Crankbrothers Multi Tool M 20 Matte Black - Compact Trailside Repair

Our review of the Crankbrothers Multi Tool M 20 Matte Black finds it to be a practical, all-in-one trailside companion for cyclists who need a robust kit without bulk. At 89mm long and 203g, the tool balances a slim profile with a surprisingly complete set of implements, including a chain tool compatible with 8 through 12-speed chains and an integrated tire plug tool whose plugs and storage case are included. This review focuses on real-world use: build quality, convenience on the trail, and whether the M 20 replaces a separate tool roll for everyday rides.

Key Features

• Compact size: At 89mm length the tool fits comfortably in a pocket or saddle bag for fast access during rides.
• Wide tool selection: Twenty high tensile steel tools cover hex wrenches, screwdrivers, Torx bits, spoke wrenches and an open 8mm wrench so most common adjustments are possible.
• Integrated chain tool: Chain tool supports 8/9/10/11/12 speed chains, letting riders perform chain pin repairs without carrying a separate unit.
• Tire plug system: The included tire plug tool, plugs and a mounting storage case make roadside puncture repairs faster and keep plugs organized.
• Durable construction: High tensile steel construction and Crankbrothers fit-and-finish give a tool that resists wear from repeated trail use.

Who It's For

The M 20 is aimed at mountain bikers and gravel riders who want a single compact tool that covers the majority of common trailside repairs, from spoke and rotor tweaks to chain and tire fixes. Its slim profile and included plug kit make it especially appealing to riders who prioritize a light, portable kit that still handles critical emergencies.

Riders who perform heavy shop work or need specialty workshop tools should look elsewhere, as the M 20 is designed for roadside fixes rather than full-scale mechanical overhaul. Those who insist on the absolute lightest weight may also prefer a pared-down multi-tool without the chain or plug kit.

Pros & Cons

Pros

• Comprehensive tool set covers most trailside needs, reducing the need for extra gear.
• Integrated tire plug tool with included plugs and mounting case makes puncture repair more convenient.
• Solid build quality and durable high tensile steel construction stand up to repeated use.

Cons

• At 203g some riders will find it heavier than minimal multi-tools, though many users still call the weight acceptable.
