Tools

BMX race tools: kitting out the workshop and the race bag

A race bike strips down almost completely with a handful of keys, provided they are the right ones. Everything else — pulling a crank arm, replacing a bearing, truing a wheel — needs dedicated tools that a screwdriver and a hammer will not stand in for without damaging the part. Here is how a coherent kit breaks down.

Hex and Torx keys: the foundation

Almost every fastener on a BMX race bike is a hex socket head, with a few Torx bolts on calipers, rotors and some stems. One complete set covers most of the bike.

• Hex keys in 2, 2.5, 3, 4, 5, 6 and 8 mm
• Ball ends to start a bolt at an angle, with final tightening always done square
• Torx T10, T25 and T30 for rotor bolts and lever hardware
• Folding sets or long L-keys for leverage, plus 1/4" bits for a ratchet
• A compact multi-tool that lives permanently in the bag

The torque wrench, the tool that prevents breakages

On a bike built from aluminium and carbon, tightening by feel does as much damage as leaving a bolt loose. A low-range torque wrench, from a few N·m up to around 20, covers the stem, handlebars, seat clamp, levers and rotor bolts. Apply the figure printed by the part manufacturer, never the maximum the wrench allows, and work diagonally across a stem face plate. It is also what lets you hold a seat clamp securely without marking the tube.

Drivetrain tools

The drivetrain calls for specific tools depending on the standard fitted to your frame.

• Crank puller for square taper and cotterless chainsets
• Pin spanner and bottom bracket socket for Euro, Mid, Spanish or American BB
• Chain tool compatible with 1/8" and 3/32" chains
• Freewheel remover or chain whip, depending on a freewheel or cassette build
• Chain wear gauge, so the chain is replaced before the chainring suffers

Bearings, headsets and cup fitting

A bearing press and a bearing drift work as a pair: the first drives a hub or bottom bracket bearing squarely into its seat, the second removes it without scoring the bore. A headset press is needed for semi-integrated headsets, while an integrated headset simply drops in by hand. These tools save whole sets of bearings compared with the mallet method, and they pair well with our adaptors and reducers when you change standard.

Wheels, tyres and pressure

Add a spoke key in the correct size (3.2, 3.3 or 3.45 mm depending on the nipples), plastic tyre levers and a track pump with a readable gauge: in BMX Race, half a bar too much changes how the bike behaves through a berm. A quick check for lateral truth at the end of a session beats a full rebuild at the end of the season.

Workshop or trackside: two separate kits

At home you keep the work stand, the torque wrench, the pullers and the presses. In the race bag you carry only what is needed: multi-tool, 4, 5 and 6 mm keys, a 15 mm spanner for axles, a chain tool, a quick link, a few cable ties and a pump. That kit has to fit a side pocket and should never be raided between motos.

The BMX RACING advice

Tell us which frame, which bottom bracket standard and which hubs you run, and we will list only the tools you are genuinely missing rather than a full case you will half use. Being multi-brand, we compare tools on how they work, not on defending an in-house range. Dispatched within 24 to 72 hours, you can spread the cost over 2 or 3 payments available, and the rest of the range sits in our BMX accessories.
