ROCKBIKES TV presents a request to remove a crank from a bicycle where the screw holes on the crank have been stripped.
In our previous video, we showed how to remove a crank without using a crank remover, but this time, the screw holes for attaching the pedals are also stripped, so that method cannot be used.
This time, we will show you the process of removing such a difficult crank.
For tasks like this, which are difficult for individual users to handle, or if you have made a mistake midway through and cannot proceed with the work, we can help you as much as possible, although this is limited to those who can bring their bicycle to us.
The bullhorn handlebars introduced here are as follows:
SIXTH Components Horus Bullhorn Bar 31.8 x 480mm Φ22.2 Black
(Ideal type for converting a hybrid bike to bullhorn handlebars)

SIXTH Components Horus Bullhorn Bar 31.8 x 400mm Φ23.8 Black
(Type to be combined with single-speed or bullhorn control)

大変でしたけど、それも楽しみの一つです。
破棄される予定だったルイガノのロードバイクのフレームを譲り受けた時に同じケースを経験しました。
ペダル部分もクランク部分もねじ山がすっかりダメになっていました。
ベアリングプーラーもダメ、トーチで温めでもダメでした。
最終的にBB軸をグラインダーで切断しました。
クランク部分に切れ目を入れるのは思いつかなかったので、今回なるほどと思いました。
その後、BBは割合スムーズに外れてくれたのでフレームだけは守れ、友人の譲渡して乗ってもらっています。
現在、いわゆるルック車ですが、スクウェアテーパーBBが外れないフレームがあります。
インパクトを使ってもダメなので、諦めざるを得ないかと思いつつ、まだ破棄できずに所有してます。
ルック車とは言っても、なかなか諦められないものですね。
ロードから譲る時Sram Red左クランクの外し方を間違えて、キャップの六角とネジ山を潰しプーリー抜きで外し、今も魔改にAXS12速で運用してます。
趣味が昂じて定年後、ホームセンターでママチャリ修理やってます。
私には自転車屋さんはできないかな、とも思いました。こんなの相談されたら・・・。
ペダル側のネジもつぶれているので破壊に戸惑いはないですが、「活かしたい」とでも言われたら解はあるのか悩んでみました。
面白かったです。
※ほかのコメントにもありましたがシートポストの固着（金属フレーム）のサルベージ技術にも興味あります。

学生時代にボーリング場で働いていた時、工具と金具の組み合わせで即席治具にする創意工夫の大切さを教わり、故に西山さんの姿勢にも大いに共感致します
これからも実践的なノウハウ動画を楽しみにしています
