TOPEAK NINJA-C Chain Tool
Several times in the past, I have seen cyclists stuck sitting on a curb pounding their chain with a rock, an emergency fix that may or may not get you home. So, what about using a fully thought out chain tool that hides away inside the handlebars? The NINJA C is a really cool idea for a mini-sized but complete chain tool kit!
As the box states, The Ninja C chain tool stores inside your handlebar to keep the uncluttered lines of your bike, yet can be easily accessed when you need it. This 11-speed compatible chain tool includes a chain pin compartment, chain hook, and 4mm Allen wrench for easy operation.
Ultra-Compact design and implementation.
- CHAIN TOOL part = 3.4” x 0.9“ x 0.9” (8.6 x 2.3 x 2.3 cm)
- CHAIN HOOK part = 3.3” x 0.9“ x 0.9”s (8.5 x 2.3 x 2.3 cm)
First off, this is a very well thought out tool. When working on a chain, you need a tool to hold the chain and a separate tool to repair the links and/or pin.
Each of these parts is stored in its own “container” and placed inside each end of the handlebar. The only caveat is that the handlebar needs to have a minimum of a 70mm (2.76”) straight section handlebar end so the NINJA C can be slid in and locked into position.
EASE OF USE
If you have a problem with your chain and need a chain tool, this is the one you should get. One piece includes the chain tool/anvil, the other includes the chain hook and 4mm allen wrench which is used to turn the pin press.
When repairing the chain, the trick is to get as much slack as you can.
First, shift the rear derailleur to the smallest cog. Then, shift the front derailleur to the smallest chainring making sure that the chain still goes through the front derailleur cage and rear derailleur jockey wheels correctly.
Next, using the chain hook, grab each side of the chain as pictured, leaving enough slack links to use the pin press. If links are damaged, you can either try and straighten them out or just remove the damaged links with the press and included allen wrench. Grab a spare pin and press it in and snap it off with the press.
That’s it, simple to use and conveniently stored when not in use.
Pick one of these up today. It will pay for itself the first time you need it.
