Easy to install, low profile
The chain spy can be installed in minutes and is easily adjusted over a 1x chainring. The shims are robust and the arm linking the chain spy to the collar does not flex. This would fit over any size chainring I could add but other seatpost tubes may differ.

Works good
Works well, just carry a allen wrench because it can come loose every now and then. I have an E-bike that goes 44mph and this really helps keep the chain from coming off while riding. It has a single 52 thooth chainring. It has made the bike safer.

Liked it.
It works great. I've got it on a 1x9 Surly Troll and I've maxed out the adjustment. The shim wasn't thick enough to fit my seat tube, so I just made my own. Worked perfectly and easily.

PROS: Great Components, Versatile

BEST USES: Casual Trails, Single Track

Practical chainguide
not yet brought it to extreme trail (although warned by warranty) but this chain guide will do in most circumstances, good alternative and cheaper than the branded)
