Crankbrothers Multi Tool M 20 Gold - Compact Trailside Repair Tool

Our review of the Crankbrothers Multi Tool M 20 Gold finds it to be a purposeful, compact companion for riders who want one durable device to handle most common trailside repairs. At 89mm and 203g it packs 20 high tensile steel tools into a slim profile while still including extras like a tire plug tool and storage case for plugs or quick links. The single biggest reason to buy is the combination of a full set of hex, Torx and spoke wrenches plus a chain tool that fits 8-12 speed chains, giving confident riders a true all-in-one roadside solution.

Key Features

• Comprehensive toolset: Includes hex wrenches, Torx, screwdrivers and an 8mm open wrench so riders can tackle most mechanical issues without carrying separate tools.
• Integrated chain tool: Works with 8/9/10/11/12 speed chains, allowing on-trail chain repairs and avoiding long walks back to the shop.
• Tire plug kit: The integrated tire plug tool and included plugs let you repair tubeless punctures quickly without extra bulky kits.
• Compact and lightweight: At 89mm length and 203g the slim-profile design fits in a pocket or saddle bag without adding significant bulk.
• Spoke and rotor tools: Built-in spoke wrenches and a rotor straightener help with wheel truing and brake rotor tweaks during rides.
• Lifetime warranty: Backed by a lifetime warranty for long-term reliability and peace of mind under regular use.

Who It's For

The Multi Tool M 20 Gold is best for mountain bikers and gravel riders who value a single, rugged device that covers a broad range of repairs from chain breaks to tubeless punctures. It suits riders who prefer carrying minimal gear but still want the ability to perform meaningful mechanical fixes on remote trails.

Riders who need a featherlight backup for XC racing or those who require a full workshop replacement on long tours should look elsewhere; while compact and capable, this tool balances versatility with moderate weight compared with ultra-minimal multi-tools.

Pros & Cons
