▼HELP SECTION

Headset Type - the 1" size relates to the outside diameter of your fork's steerer column which should measure 25.4 mm, if it's 25.0 mm your forks should be French threaded. Although it's generally recommended to match threaded parts exactly, with headsets you can technically mix and match, unless you have French or the obscure old Raleigh threads, in which case you need to stick to that type. If you're replacing an old headset the thread may be stamped on there. Oversized 1 1/8" & 1 1/4" sizes are easily identifiable due to their size and the threads are all standard. Headclip headsets were made to fit fork steerers with 1" or the reduced 31/32" size steerers, as well as 1 1/8" versions for tandems.

Cup Size (OD) - the outside diameter of the cups, this must match the inside diameter of your frame's headtube closely for a good fit. For 1" headsets this should be around 30.2 mm unless you require a JIS headset which will be 30.0 mm.

Crown Race (ID) - the inside diameter of the crown race where it sits on the fork steerer, this needs to be close to the outside diameter of your fork steerer at the base to ensure a proper fit.

Stack Height - the overall height of the headset. To check the minimum stack height you require, measure the length of your frame’s head tube & subtract this from the length of the fork steerer column. You can always add spacers if you have a little too much steerer tube but you can't fit a headset with a greater stack height than the space you have available.

World War II - The Final Months
Format: Hardcover
The book takes you through the final months of World War II, focusing on eight key moments when the fighting finally came to an end. It’s not just a dry rundown of facts or battle maps — the authors do a great job of bringing the people involved to life, from famous leaders to everyday soldiers and civilians caught in the chaos. What I really liked was how the story moves around the globe, covering Europe, the Pacific, and beyond. It keeps the narrative fresh and exciting, giving a real sense of how the war unfolded on many fronts at once. Sometimes I had to pay close attention to keep up with all the locations and characters, but that only added to the feeling of being caught up in a fast-moving, gripping story rather than a history lesson. What stood out most was how it made me feel the human side of history—the fear, the relief, and the confusion as the war finally ended. It’s full of details, but it never felt boring or too technical.

The Fix
Format: Hardcover
An insightful and interesting book on how our country's first legislators try to make sense of the new and fairly short U.S. Constitution, which, being drafted by humans, was bound to be imperfect. A lack of clarity on some point might be due to the changeable nature of words themselves or to confusion or obscurity of thought by the authors. And, who were the authors? The men in the room who came up with the product or the various state conventions that approved the final product? Professor Gienapp writes well and with a fine grasp of his subject. He uses concrete examples to illustrate his main points. For example, Congressional debates over the constitutionality of a proposed federal bank, the ratification of Jay's Treaty, and even whether the Bill of Rights was to be incorporated into or simply added to the original document. Most people think of U.S. constitutional history in terms of its drafting and ratification and/or its later judicial interpretation by the Supreme Court. Here, Professor Gienapp focuses on the initial work of interpretation by the first few sessions of Congress. This book is essential reading for those interested in the U.S. Constitution and the internal architecture of our government. I think those who spend countless hours viewing frenetic talking heads say this or that about the constitutionality of some issue or another (or the nomination of a justice to the High Court) should throw their television set out the window and, instead, settle into a corner chair and calmly read this and other such thoughtful books. This one should win prizes.

Excellent Book
Format: Hardcover
Stanford University History Professor Gienapp has done an outstanding job of researching and writing this historical analysis of the interpretation of the American Constitution by America's first Congress. Professor Gienapp analyzes data primarily from Congress's problems interpreting the removable of executive officers, chartering a national bank and approval of the 1794 Treaty with Great Britain negotiated by Chief Justice John Jay, the "Jay Treaty." Gienapp shows in clear writing how Congress used records of the debates at the Constitutional Convention and State Ratification Conventions to resolve these constitutional issues. I highly recommend this book to anyone concerned with the interpretation of the American Constitution.
