OneUp Components made their name with 42 tooth add on rings for 10 speed cogsets. Taking that momentum, they’re introducing the their new Chainguide claimed to eliminate dropped chains and increase chainring life. At only 35g this ultralight comonent costs just $45 USD.

Q&A with OneUp’s Jon Hadfield

Why do I need a guide and a Narrow Wide Chainring?
Narrow Wide rings are awesome, but they’re not perfect and every once in a while you can drop a chain riding. On a social ride this means getting dropped by your friends. But when racing an Enduro a dropped chain can cost you the podium, which is why almost every EWS pro runs both a chainguide and narrow wide chainring.

How can I double my chainring life?
As a Narrow Wide ring wears, over time the teeth thin and loose their chain retention ability, leading to more dropped chains. The OneUp guide extends the life of a Narrow Wide ring by limiting the chain’s side-to-side movement reducing tooth wear and totally preventing the chain from derailing. Installing aOneUp guide means you now only have to replace your chainring when the driving faces have worn out, which typically doubles your usable chainring life.

Narrow/Wide chainrings don't retain as well when their worn but the chainguide extends their useable life.

What about Stainless Steel Narrow Wide Rings?
Some ring manufacturers are starting to use stainless steel to provide longer wearing no drop rings. The system weight and cost of our Aluminum narrow wide ring paired with our chainguide is similar to that of a stainless steel ring. But even with a brand new stainless steel chainring you can still drop a chain, especially in muddy conditions, after a big compression or with a worn derailleur clutch.


The install is quick and easy with no need to remove your cranks. Perfect chainline setup is a breeze using the chainline shims which space the top guide rather than the back plate. This means no guess work or messing around with annoying hard to reach ISCG washers. The adjustable design fits chainrings from 26 – 38T and is oval and boost compatible. Our Patent Pending adjustment system makes us the cleanest and lightest fully compatible ISCG05 top guide on the market – Never drop a chain again!

    Humm. I like.
    Cost is good
    Weight is good
    Mounting looks good, but I dont have ISCG tabs. So, it won’t work for me.

    Now if I could only get one one anodized red!

    I installed this two weeks ago and it’s awesome. My drivetrain was worn enough that I was dropping chains on rooty downhills more frequently. The oneup chain guide stopped the dropped chains and with the added bonus of quieting the chain slap. It’s light and cheap and works really well so far.
