I shortened the X9SL (or X10SL) chain to the proper length for my Ibis Mojo drivetrain, with my handy Park CT-3 chain tool. I always suggest you get a good shop strength chain tool, they make chain work extremely easy, and they don’t break. The pin removal was very smooth and easy, and the attachment of the chain on the bike was a breeze using their ‘MissingLink’.
Test bikes: Ibis Mojo and Moots Mooto-XZ 29er
Mojo -> XTR 11/34 & Sram 11/32 cassette, XTR & Race Face Next 22/32/44 cranks
Mooto-XZ -> 11/34 cassette, XTR cranks 22/32/44
The MissingLink is KMC’s proprietary connection system, much like SRAMS’s Powerlink system, which are both vastly easier to use than the Shimano replacement pins. Not sure who actually makes the system (suspect KMC), since they both look suspiciously close to each other? No tools are required to attach the chain together.
I have found the missing link between the higher ape and civilized man: It is we.
Missing Link Installation
Simply insert one half of the link in opposite holes, keep the chain un-tensioned.
1) Insert both halves of the MissingLink into the chain ends.
2) Press both halves of the MissingLink connector together.
3) Lock in place by pulling the chain apart.
4) Opening: press both plates together while sliding the chain ends towards each other.
KMC suggests that you always use a new MissingLink during installation, but I usually reuse them, unless the chain has gotten an inordinate amount of abuse or spent a long time on the drivetrain.
