Oneup Components ISCG05 Chainguide

OneUp Chainguide

The OneUp Top chainguide does what chainguides do, but does it exceptionally well. At only 35g (less than a sip of water), why wouldn’t you want to eliminate dropped chains? As the waves of singlering-specific chainrings boast reliable chain retention, they aren’t 100% flawless. Dropped chains do happen, even with NW chainrings. The only real way to make dropped chains of the impossible, is by using a chainguide.

On another note, using the OneUp chainguide can potentially prolong the life of your chainring, as it limits the chains side-to-side movement reducing the NW tooth wear and totally preventing the chain from derailing. How’s that for ROI?

OneUp Chainguide FEATURES:

  • Install without removing your crank
  • Single tool install and adjustment (4mm hex)
  • Boost compatible
  • Oval Compatible
  • Stainless Steel hardware (Ever notice how much rust loves ISCG bolts?)
  • Includes 2 top guide pieces 1xBlack 1xGreen
  • Patent Pending adjustment system

SPECS:

  • Weight: 35g
  • Capacity: 26-38T
  • Chainline: 5.5mm adjustment
  • Mount: ISCG05
  • Material: 7075 aluminum, top guide glass reinforced thermoplastic

GUIDE SETUP INSTRUCTIONS

  • 1. Set chainring size tighten bolt to 3Nm
  • 2. Install backplate onto ISCG05 tabs
  • 3. Rotate backplate until flat is horizontal and torque bolts to 5Nm
  • 4. Install crankset with chain, use spacer shim block to measure clearance between back plate and chain
  • 5. Determine the corresponding number of shims as determined in step 4 or backplate spacer
  • 6. Assemble top guide with spacers and tighten bolt to 3Nm

Works like a charm
Easy set up if you are comfortable working on your bike and probably even if you are not.
So far it is doing its job really well. Quiet and unobtrusive.

Awesome chain guide
Simple but effective. Install couldn't be any easier it comes with a tool to let you know how many shims are needed. It works with my absolute oval chain ring. Also comes with a spare guide on top of that the price is pocket friendly what more can you ask for.

No more dropped chains...
Works great! Took me a few tries to fit it exactly how I wanted it but it's easy to adjust. Comes with a bunch of shims to get it just right for your chain line.

Will this one work on a trek top fuel (29) with an xt m800 1x crankarm. Currently with a 34 chainring
Enrique on Aug 29, 2016
BEST ANSWER: It should...
I have the same crank set with a 30 up front. The chain guide has different settings for your desired chain ring. The only thing I would check is the mounting points for the guide. If you have two threaded holes on the right of your bottom bracket, on top right and one bottom right, you're good to go.
Super easy install as well, you don't have to take anything off your bike.
Hop that helps...
