Do I really need a chain guide?
Why You Should Run a Chain Guide. Mounting a chain guide on your mountain bike gives you an extra sense of security, hopefully ensuring that you won’t ever drop your chain. When you are flying through rough sections of trail, the chain will jump up and down and can sometimes work its way off the chainring.

How do you choose a chainline?
Chainline is the distance between the centerline of your frame and the average centerline of your chainring(s). For 1X this is easy – If the center of your chainring teeth is 49mm from the centerline of your frame then your chainline is 49mm. It gets slightly more difficult if you have multiple front chainrings.

What is the ideal chainline?
The word “chainline” refers to how straight the chain runs between the front and rear sprockets. Ideally, both sprockets should be in the same plane, so that there is no sideward motion or stress to the chain. This constitutes “perfect chainline”.
Is 1x drivetrain better than 3X?
Gear range of different drivetrains:

In the above example of bikes with common drivetrains, the 1X bikes top out at 47 to 48KPH in their highest gear, while a 2X or 3X bike will offer 15-20% more speed, topping out at 56 to 57KPH.
Can I use front derailleur as chain guide?
Enthusiast. Sure, you can run a derailleur as a guide. No worries. FWIW, I built up a 1×9 this summer, and my first thought was to just run a derailleur as a guide, because I happened to have an extra derailleur laying around.
Do you need a chain guide for 1×10?
You don’t need a chain guide because it’s a hardtail. The N/W chainring and clutch RD should do the trick.
Is 52mm chainline boost?
Shimano states 52mm to be boost and 142 dedicated, 55mm apparently boost dedicated giving better chain line. Looks like there isn’t a 55mm “better” boost for XTR. I found 55mm to be much better for boost with a 5010 frame.
Do you need boost spacing for 12 speed?
If you are running 12 speed, the clearances are so small between chain and cassette that you MUST run a boost spaced chainring with a boost spaced bike. If you don’t, the chain will “tick” on the next bigger cog when in the smallest 2-3 cogs on the cassette.
Is 1x Good for uphill?
It comes down to the type of rider you are and the terrain you will be riding most. 2x gives you a wider range and makes it easier to tackle steep climbs, while the 1x is much easier to operate and is less prone to chain drops.
Is 1x OK for road?
Yes, of course it’s possible for 1x to feel ok on the road if the terrain is flat enough; many rides and races have been ridden with an 11-25 cassette and never shifting from the 53, but that doesn’t make the inner ring redundant.
Do I need a chain guide on a road bike?
Chain guides are needed primarily by bicycles running 1x drivetrains. Models with double or triple chainrings do not require a chain guide because the front derailleur plays the same role when adjusted properly. Single-speed bicycles don’t need a chain guide either.
How do you stop a chain slap?

Do narrow wide chainrings need special chain?
Condensed Answer: Narrow-wide chainrings are fairly thin since they’re designed for multi-speed chains. Meanwhile, single-speed chains are wider than multi-speed chains and the narrow-wide ring will have no problem fitting between the plates. Thus, a single-speed chain can operate with a narrow-wide chainring.
What chainline is super boost?
Super Boost Plus 157 uses the exis ng chain-line developed for DH bikes but uses standard trailbike BB widths and crank combinaYons to take 29” and Plus bike performance to the next level.
Is 142 a boost?
Boost 148mm
148 x12 or Boost spacing is the current standard for MTB rear hubs. It offers a significant improvement in stiffness and strength compared to 142mm. Chris King, Hope, Industry Nine, DT Swiss and Onyx offer all of their hubs in this spacing.
Are oval chainrings better?
As a direct consequence, Oval rings enhance a cyclist’s ability to spin with a smoother power delivery and feel much easier on legs while climbing. Meaning you will go faster and get less tired. You will actually feel your pedal stroke to be more “round” with an Oval chainring than with a round chainring.
Is 1x enough for road?
Is 1×10 enough for MTB?
1×10 is not good, range is too small, difference in weight isn’t worth it and it’s not that cheap especially if you add things to make it better like chainguide, clutch mech, nw ring and larger cassette cog. If you want to go 1x, I’d definitely recommend SRAM because it’s the only good way to get proper range.
Is 2x faster than 1x?
The 1X system is 0.9% slower than a 2X drivetrain which results in a 3 minute and 50 second time penalty over 100km. When travelling at faster speeds, the higher wind drag negates the additional frictional losses resulting in the 1X drivetrain being 0.3% slower.
Is chain slap normal?
It is completely normal. There are several things you can do, the simplest one is putting a slap guard around your drive side chain stay. You could use an old tube or a purposely made foam guard.
What causes chain slap?
Re: Chain slap causes? One cause (and not necessarily yours) is a sticky freehub so that when you coast the freehub is turning the cassette and de-tensioning the chain. You can check this by spinning the rear wheel and observing if the freehub wants to turn the pedals. You could always fit a chain stay protector.
Do you need a chain guide for 1×10 narrow wide?
Registered. You don’t need a chain guide because it’s a hardtail. The N/W chainring and clutch RD should do the trick.
How do I know if my chainring is narrow wide?

Is Super Boost better than boost?
Once purchased and activated, Super Boost promises the chance to be seen by up to 100 times more potential matches. By comparison, Boost only increases profile views by up to 10 times.
Whats the difference between boost and super boost?
A few small frame manufacturers felt that Boost was a stop gap to solving for wheel stiffness and chain line. As a result they encouraged the adoption of yet another new standard. “Super Boost” was a rear standard that was wider still at 157mm.
