As you would expect from any Lezyne product, the 11-Speed Chain Drive Tool is well designed and super durable to hold up to any amount of shop abuse. The chain tool features a CNC'd steel body that has sculpted contours to ergonomically fit your hands during use. The rolled threads of the tools spin effortlessly with driving a chain pin. At the end of the pin driver is an adjustable chain pin peening tool required for Campagnolo 11 speed chain assembly. At the ends of both chain driver and chain peening tool handles are small rubber ends which keep the handles in place and add some extra grip.
The top of the main handle sports 2 Mavic splined (3.22 road/3.45 MTB) and two standard (squared) spoke wrench. Included with the Chain Drive are a driver pin driver removal tool and one extra driver pin.
I am so sorry I bought this tool. Having changed chains for, literally, decades I thought I could handle the Campy 11 speed. But $200 for a Campy chain tool that I would use once every few years seemed a bit much so the $40 alternative seemed fine. It wasn't. It was impossible to get the pin to seat in the outer link plate and as much as i fiddled I just couldn't make it work, eventually bending the outer link plate so badly I had to resort to going to a good bile shop to undo my damage. Forget doing this yourself, just have a shop do it instead of wasting your time with this tool.
Pros: low cost
Cons: It doesn't work
