You get to hear one more "click."

I run D/A Triples on two bikes. On a third I switched it to a compact crank, D/A front derailleur and shifters, XTR rear derailleur and a 11X32 cassette. That gives me a high end about the same and a climbing ratio about the same. I like that too. With the Allegheny Mountains, Pittsburgh Hills,age,weight, motivation/declining testosterone, a bad knee, and such I need those kind of ratios on each end.

Price changing down is unlikely. Shimano is working very hard at keeping the supply low and in keeping resellers in line with MSRP. Our days of great sales could unfortunately be over. Europe is buying Shimano in large numbers, road biking is coming back here and supply is low. Oh well.

Here is a listing of some of our hills.

Pittsburgh Hills
Being located in the foothills of the Alleghenies, Pittsburgh has more hills than most metropolitan areas. That combined with road conditions that include no shoulders in many areas, cobblestone and brick roads, as well as potholes and road debris makes the area quite a challenge.
These are the 10 steepest grades in the city. The percentage expresses the steepness of the hill as the rise over run expressed as a percentage. A 0% grade is perfectly flat and a 100% grade is 45 degrees from the horizontal. The angle is the arctan of this number (37% = 20 degrees)

In general, Beechview has the steepest streets in the city. If you look at a topo map you'll see why. They force-fit a manhattan grid on Western PA terrain!

From Pgh Post-Gazette, Oct 5, 1984:

1. Canton Beechview 37%
2. Flowers Hazelwood 28%
3. East Woodford Carrick 27.6%
4. Cutler Northside 26%
5. Rialto (Pig Hill) Troy Hill 24%
6. Tesla Hazelwood 24%

5. Marion Forest Hills 19%

This next list is from the Pittsburgh Press on Jan 11, 1987 and was compiled by the Surveys Division and the Snow and Ice Control Program, Dept of Public Works. It is a sampling of streets and not the definitive list of steepest streets. The list has been re-arranged to be in order of steepness. It was originally in alphabetical order.

With all that, steepness is but one way to rate the hill. If you combine steepness with cobblestones or slick brick or bad repairs this can make a given hill more difficult than one that is steeper.
Most people overestimate steepness. The best way to measure a hill other than a topo map or surveying it is to use an inclinometer. Or some bicycle computers measure changes in elevation. The angle is then the arcsin of (change_in_elevation / distance).

In rating a hill there is also length to consider. For example, Cutler on the North Side is very steep and cobblestoned but is only a couple of hundred feet long. For a given power output, length as well as steepness must be considered. Thus a a short steep hill compared to a longer hill of the same elevation change might be less work.
