets. Regarding the leak - do you have access to the street shutoff valve?

I cook a lot and, when doing things like handling raw chicken, the faucet has been awesome. This is the first trouble that it's given us, and I think it's because of some mineral build up in the hose, not a fault with the control box or anything.

No, no access to the street shut-off - I know where it is, but it's got a five-sided bolt securing it and it's MN, so the actual valve is pretty deep, to stay under the frost line, and you'd need a ~3 foot long thingie to reach and turn the valve. But I don't anticipate any trouble with my main.... (famous last words?)

I guess only if you need to replace the main shut off in the house. Our valve is under the frost line, but there is a piece that pops up above ground so what we can shut it off.

I had a fun ride Saturday with my buddy that owns Unified Beerworks and another of his friends that hasn't ridden all year. We did 75 from the brewery w/ 4500 climbing. About 40 of the 75 was on some sort of dirt or gravel. It rained pretty hard the night before, I had the Revolt ready to go (except for pedals) but really wanted to ride the R3 since the Giant has been bugging my knees lately (and it's nowhere near as fast as the R3 due to the fit). The first 3/4 of the ride was tough in the dirt, it got pretty soft and gnarly at points. I hit a deep soft spot going about 38 at one point and nearly dumped it. After about forty miles, the guy who hadn't ridden totally blew up and the ride ended up taking much longer than anticipated. All in all it was still fun, but I wish I'd brought the Revolt because I'd have needed to work a little harder to keep the same pace.

This weekend is Tour of the Battenkill, 75 miles, 5K+ feet of climbing with every significant climb on dirt. It has always been one of my favorites, I can't wait to do it again (it was cancelled last year). I'm considering riding to the start from home - that'll give me 103 on the day (wife is coming to meet me with the girls at the finish party).
