When you’re new to bike servicing it’s easy to get overwhelmed by the sheer amount of specialist tools out there. The truth is, you only need a handful to get going, the rest can be quite bike-specific. These will cover most common repairs, help you learn the basics, and build your confidence before you splash out on anything more advanced.
Nearly everything on a modern bike is held together with hex bolts. A quality set with sizes from 1.5 mm up to 8 mm will see constant use. Long-handled keys with a “T” or “P” handle make life easier, but even a simple set will do the job. Bear in mind “ball-end” keys are good for some situations but don’t always bite as well as straight ended ones -and can wear your bolt heads quicker if over-used.
Changing tubes and tyres is the first real job most people tackle. Strong, non-metal tyre levers will save your knuckles and rims. They’re cheap, so it’s worth having two or three. If you find they are snapping/bending with your very tight tyres, consider using (carfefully!) metal levers.
Keeping your tyres at the right pressure is one of the easiest ways to avoid punctures and make your bike feel smoother and faster. A solid floor pump with a pressure gauge is a game changer compared to struggling with a mini-pump.
At some point you’ll need to remove or shorten a chain.
They may not be bike-specific, but you’ll need them for adjusting derailleur limit screws, balancing v-brakes, fitting accessories, and general tinkering. A sturdy set is essential. (avoid pozi-drive)
With these five tools you can handle the vast majority of beginner repairs: fixing flats, adjusting brakes and gears, swapping chains, tightening bolts. As you grow in confidence, you can slowly add more specialist tools.
Start small, learn as you go, and you’ll be surprised how much you can achieve with just these basics.
