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

Don’t forget the hundreds of $ in cost for cutting tools that would deal with Ipe!

After that, throw away all the spent cutting tools you won’t be able to use again, don’t wrap it metal, use the ipe as your replacement crank arm, make it an “art fits function” piece.

This happened to me last year on a Ultegra 6800 crank. Not as catastrophic, but definite separation of the hollowshaft crank. Mileage was somewhere between 3,500 and 5,000. I was on vacation at the time with intent to cycle everyday so had a replacement sent next day air. There is a thread somewhere on it, but not worth looking up.
