Golden rule of cycle maintenance. Whenever possible always work on a clean bike. Problems easier to spot. And fix. Like the cracked sprocket on the rear wheel. Disappointing. Worn teeth I don’t mind. To be expected. But tiny fractures. No. Fortunately carrying a spare. And the requisite specialist tool.
Quickly discovering replacing the sprocket would require a chain whip. Common enough item. Struggling to conceive of any bike shop not having one. Which is why I don’t have one. Far too bulky. Instead, kindly lent one by Lisa at Agnes Water’s local hire shop. With a little help from second cousin Ken, repair soon effected.
