Back in October 2015, after almost ten years loyal, four seasons’ service, Michael Stenning’s winter/training fixie’s chainstays were looking very scabby. Wet, salty stuff had snuck behind some superficial looking stone chip in the factory finish, causing it to bubble and blister as surface corrosion began to bite. My long suffering, though much loved, friend had more than earned its keep, so deserved a makeover.
