Last year I decided to switch from double ring to a single ring setup, and that forced me to quit my good old Blackspire Stinger and get a good chain guide.
After some market analysis the spotlight hit on the Straitline Silent Guide.
Out of the box we get the simplest thing to guide the chain. One backplate holding the two green sliders/guides, the bashguard, some spacers, instructions and a sticker. It not only feels light as it actually is!! Only 193gr (+20gr ISCG adapter)and the build quality is very good. One thing it doesn’t have is moving parts. Just motocross bike proven technology in a “keep it simple” way.
In my particular case I had to install an ISCG adapter with some modifications to fit my i-drive GT system, since Straitline only make ISCG fitting backplates. (After installing as the instructions manual shows, and I must say easy and fast!! it was ready to go down some trails.
As the name suggest it’s silent, with no moving parts, the chain passes on the sliders and makes none to little noise. It´s better than the chain rattle on my old Stinger.
During this time I´ve tried to test it on various types of terrain from speed bumpy descents to rock gardens and the chain never quit it´s place on the chainring. The backplate itself got some rocks at high speed and stayed stiff and aligned, so has the bashring. In muddy conditions the chain keeps rolling on the sliders normally. No hangs like on jockey wheel type guides.
With some use, the chain path cuts in the low slider, but as Straitline says it´s normal to happen. And if the sliders worn out, just buy new ones. In this half year riding with the Silent Guide in various conditions, (it felt like I made the right option) had no problems with it, just works flawlessly.
- little to no maintenance
- lack of BB fit (easily solved with the adapters)
Conclusion: The Straitline Silent Guide is a lightweight simple and effective chain guide that does it´s job, as the name says: silent. It´s a great solution for a single ring setup for enduro/all mountain bikes. Sliders have great life, backplate and bashring are stiff enough to eat rocks without complaining and it looks great on any crankset.
