Which one fits you

Your situation Look at Why
You need a chain breaker on the trail Crankbrothers M 19 or Vibrelli V19 Both include a chain tool, with the M 19 specifying 8-12 speed compatibility.
You want the lightest possible tool Topeak Mini 9 At 3.24 oz, it’s the lightest here and still covers common hex sizes.
You prefer a ratchet for tight bolts ROCKBROS 14-in-1 Ratchet The ratchet wrench and bits can reach bolts in confined spaces.
You need tire levers included WOTOW 16-in-1 or ROCKBROS 14-in-1 Ratchet Both kits come with tire levers for flat repairs.

Practical tips

  • Check which hex sizes your bike’s bolts use and compare them with each tool’s list; Park Tool’s IB-2 is the only one here that starts at 1.5 mm.
  • If you want a chain tool, check its speed range: Crankbrothers lists 8 to 12 speed for the M 19, while Vibrelli calls its breaker universal without naming speeds.
  • Consider a tool with a carry case or neoprene bag to prevent rattling in your saddle bag.
  • A separate tire lever set is useful if your multi-tool doesn’t include them.

Which of these multi tools include a chain tool?

The Crankbrothers M 19 (8 to 12 speed) and the Vibrelli V19 (universal chain breaker). The other five do not list one.
