The One Multi-Tool You Need For Your Next Bikepacking Trip
20+ years testing gear in Colorado backcountry
Your Multi-Tool Is Your Insurance Policy
A quality multi-tool weighs a few ounces and fits in your pocket—but it can save a multi-day adventure when mechanical issues arise. As Park Tool's repair guides demonstrate, the key is carrying enough functionality to handle common repairs without excess weight or bulk.
Here's what actually matters when choosing a bikepacking multi-tool in 2025.

Essential Functions for Bikepacking
Must-have tools:
- Hex wrenches (2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm) - Cover 90% of bike bolts
- Torx T25 - Required for disc brake rotors and many modern stems
- Phillips screwdriver - Derailleur limit screws
- Chain tool - Critical for chain repairs, 12-speed compatible preferred
- Spoke wrench - Minor wheel truing
Nice-to-have:
- Torx T10, T30 - Some newer components
- 8mm hex - Crank bolts on some bikes
- Tire lever - Integrated levers save pack space
- Tubeless plug tool - Essential for tubeless riders
Skip these:
- Knife blades (use a dedicated knife if needed)
- Bottle openers (fun, not essential)
- Excessive spoke wrench sizes you'll never use
Featured Products
Crankbrothers M19
The M19 has earned its reputation as the gold standard for durable bike multi-tools. High-tensile steel bits resist stripping and rounding—a problem that plagues cheaper tools—while the 6061-T6 aluminum body handles years of abuse. All the essentials are here: hex wrenches from 2-8mm, Torx T25, Phillips and flathead, chain tool compatible with 8-12 speed drivetrains, and four spoke wrench sizes. The included nylon case protects the tool and prevents it from rattling in your pack. Yes, it's heavier than minimalist options at 209g. For reliability you can trust when repairs really matter, that weight is worth it. Lifetime warranty backs it up.
- High-tensile steel bits resist stripping
- 8-12 speed chain tool
- 6061-T6 aluminum body
- Four spoke wrench sizes
- Lifetime warranty
Lezyne Super V22
Lezyne's Super V22 packs 22 functions into a remarkably compact package—significantly lighter than the Crankbrothers despite more tools. Anti-corrosion vanadium bits pivot from the center, providing better leverage than side-mounted designs. The hex range (2-8mm), three Torx sizes (T10/T25/T30), chain breaker, and magnetic quick-link holder cover modern component needs. CNC-machined aluminum sides feel premium and resist damage. The pivot design does have a learning curve—new users sometimes struggle with bit selection—but once familiar, it's faster than traditional fold-out tools.
- 22 functions, lighter than M19
- Anti-corrosion vanadium bits
- Pivot design for better leverage
- Magnetic quick-link holder
- CNC-machined aluminum body
Topeak Mini PT30
For bikepackers who want every possible contingency covered, the Mini PT30's 30 functions leave nothing to chance. This is the most comprehensive tool we tested, including standard hex and Torx sets plus tubeless tire plug tools and a power link tool stored inside the body. The forged alloy construction handles serious torque without flexing. At 200g, it's not ultralight, but for multi-week expeditions where you can't resupply or find a bike shop, having every tool available provides genuine peace of mind. Includes a neoprene protective bag.
- 30 functions—most comprehensive
- Tubeless plug tools included
- Power link tool built-in
- Forged alloy body
- Neoprene bag included
PRO BIKE TOOL Compact Multi-Tool
The PRO BIKE TOOL packs 19 functions into a package that's both lighter and cheaper than premium options—without sacrificing essential functionality. All-metal construction (no plastic parts to break), chrome vanadium steel bits that resist stripping, and the same hex/Torx/chain tool coverage you get from tools costing twice as much. The compact 1.8 x 2.8 inch body disappears in a jersey pocket. For weekend warriors or bikepackers who stick to well-traveled routes with bailout options, this delivers excellent value. Won't last as long as premium tools under heavy use, but for occasional trail repairs, it's more than capable.
- 19 functions at budget price
- All-metal construction
- Chrome vanadium steel bits
- Compact 1.8 x 2.8 inch size
- 3.9 oz lightweight
How to Use Your Multi-Tool Effectively
Apply proper technique. Seat hex wrenches fully before applying torque—half-inserted bits round bolt heads. Use steady pressure rather than sudden force.
Know your torque specs. Modern carbon components have specific torque requirements. Consider carrying a small torque wrench for carbon bars, seatposts, and stems.
Practice at home first. Before hitting the trail, practice removing and reinstalling your cleats, adjusting your derailleur, and using the chain tool. Trailside isn't the time to learn.
Keep it accessible. Pack your multi-tool where you can reach it without unpacking everything—jersey pocket, top of frame bag, or handlebar bag.
The 5-Minute Pre-Ride Tool Validation
Before every multi-day trip, verify your tools actually work:
- Check each hex size against your bike. Can you access and turn every bolt that might need adjustment? Some recessed bolts need longer bits.
- Test the chain tool. Push a pin partway out on a practice chain. If you've never used it, you won't want to learn trailside.
- Verify spoke wrench fit. Modern wheels use various nipple sizes—make sure yours matches.
- Confirm T25 torque. Tighten and loosen your brake rotor bolts. This is the most common Torx use.
- Check for corrosion. Stiff pivots or rusty bits need cleaning or replacement before your trip.
Five minutes at home prevents frustrating discoveries 50 miles from anywhere.
Beyond the Multi-Tool
A multi-tool handles most issues, but consider these additions for remote bikepacking:
- Master link/quick link - Faster chain repair than using chain tool to rejoin
- Spare derailleur hanger - Frame-specific and impossible to repair trailside
- Duct tape - Wrapped around your pump or tool, endless uses
- Zip ties - Temporary fixes for many problems
- Small patch of tire boot - For sidewall cuts
FAQ
How many functions do I really need?
For most bikepackers, 15-20 functions covers everything you'll encounter. Tools with 25+ functions often include specialty bits you'll never use. Focus on the essentials—hex wrenches, Torx T25, chain tool—rather than function count.
Steel bits vs. aluminum—does it matter?
Absolutely. Steel bits (especially chrome vanadium or high-tensile steel) resist rounding and stripping. Aluminum bits are lighter but wear faster and can round bolt heads. For a tool you depend on, choose steel bits.
Should I carry a separate chain tool?
If your multi-tool has a quality chain tool compatible with your drivetrain (check 12-speed compatibility), it's usually sufficient. Standalone chain tools offer better leverage for stuck pins but add weight and complexity.
How do I maintain my multi-tool?
Wipe clean after wet rides, apply light oil to pivot points occasionally, and store dry. If bits become stiff, soak in penetrating oil and work the pivots until free. Replace the tool if bits become rounded or stripped.
What about tubeless-specific tools?
If you run tubeless tires, carry a plug kit (tire bacon) and an insertion tool. Some multi-tools like the Topeak PT30 include these; otherwise, a small standalone kit weighs almost nothing and can save long walks.

Keep your multi-tool in a frame bag where it's easily accessible without unpacking everything.
