I recently came across this ZTTO Portable Chain Link tool, which looks almost the same as the original Wolf Tooth Pack Pliers. Check out this link for the original article that describes this tool in detail.
As the ZTTO chain link tool is only 1/5 the cost of the original Wolf Tooth version, I decided to get one for my other bikes, and compare it with the original version.
At first glance, they look the same!
The aluminium centre bolt is available in many colours.
Here is the first difference. The Wolf Tooth version has a bolt and nut to tighten the two arms together, while the ZTTO version has a threaded hole on one arm, for the aluminium bolt to thread into.
Tip profile for opening or closing quick links look similar.
At the other end, the tire lever shape and Y-shaped slot for Presta valve cores are the same design.
The internal slots and magnet for storing extra quick links are the same as well, with the capacity to store 2 pairs of quick links.
View from the back, looks the same.
Side profiles look the same as well.
In summary, the ZTTO chain link tool only differs in the middle area, where the fastening method is different. Otherwise, functionally and appearance wise they are the same. Of course, we can see that the ZTTO version is a blatant copy of the Wolf Tooth version. However, at 1/5 the cost, the ZTTO version is a much more affordable version.
