Bikes like to be looked after. They need to be looked after. Treat them well and they’ll pay you back in spades. Or miles. Or years. Even comfort. Certainly speed. Just like with a car the trick with bikes is to catch any problem before they happen. There are a lot of moving parts on a bike, and a lot of bad weather and potholes in the UK. Parts wear and corrode, even where you can’t see. Especially where you can’t see. So keep your bike clean, lubed and serviced. And when things do go wrong, and they will, get it worked on by someone who knows what they’re doing and has the proper tools to repair it. And who cares.
