The Deviate Chain Guide is the result of over a year's R&D and testing in Scotland and the Alps by both our engineering team and ambassadors.
Eliminating dropped chains is at the core of any chain guide, but Deviate’s design also tackles key challenges including durability, reliability, drag and even noise.
- Adjustability : Works with chain ring sizes from 30T to 36T
- Durability : Grease port is fitted to protect the bearings (as seen on Deviate’s Highlander and Claymore frames)
- Reliability : Designed with long rides & racing in mind. Reduce maintenance with built in grease ports, twin-lip wiper seals and pre-mounted bash guard
- Efficiency : Jockey-wheel system improves guide efficiency by reducing the risk of the chain seizing
- Noise-reduction : Soft rubber included to reduce noise
- Drag-reduction : The grease ports not only provide longevity but also reduce drag on the ups
- Protection : Comes complete with pre-mounted and adjustable bash guard
- Compatibility : ISCG 05 lower only chain guide. Works with a range of suspension platforms (not just high pivot) and oval chain rings
- Part Replacement : No need to replace the entire guide, the bash guard and jockey wheel can be easily replaced
Installation : Install without removing your crank
- Chainline : 52mm (55mm with 3mm spacers and longer screws)
- Material : Injection moulded nylon & CNC-machined Aluminum backplate
- Capacity : 30-36T
- Weight : 109g
- Mount : ISCG 05 lower only
Whilst not tested outside of the Deviate bike range, it should be fully compatible with most other mountain bike frames.
The installation is streamlined thanks to the adjustable design, relying on just two bolts to attach and no need to remove cranks:
- Using a 6mm Allen key remove the Chain Guide Bolt from the Chain Guide. Skip this step if you are able to unlink and re-link your chain or are yet to link a new chain
- Remove the Jockey-wheel from the Chain Guide housing, place the Chain Guide over the chain (as shown) and then re-insert the Jockey-wheel into the Chain Guide housing. If you are able to unlink and re-link your chain or are yet to link a new chain, pass the chain through the Chain Guide, above the jockey-wheel, and (re)link your chain
- Using a 6mm Allen key, re-insert the Chain Guide Bolt into the Chain Guide now that the chain runs through the guide ensuring the Jockey-wheel is aligned for the bolt to pass through. Whilst doing this, place the bash guard plate into the desired position (see step 4) and thread the Chain Guide. Bolt into the female thread of the T-nut
- Set the Bash Guard by sliding it left or right until it is in the desired position and tighten the Chain Guide Bolt to 4nm of torque by threading it into the T-nut
- Align the Bash Guard with the Bash Guard mounting points on the bike and move the Bash Guard clockwise or anti-clockwise to find the optimum position. Using a 4mm Allen key, thread the Chain Guide CSK Bolts into the female Bash Guard threads on the frame
- Test and tweak the Bash Guard and Chain Guide positioning using the sliders on the Bash Guard until you’ve found the optimum setting
- Can I run an oval or elliptical chainring with my chainguide?
- Yes if inside the 30-36T chain ring
- Do I still need a chainguide if Im running a narrow-wide ring and clutch derailleur?
- We would still recommend running a chain guide/bash guard for maximum protection and chain tensioning
- What is ISCG? Is there more than one ISCG standard?

Nice bit of kit, super easy to fit. It does increase chain noise in large gears so if you pedal a lot in granny gear it may be a bit annoying.
Really well made and designed. It does make a little more noise under pedalling but once you're descending it's so much more quiet.
I'd definitely buy one again and certainly wouldn't want to run the bike without it now I've used it!
Nice piece of kit easy to set up works sweet. Only downside the bolts supplied were to long for blind holes.
I do like the quality of deviate stuff
No more fiddling with other guides. This goes directly to claymore and works great. Though I had to put spacers to get correct chainline but maybe its spider and crank thing. Chain noise is more but maybe time will decrease that. It is also possible to move lower guide and maybe keeping guide on bike park days.
