Crankbrothers F15 Multi-Tool — 15 Functions, 164g, Trail-Ready

The Crankbrothers F15 packs 15 essential tools into a slim, lightweight body weighing just 164g. Designed for riders who want genuine trail coverage without carrying unnecessary bulk, the F15 handles everything from bolt adjustments to a snapped chain link — all within a magnetic case that doubles as a leverage-extending handle.

What It Does

The F15 covers the fixes most likely to stop your ride:

Hex wrenches: 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm
Torx: T25
Screwdrivers: Phillips #2, Flat #1
Spoke wrenches: #0, #1, #2, #3
Chain tool: compatible with 8, 9, 10, 11, and 12-speed chains
Bottle opener

Technical Insight

The magnetic case keeps each tool indexed securely so nothing rattles loose mid-ride. When you need extra torque, the case acts as an extended handle — a practical detail that makes a real difference when tightening a stem bolt or bottom bracket component on the trail without a full workshop behind you. The slim profile sits comfortably in a jersey pocket or pack hip belt without creating an awkward lump.

Real-World Notes

The four spoke wrench sizes and 12-speed-compatible chain tool mean the F15 stays relevant to current MTB and eMTB builds rather than just covering legacy standards. At 164g, it is light enough to carry on every ride rather than leaving it at home to save weight. The T25 Torx is included as standard — increasingly important as more cockpit and drivetrain components move to Torx fasteners.

Why Torque Collective Stock This

The F15 covers nearly every trailside fix across both standard MTB and eMTB drivetrains, with spoke wrench coverage and chain tool compatibility that reflect what riders in our workshop are actually running today. It earns its place as a default carry tool for any rider heading away from the car park, and it is compact enough that there is no excuse to leave it behind. Crankbrothers have a strong track record in MTB accessories, and the F15 is a well-specified, no-nonsense addition to that range.
