Crankbrothers Multi Tool M 19 Matte Black Red - Compact Trail Tool

In this review of the Crankbrothers Multi Tool M 19 Matte Black Red the bottom line is simple: this is a compact, trail-ready multi-tool for cyclists who want a broad selection of high-quality tools in a slim package. The reviewer found the tool's precise fit and finish, plus its thoughtful side grips, make roadside adjustments and emergency repairs straightforward. At 89mm long and 175g, it balances carryability with a reassuringly solid build, making it a top pick for riders who prefer a single, durable tool in their pack rather than several loose wrenches and screwdrivers.

Key Features

• 19 integrated tools: Includes hex wrenches, screwdrivers, open wrenches and spoke wrenches, giving riders the range needed for common roadside repairs.
• Chain tool compatibility: The built-in chain tool handles 8 through 12 speed chains so you can fix a broken link on modern drivetrains.
• Ergonomic side grips: Textured side grips provide a secure handhold even when wearing gloves, reducing slip when turning stubborn bolts.
• Compact dimensions: At 89mm long and a slim profile, it packs easily into a saddle bag, pocket or pack without creating bulk.
• High tensile steel build: The precise fit and finish from durable steel mean the tool feels robust and performs consistently under load.
• Lifetime warranty: Backed by a lifetime warranty, it offers long-term value and reassurance for frequent riders.

Who It's For

The Crankbrothers M 19 is aimed at weekend mountain bikers, gravel riders and commuters who want a single, well-made multi-tool that covers the most common on-trail repairs. Its extensive tool selection and chain tool compatibility make it especially useful for riders who travel light but still want to be able to address drivetrain, wheel and cockpit issues without returning home.

Riders who need a featherweight kit for racing or ultralight bikepacking may look elsewhere if every gram counts, since some users note the weight feels slightly heavy compared with minimalist multi-tools. Also, if you require specialized workshop tools or torque-specific bits, a dedicated set is a better choice than an all-in-one trail tool.

Pros & Cons

Pros

• Comprehensive tool selection covers hex sizes, spoke wrenches, screwdrivers and a chain tool, reducing the need to carry extras.
• Solid build quality and precise fit make each tool feel reliable when tightening or adjusting on the trail.
• Ergonomic side grips improve handling with gloves and under wet or muddy conditions.

Cons

• At 175g some users will find it heavier than minimalist alternatives, so it is not the lightest option for weight-obsessed riders.
