Problem Solvers Chainspy Chainguide

Problem Solvers offers two chain retention devices to keep an ever watchful eye on your chain while you are looking at what is in front of you. The Chainspy features composite "spies" and an alloy body. It is adjustable for different chainlines.

ChainSpy 1 will be mounted with an integrated 31.8 / 28.6 mm clamp (shims included).
ChainSpy 2 was designed specifically for use with Direct Mount frames or with the optionally available adapter (not included).
So you can use it on any build, from a commuter rig to the fattest of fat bikes.
