【Overhaul】
Perhaps "disassembly and inspection" is an easy way to understand it.
It refers to the process of completely disassembling and inspecting mechanical items—such as watches, cameras, cars, and motorcycles—to ensure they continue to function without any issues.
In this post, I would like to introduce a bicycle that has undergone disassembly and rebuilding through an overhaul.
Originally, this was a road bike equipped with drop handlebars and gears. However, since there were parts that were unnecessary for the owner's use or didn't quite fit their body, we decided to go for a full overhaul and component swap.
Because it was quite an old bike (I checked, and it was a 70s Italian-made frame), it had many aging parts that were heavily worn, so we replaced a large number of them.
Also, since the owner was interested in track bikes, we decided to give that a try as well.
The roots of the Surly Cross Check’s versatility can be found in this bike, so we utilized that to its fullest.
As in our recent blog post, the single-speed gear ratio was carefully set with the riding environment in mind.
We changed the handlebar position from the deep forward-leaning posture of drop bars to the SimWorks Little Nick, converting it into a commuter setup designed for city use while still retaining a hint of its aggressive nature.
While this particular bike involved significant changes, sometimes all that is needed is a minimal replacement of parts like brakes, bar tape, or tires.
Of course, we often refresh bikes and return them to the owner without changing their riding position at all.
We want to keep riding the bikes we've spent years with for a long time to come.
Circles treasures that sentiment.
