Alright, back on topic. The Roval CLX 64 is one of the most aero rims right know. The closest I could find is the Nextie 28mmx60mm, so I ordered a set in 18/24. I think I'll use Dura Ace 9000 hubs. Not sure on the spokes yet. I like the 17mm inner width.

True. The full formula shouldn't be ignored because that is how Paul Dirac discovered antimatter (or was led to the idea).

He won't answer that so obviously we are dealing with Kletus the Silencer Kid's Mk. 1 ears, hopefully calibrated.

Point taken

i have to say, there is no sublimation going on when liquid goes to a gas. there is from solid to a gas, or a liquid to a plasma. i know physics rather well folks, my testing is showing that the blasts are louder with water in the can. in my test, some small amounts of water in blast chamber and th...

Only the surface area will sublimate. The phase transition will more than offset the volume change. Any minimal increase in "wet" medium will be offset by the dramatic decrease in Combustion gas volume/pressure/temp.--- wtf? No. https://en.wikipedia.org/wiki/Evaporation#Factors_influencin...

wtf? No.

Don't put in so much. I've never seen a test where wet was louder.

10 acres is a nice size. I recall you posting pics of a house on an island. Do you still have that one?

My area's population density is about 20/square mile. Kinda hard to convince the telephone company to run me a T1 line 5 miles.

That's because you live in the northeast where people are packed like sardines.

We're still running phone lines to country places out here in the wild west.

So now, instead of getting a flat, you'll get a flat and your bike covered in sealant.

So my $2 thrift store helmets protect me just as well as my expensive ones. Good to know. Now is the season for sitting mindlessly on the trainer. Try Zwift.com. I still have good enough weather for outside rides but on days where it sucks, I ride Zwift. We recommend bandwidth of 3Mbs or higher, wi...

Specialized says that using a fatter tire on the rear is fast. http://specialized.desk.com/customer/portal/questions/14417655-tire-size-s-works-turbo-24-or-26mm That is because they test them at 40 kph and they are factoring in drag. At 30 kph I bet 26/26 is fastest. Except, the slower you go the m...

Friction Facts has data for dirty cyclocross chains.

Also I found that Specialized tires are 30% cheaper from French retailers.

So olive oil is sub optimal. That saves me from having to test it.

Another road tire test. How is your German? http://bikeboard.at/Board/Die-schnellst ... 2-th217501

Any tyre review is rubbish if it doesn't have experimental data. Compare these two from BikeRadar: Kenda Kountach: http://www.bikeradar.com/road/gear/category/components/tyres/road/product/review-kenda-kountach-tyre-48235/ They describe it as a race clincher and "a fast rolling tyre". S wo...

Ok thanks for the report. The bead to bead width of my Challenge 27mm Parigi Roubaix is 70mm, but the btb of the Specialized Turbo 28mm is only 62mm. On a 15mm iw rim the Challenge is 28mm wide and it is 31mm wide on a 17mm iw rim. The Turbo is 28.4mm wide on a 17mm iw rim so it must be undersized l...

I wonder if the olive oil is quieter than the wax based ones.

I have never tried to mountain bike without retention pedals. If you like it, I'll give it a try in a few months when I start mountain biking again.

I found a test of handlebar widths in a wind tunnel.

If it wasn't for tubeless mountain bike tires, I wouldn't even be riding mountain bikes. I used to use 40psi just to avoid pinch flats. With 20 psi it is like adding 20mm of suspension front and rear. Undamped though.

That was easy.

That's an impressive helmet effort. Are you going to keep all the ones you like? I just buy my mountain helmets at the thrift store for $2. If it doesn't have a visor I add a cycling cap. These look a lot more aero than my Sidi Genius 5. I could make an aero fairing to cover the laces and attach it ...

You bought FIVE helmets?
