Product information "Double Checker Chain & rotor wear checker"

The Dynamic Double Checker precisely measures chain wear and brake disc thickness. Suitable for 7-13-speed chains, with rotor check, integrated chain hook and robust aluminium design.

Double Checker - precise tool for chains and rotor

The Double Checker combines several essential workshop functions in one compact precision tool for everyday cycling. The three-point design determines the actual pin wear of the chain particularly accurately and therefore delivers more reliable results than conventional measuring methods. Marked test slots for SRAM, Shimano, Campagnolo, Magura and Hope brake discs make it easier to quickly check the rotor strength directly on the bike. Made of anodised aluminium with integrated guidelines, ruler and clever chain hook, the tool supports efficient and safe working.


Features - Dynamic Double Checker

  • Precise 2-in-1 tool for measuring chain wear and rotor strength - compatible with all 7-13-speed chains including SRAM Flattop, Shimano and Campagnolo.
  • Innovative three-point design measures actual pin wear and delivers significantly more accurate results than conventional chain gauges.
  • Brand-specific rotor slots for SRAM, Shimano, Campagnolo, Magura and Hope allow quick and precise control of brake disc thickness.
  • Made from lightweight, anodised aluminium with integrated chain hook and ruler - for fast, safe work and a longer service life for your components.

Compatibility

  • Chains: 7-13-speed, including SRAM Flattop, Shimano and Campagnolo
  • Rotor: SRAM, Shimano, Campagnolo, Magura and Hope

Material

  • Anodised aluminium

Scope of delivery

  • 1 x Dynamic Double Checker Chain & rotor wear checker

How to use

Chain check

  1. Insert point 1 and 2 into the chain (Pointing the pins down)
  2. Lift the chain between points 1 and 2 to create tension
  3. Press point 3 down into the chain
  4. Read the wear indicator:

< 0.5 % - Chain in good condition

0.5 % - Replace 11/12/13-speed chains

0.75 % - replace 7/8/9/10-speed chains

Rotor check

  1. Pick the right slot for your rotor
  2. If your rotor fits into the brand-specific slot, it needs to be replaced. When in doubt, always verify the minimum thickness on the rotor itself.

Chain hook

  1. Insert the two hooks, ensuring no tension on the chain in between the hooks for stable, mess-free chain mounting and dismounting.
  2. Close or open the missing link on your chain.
