Poor quality plastic head doesnt hold chain
by Peyer Ruszkowski
Small and adjustable guide but drops chains when nw chainring wears down and doesnt grip chain anymore. On my third plastic guide head now after others snapped off. Also plastic guide head lifts up and pivots on bolt dropping chain inside crank. Bolt also digs its way through soft plastic guide head and loosens guide head. Not a reliable chain device.

Easy to fit and adjust to the right chainring size. Another quality product from Oneup
Excellent value and performance
I've had this chain guide on my last two bikes and have never dropped a chain. Good price and lightweight too! The feature allowing you to move the top guide out of the way without removing the whole thing makes working on the bike easy.

I bought this as a little more back-up chain retention on my Trance and I should've done it ages ago.
Not much set up detail on the packet but the website has a dead simple video. Great price and keeps the chain on when things get rough.
Oneup chain guide
by David Santiago -
The chain guide is light and sturdy But trying to adjust the position of the guide on the start is kinda irritating because the plastic plates move a lot and don't stick on the dimples that it has. After minutes of adjusting it and tightening the bolts, I had it set and went for a ride. Through the sections that I know my chains would fall, It has held my chains and saved my time from putting em back. But one time I had my chain fall inward on the frame and this chain guide couldn't get the Chain back.. So try to play with the positioning of the chain guide to where it would perform 100%
Does its Job

Easy to setup, plenty of spacers to get the spacing right on chain line. Didn't even have to remove chainring although one of my ISCG tabs proved difficult from poor threading. Would recommend nice and light suits XC well helps in those more tech sections where you just want a bit more security. Ccmes with a second bolt for guide incase you need multiple spacers. Would have preferred Black Bolts over silver supplied :D
