OneUp Components Chainguide


When Jon from OneUp Components sent us their most recent Press Release touting their new chain guide it looked like it was well thought out but I initially wondered who it was for and how does it fit in with fat-bikes!

Well, with the evolution of more trail oriented fat-bike designs many of the new frames are including ISCG-05 mounts that OneUp’s Chainguide mounts to including the Salsa Bucksaw, RSD Mayor, several 11Nine bikes and the SOMA Battleaxe to name a few. That, coupled with the fact that while the new narrow/wide chainrings and clutch-type derailleurs are really good at keeping chains on, they still do come off the chainring from time to time.


Not mounted on a fat-bike here but use your imagination!


If you have a fat-bike and want to use a chain guide like this take a look at E-Thirteens chain guide adapter plate. Might be just the ticket!

What follows is the Press Release from OneUp. Read on to learn more!

Eliminate dropped chains forever and more than double your chainring life with the new OneUp Components Chainguide. At only 35g the OneUp guide weighs less than a sip of water, costs just $45 USD and saves you money in less than a season.

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.

World Class Test Pilots

To develop the ultimate chainguide OneUp worked closely with the Yeti Cycles EWS team throughout the product development. Jared Graves and Richie Rude have been racing multiple prototype iterations this season, testing the guide on the worlds toughest trails. This feedback enabled us to develop an ultra minimal chain retention system, good enough for even the worlds fastest riders.

Richie Rude “The new OneUp guide is great, it’s small, simple and is my choice for everyday riding”

Jared Graves “Its feather weight is awesome. Simple and very effective.”

Shaun Hughes (Yeti Cycles EWS Team Mechanic) “As a mechanic I’ve set up a lot of guides and I can say hands down it’s the easiest guide to install and setup out there.”

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 a OneUp guide means you now only have to replace your chainring when the driving faces have worn out, which typically doubles your usable chainring life. Buy less stuff – Work Less Ride More.

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!
