Solidly-built; BB spacers give good adjustability for chain-line; guide can be loosened to slide up and down to suit ring size. Bit of a faff to set up, but then all BB-mounted guides are. I've used this 38T and 32T single-ring setup and on balance it works brilliantly, and at this price it's a bargain.
2 things to note though:
1) It looks like it's designed for DH single-ring, so using a th
Chain device looks really nice, i ordered the bash ring type and i couldnt get the thing to work at all even when i had a local bike mechanic check it over and it still wouldnt hold the chain. So i had to buy the non bash guard type guides and it now works faultlessly.
Got one of these for my DH rig. piece of cake to set up, even using the supplied BB mount adaptor (which is usually a pain).
Yeah, it's a bit noisy. But it's on a DH rig and it keeps the chain locked in. And looks P.I.M.P! so who cares.
Awsome chainguide for 50 quid!!!
