Cam size on supertopo
|
Hello there! |
|
The super topo rack suggestions for el cap routes are in inches, not BD cam sizes. A red #1 is not 1". You might need to find a ruler and measure your cams... |

But that's just math. To be clear, 2 ea -.3 inches to 3.5 inches means bring a double rack covering the entire range from approximately .75 cm to 9 cm. |

I have done Zodiac with only a new BD #4 & #5, as my big pieces. The only pitches you need them on is the nipple and the pitch off peanut. But, if I owned another #4 and #5 I would maybe bring them. The pitch off peanut is really run out if you don’t have a doubles. But you deficiently do not need a #6 on the climb. |

How ironic that you cannot discuss Supertopo topos on Supertopo. Not so souper after all? |

I'm pretty sure all the supertopo books have a reference page somewhere early in the book with cam sizes for different brands. They probably don't have the newer cams like Totems. Even better is https://cam-parison.com/, with which you can switch between metric and imperial. |

English = British Standard = Whitworth : U.S = U.S. Standard = inches : The rest of the world Metric. |

That's too funny, the U.S. & English imperial are not the same. |

Interestingly for surveying purposes the defined length of the inch varies depending on which state you are in, some use the US Survey inch and some the normal inch. |

The US standard was simply the ENGLISH standard but formally adopted at Independence and renamed so it was under US national control. The Imperial standard was an attempt by the Brits to make a little more sense of how things work (ie. Imperial gallon = 10 lbs of water) and was a reaction to the adoption of metric in the rest of Europe a few years prior. |

Get ahold of Woot!guy's and Putnam's guide. It has a great section on how different cams compare in size. No ruler necessary. |
|
No an inch in not an inch in all of them. There is NO inch in metric & try and find an inch wrench in whitworth. |

Which is exactly that there is NO other inch (unlike, say gallon and Imperial gallon, or nautical mile and statute mile.) An inch is 25.4mm in metric. Whitworth is a tool sizing standard and seems pretty irrelevant to the question at hand. Is it used for anything else? |

My experience with supertopo is that while intending to list gear sizes in inches, more often the actual size corresponds to the BD size. Meaning that if ST says 1” gear, what they really meant was a #1 Camelot and not 1 inch. |

Because you are confusing me more now!In fact you have to bring the entire rack on each pitch to be sure ? |
