Essential vintage bike tools for beginner mechanics

To fix your bike, you’ll need some basic bike tools and other items. Tou might already have some of them, while others are specific to cycling. These can form the foundation of your home tool kit, too, and include the following:

You will also need:

  • Toothbrush
  • Washing-up brush
  • Damp cloth
  • Bike lube (not WD-40)

Cleaning the gears

If you want your gears to change smoothly, it’s a good idea to give the chain and the cogs on the back wheel a good clean. You can start by taking off the back wheel. To do this, the first step is shifting the gear to the highest possible setting and removing the bike chain as far to the outside as it will go. Next, you can open the quick release to allow the brake pads to move further out. This is so they don’t interfere with the wheel removal process. Finally, it’s time to rotate the quick release. Pull the derailleur back while gently pushing the wheel forward to release it.

The next step is wetting the toothbrush and scrubbing the chain until all the visible dirt comes off. Then it’s time to give the cogs on the back wheel a scrub using the washing-up brush and the toothbrush. Once you’ve removed the gunky buildup, you can go round the cogs with a damp cloth and give them a thorough clean.

Putting the back wheel on can seem challenging to a complete beginner. A good starting point is placing the bike upside down and draping the run of the chain over the highest gear. That’s the smallest one on the gear cassette. The next step is pulling the wheel back into the dropouts while making sure the chain sits squarely between the chain- and seat-stays. Then it’s important to flip the quick-release level and move it to the rear end of the bike to stop it from interfering with the rider’s heel while riding. The final step is closing the level to get the brake pads closer to the rim.

Once the wheel is back on, you can put some lube on the chain. To do this, it works best to keep the bike upside down. Then slowly turn the pedals with your hand whilst applying a thin line of lube. You can stop once you have been around the chain once.

Adjusting the handlebars

To get the handlebars in the correct position, it’s best to use an Allen key. Start by selecting the right size of key and unscrewing the handlebars (righty tighty, lefty loosey!). After you have loosened the top screw with the Allen key, you can unscrew the base (you may need to use an adjustable spanner for this).

The handlebars should now be loose enough to adjust. Sitting on the bike will help you find the perfect position. Once you’re happy with it, it’s time to tighten the base and the top screw slowly – all the while making sure to maintain the correct handlebar position. At this point, it’s important to tighten both as much as you can.

Adjusting the saddle on a vintage bike

To get the best out of your bike, it’s a good idea to get the saddle to an optimum height. You’re aiming to get a 25-degree angle on the knee whilst your foot is on the pedal and the pedal is nearest the ground. The thing to remember is the perfect saddle height won’t necessarily be the most comfortable at first, though you’ll get used to it after a week or two.
To adjust the saddle, it’s best to loosen it using the adjustable spanner or the bike wrench. Once it’s loose, you can lower or raise it to the right height.

Making sure the brakes work

Before you finish off, it’s important to check the brakes for wear and tear – for example, if they look worn down, they may need replacing. It’s a good idea to compare the vintage break blocks to pictures online, or even ask the (Gumtree) seller to send you close-up photos of the break blocks so you can be sure you’re buying ones that will be compatible with your vintage bike.
We recommend testing the brakes thoroughly before you take the bike out for its maiden voyage. To do this, you can squeeze the brake lever, which should stop well before it touches the handlebars. If this is not the case and there is too much give, you can try adjusting them again.
