Listed here are some key factors I’ve realized about sustaining my very own Shimano bike:
- All the time discuss with Shimano’s tips when adjusting or changing a sequence.
- Use a dependable technique just like the “big-big plus two” rule – the place you set the drivetrain in its largest cog and largest ring then add two hyperlinks – as a place to begin.
- Commonly verify your journey’s situation as a result of chains stretch over time which impacts their size.
By retaining these insights in thoughts I’ve managed smoother rides with fewer mechanical points down the road! Bear in mind: The appropriate match makes all distinction between simply driving a motorcycle and actually having fun with each pedal stroke in your trusty steed.
The best way to Measure Shimano Chain Size
