I use a -6mm chainring on a 148boost to keep the chain line more straight in the climbing gears. Chain never falls out of gear when back pedaling even over bumps.
So glad Jenson puts these you tube videos out. I bought my Banshee from Jenson in the fall and they were great to deal with. Was a little worried about sizing but they removed all doubt once the bike arrived. Keep making these informative videos.
Thanks for the feedback, Mark! We will continue to try to make more content like this. Let us know if there are any topics you'd like to see covered. Cheers!

Hi my bike is an orbea rallon m10 2018 1x12 eagle . Just fitted a brand new hope evo crank so which one would I need? Think my wheelset is a 148x15 thru axle Cant believe there are numerous retainer rings.! Please reply really appreciate it. Thanks Jon
Hey Jon! If your cranks are Hope Evo cranks with the direct mount setup, this link should take you to the correct oval and round rings for your Boost frame. Cheers! www.jensonusa.com/Direct-Mount-Chainrings?DirectMountType=Hope&Offset=Boost
You're the only one who completely explained it! So, I took a chance and blew it then 😣 Bought a new cassette, chainring and chain. Lucked out and got the right offset (3mm), but I got a SRAM chainring and have Raceface NEXT cranks. So my center pattern will be wrong, right? 😩
This is extremely informative, and although I do not completley grasp the ideas and how it relates to my options in chainrings, it is appreciated. I have a zero offset Sram X01 chain ring in 32 tooth, that I like to replace with a 28 tooth. But for some reason, nobody in the aftermarket is selling zero offset. Assuming my chain line is perfectly centered in my existing cassette, would I get a 3mm or 6mm, or either, and which one would move the chain line more towards the bigger cassette cogs? Since I spin in the higher gears, and mash in the lower gears for climbing, I would want the chainline more towards the lower gear. Thanks for the video!
Very helpful and informative video. I have a problem with the chain dropping off the largest rearsprocket with any backwards rotation of the wheel, either by turning the crank or the bike rolling backwards. It is an obvious chain line issue. Current setup is a boost 148 axle with 3mm offset. I gather from this, by swapping to the 6mm offset, I will get a better less extreme chain line. Thanks
I have a salsa beargrease fatbike that need an upgrade from 30t to 32t chainring. The stock chainring has a stamp -4MM OFFSET. So which chaining do I need, 3mm or 6mm? Help... Little help...Thanks!😃
I have a canyon dude 8 fat bike with the Truvativ Stylo 6K Dub 30T direct mount with a 4mm offset. I want a 32 tooth and I cannot find a 4mm offset...only ones are available are 3mm or 6mm offset. I am not sure how to proceed.
I have a 152mm hub and i notice in 1st gear the chain rattles a bit (noise), it shifts fine and doesn't drop when pedalling backwards. But would it be ok to use a boost (3mm) chainring to try and eliminate that noise (and potentially a slightly better chainline). thanks
If my chainring is boost 3mm will it be stamped or embedded on it? I want to upgrade my current 30T chainring but I'm not sure of I need boost or not. I'm riding a 2019 Santa Cruz chameleon with a nx eagle crankset.
That chain ring should work just fine with your frame. However, Hope uses their own direct mount interface which may not be compatible with your current cranks. Please don't hesitate to reach put if you have any further questions or hit up one of our Gear Advisors (888-880-3811 ). Keep Pedaling!
Hi, im a regular customer on your online shop. Im looking for a bigger charing for my xtr crankset, mine has 4 holes, i want 42 teeth . do you think shimano has one? Thanks
Hey Rafael, it's likely that there is an option for your setup but we'd need a bit more info to make sure that we are getting the correct bolt pattern/spacing. Send our gear advisors a call or chat, and they can help hunt down the correct part. Keep Pedaling!
I have a cannondale 2012 trail 1 hardtail i will like to run a 1x12. Do i need a 6mm offset chainring to put a 12 speed cassette? Or the 6mm offset chainring is something different with the cassette? I will like to hace the best chainline posible. Thak you for your help

Hi i have giant yukon 1 fat bike with 197 axle in rear and i called sram they said i need - 4 offset n no one make 34 t direct mount chainring in that size any other option i can go right now my tore size is 4.5 27.5 thanks
How do i know what offset ring i have on my bike? Are there markings on the ring somewhere that tells you the offset? Or do i have to measure it myself? If so how do i do that?
I have a question. Can I use noneboost rear hub with 2x3mm adaptors for boost frame and correct the chainline with 3mmoffset front chainring on boost crankset?
Hmmm... We're not certain we are following your question. If you're talking about using Boost adapters for your hub, this offsets your non-Boost hub to make it have a Boost equivalent chain line. This means you'd want to use a Boost chainring. We hope that helps answer your question. Cheers!
if you use a 3mm offset on a non-boost frame, does that mean there will be rubbing on the chainring? what's the worst that can happen on this config with the 3mm difference?
While this won't cause any issue with your frame, it could cause poor shifting and drivetrain performance, and can cause premature wear to your drivetrain components. We'd recommend choosing the correctly offset ring.
Boost is 12x148, superboost is 12x157: it's the spacing of the hub. For instance, current Pivot frames use superboost 12x157 spacing so the rear triangle is wider at the dropouts than a boost frame. The offset of the chainring is determined by your frame spacing and chainline. Typically, boost is 3mm offset, superboost is 0mm offset and non-boost is 6mm offset. Look up your frame and/of hub spacing in a manufacturer chart to see which your frame is then choose the chainring offset based on that.
I need some help please. I have a cube MTB with eight gears behind. Most bike shops tell me that> I must to have 10-11 gears in the back to put a single disc arm. Any way...... can i doing my bicycle from 3×8 to 1×8? Or i have a problem? Congrats for your video. Thank you.
Hello! This is totally doable and we have done it many times successfully. Remember that you are reducing the overall range of your gear, so you will want to be certain that the range of available gears covers your ascending and descending needs. Also, clutch derailleurs are a big reason why 1x drivetrains work without dropping chains. When you get rid of the front derailleur, you're chain is more prone to falling off. Narrow/Wide chainrings and clutch derailleurs were created to solve for this. You can also use a chain guide. However, once you add up the new chainring, new bolts, and chain guide, it often starts to become a better value to purchase a modern take on the 1x9 drivetrain. Box Components has done this very thing. The have a wide range cassette, 9 speed clutch derailleur and nice shifter for a solid value. You'll still need a chainring, but this will give you the best performance for the money. Give our Gear Advisor Pros a call at 951-234-7554 and they can help get you dialed with the best bang for your buck for whichever route is best for you. Cheers!
Looking at the specs on that bike, it looks like it comes with a 10-speed setup with a 30t front chainring and an 11-46 cassette. There are a few ways to change up your drivetrain, but the easiest and cheapest is to swap to a bigger front chainring. This will reduce the low (climbing) gearing. That bike has a Prowheel C10Y-NW crank. We looked that up and it appears to have a 104mm BCD (bolt center diameter) for mounting up a new ring. We really like these Race Face chainrings due to their great performance, good price and fantastic color options. Hope that helps! www.jensonusa.com/Race-Face-104-BCD-Narrow-Wide-Chainring
@@jensonusabicycles thanks, I love the yellow one. my concern is the clearance of the crankring from the frame. Which is the biggest size that will clear?
Do I have to get the boost rear and front, cassette and crank? Is the sram dub direct mount a boost? Or is there a Sram dub direct mount non boost? do you need a spacer for direct mount? Thanks
I think either your frame is designed for boost, or it's not? I don't think you can put boost axels and stuff on a frame that wasn't designed to be boost compatible?
I decided to put a non boost (6mm) chainring on my boost frame for a better chainline on the big cog. It works but clearance is very tight maybe 2mm from ring to frame. Is this an issue?
If you look up the specs on the bike, from either the web site or maybe find a manual online, you can probably figure out if the bike is boost compatible or not. Also the model year would be a good indicator too. Like anything after 2016 is probably 1st gen boost (3mm) offset, according to the video.
I swear the bike industry with ever changing so called standards ruins the bike industry for the average consumer. They are literally reinventing the wheel every few years making what ever you were told was the latest and greatest something obsolete.
Hey Khairul, the best way for us to be sure we're getting you a fully compatible chainring is to hit up our Gear Advisor Pros. They'll be able to ask you some questions that will ensure they have all the right info to make sure everything works together. 1 tip with oval rings; most people will size down from the round ring that they usually run. So you would likely look for a 28t unless you felt like you were spinning out with your current 30t. www.jensonusa.com/company/gear-advisors
