Question: Can this be used with an 8 speed to make my mountain bike a 1x8 Drivetrain? Thanks
Document: A good looking chainring that does what it claims. I've been using this on my mountain bike for a few months now its performed flawlessly. Chain stays on. I do use a clutch xtr derailleur.
As part of my 1x10 conversion on my mountain bike, I needed to find a chainring with a low tooth count. The Race Face Narrow-Wide fit the bill perfectly - standard 104BCD, anodized red (my favorite color), and a reasonable price ($40 when I purchased it from Amazon).
I used this to convert my 3x9 stock setup on my canondale SL3 trail 29er, to a 1x10. I am so pleased!Some tips... Make sure your rear deraliur has a clutch, or you have some sort of mechanism to keep the chain from dismounting the front when there are lots of bumps. When installing, pay attention to the chain line and mount on the inside or the outside of your existing crank accordingly in order to prevent too much sideways movement and stress on the chain.
Just took my first ride on this chain ring and it felt great. I used it to convert to a 1 x 10 set up with my SLX shadow plus rear derailer and what it difference it made. Feels like a new bike. I wasn't sure about loosing my other cahin rings but I'm glad I did.
This is one of the few things that live up to the hype. If you're just starting MTB and you don't have your fitness up, this probably isn't for you. Enjoy your 3x or 2x setup for a while.I knocked off about 700 grams from my bike including the front derailleur, shifter, cables, housings and additional chain rings. I've had zero dropped chains in 300 miles of riding when used with an xt rear derailleur.
If you want to run a 1x setup, then this is a must have. I converted my 24 speed to a 1x8 with this chainring and had no chain drops even without a clutched rear derailieur. You will still get chain slap, however. I now run it with a Shimano Zee RD and a 10 speed cassette and it works like a charm with reduced chain slap.
This chainring is amazing. I've been struggling with dropped chains on my 2x10 drive train for my bike. I decided to try a 1x10 setup with this solo ring up front. After a few rides (and some super crazy bumpy technical ones) I've yet to drop a chain. This also with NO clutched rear derailleur. I'm just using my old SRAM X0 derailleur. Believe the hype. The narrow wide ring really does keep your chain on! Also, I'm running this with a Wippermann 10-speed chain.
If you are looking to convert your drivetrain to a 1x set-up, do not hesitate to get one of these.
Love the color, it matches to my frame. Super light and love the design. Will sure to recommend it. Thanks!
I have ridden a good many miles on this on two different drivetrain setups.On the first setup, 9sp with SRAM X0 long cage no clutch rear derailleur, it dropped the chain once when I fell off a log in a wierd way. Otherwise it performed flawlessly.
