Puncture Repair Kits

This contains the glue and patches that you may need to repair a flat tyre.

Some air will naturally escape from your tyre over time, so If your bike has not been used for a while it may not actually have a puncture. Try pumping up your tyre and leaving it for an hour to see if it maintains the same pressure.

After using the glue, please endure that the lid is replaced tightly as the glue quickly evaporates.

Freewheel / Cassette Removal Tool and Chain Whip

• 

  Cassette Removal/ Lockring Nut Tool

• 

  Chain Whip

These tools are for removing and refitting the rear sprockets from the rear wheel. A large adjustable spanner and grease are also useful.

The chain whip is compatible with the vast majority of cassettes and freewheels. There are a number of differently sized lockring nut tools, select the correct one for the wheel.

Freewheel vs Cassette

A freewheel will have the ratchet system (aka the clicky bit) built into it, whilst a cassette slides on to a separate ratchet system (the freehub). Many budget bicycles with 7 rear sprockets or less will be fitted with a freewheel, whilst other bikes will have a cassette.

Chain Breaker / Quick Link Chain Pliers

• 
• 

These tools are for “breaking” the chain open, which will enable you to remove your chain.

These days many new bikes come with a quick link or split link fitted as one of the links in the chain. Options:

• Quick link - compress quick link to open connection (ideally use chain pliers), can also be re-attached using the chain pliers.
• Split link - has a locking plate on one link, use needle nose pliers to slide off face plate, then link will come apart easily.
• No special link - use the chain breaker to press a pin out of any chain link to release it.

Chain Gauge

• 

Use this tool to check how worn your chain is. As you ride your bike, the pins in the chain wear down, causing your chain to stretch. Riding with a worn chain can wear down your sprockets, which can be costly to repair, so it is worth checking your chain wear regularly.

Wheel Truing Stand and Spoke Key

(Wheel Truing Stand on loan from Mike Haber)

• 
• 

This tool is to check and straighten your wheels. Straight wheels are important for bikes with rim brakes, as it prevents the wheel rubbing on your brakes as you ride. It also allows means you can set your brakes closer to your rims, allow for sharper braking.

Crescent Wrench

• 

Most budget bikes use a cup-and-cone ball bearing system on the bottom bracket (the axle between the peddles/front sprocket). As the bearings wear, or if the cones loosen, you will start to feel play in the bottom bracket. The crescent wrench can be used along with a spanner to access and service these bearings.

Bottom Bracket Cartridge Extractor

• 

Many mid range and older bikes will be fitted with a non-serviceable Bottom Bracket cartridge. When this is worn out, the whole unit will need replacing. This tool enables you to remove and re-fit this part.

Chainset Extractor

• 

The chainset (also known as crankset) is the collection of sprockets and the peddle arms (cranks) in the centre of the bike. Most bikes are fitted with a three piece chainset where each pedal arm side is pressed onto a centre axle (the bottom bracket spindle).

This tool enables the removal of the chainset. It pushes the chainset and pedal arms off the centre axle.

To install a chainset use a torque wrench and grease.

Workstand

• 

It's a bit wobbly, so make sure the quick releases are tight. It's not secure enough to work on pedals or bottom brackets, but it's great for using to set up your brakes and gears. Best to secure your bike by the seatpost, but if your cables aren't routed along the top tube you could turn the clamp and secure it there too.

This stand is fully adjustable and can hold your bike in various positions. By using this stand, you will be able to suspend your bike, enabling you to turn the peddles and wheels uninhibited. When using the stand whilst setting your gears and brakes, make sure the stand’s grip is not pressing against any of your bike’s cables.
