SRAM introduced its 1x (pronounced “one-by,” as in, “1×11”) groupsets on mountain bikes in 2012. With
a single chainring in the front, and a 10- or 11-cog cassette with a wider range in the rear
, the 1x provided the same high and low gears as a double-ring drivetrain, while eliminating front shifting.
When should I replace my mountain bike drivetrain?
Mostly, mountain bike drivetrain can last
up to 15000km before it gets one replacement cycle
, drivetrain components vary in life span, the chain is the fastest worn part followed by cassette and chainrings, the chain should be replaced when it reaches 0.75% of a stretch when both cassette and chainrings should be …
What does 1×11 bike mean?
SRAM introduced its 1x (pronounced “one-by,” as in, “1×11”) groupsets on mountain bikes in 2012. With
a single chainring in the front, and a 10- or 11-cog cassette with a wider range in the rear

How do you convert 3x to 1x?
How do I convert my bike to 1?
Is 1×11 enough for MTB?
The choice of 1×11
works well for strong cyclists that enjoy rides or races with longer climbs with limited roads
(fire, dirt and asphalt.) These rides generally have technical singletrack descents that don’t require a lot of pedaling.
Which is better 2×11 or 1×11?
A 2×11 will, on the other hand, allow you to make quick, big gear changes.
The advantage of the 1×11 drive is its simplicity and reliability off-road
. Fewer elements leave us with better weight, and the narrow-wide chainrings and clutch make the problem of chain drop a thing of the past.
Are 1x bikes slower?
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.
How long do bike groupsets last?
A well-maintained groupset should last
a few thousand miles
before parts begin to wear. Disc or rim, 11, 12 or 13-speed, electric or mechanical; there are more options for groupsets than ever before, and the pros and cons of each can be overwhelming.
How do you replace a drivetrain on a mountain bike?
How long do MTB cassettes last?
A cassette, in most cases, can last for approximately
two to three chain replacements
if they are done at the right time.
How do you convert 3×8 to 1×8?
How do you convert triple chainring to single?
How do I change my mountain bike to single speed?
Do you need a special chainring for 1x?
While
not a necessity
, rings such as these can reduce the likelihood of dropping a chain. When used in conjunction with a rear derailleur with a clutch mechanism, such as Shimano’s Shadow Plus or SRAM’s Type 2, you should be able to run your 1x drivetrain without a chain guide. Chainring positioning in important.
Can you convert a 3x to a 1x?
Converting the front is relatively simple, just remove the three old ones and put a narrow wide chainring in the middle position
. You might need some BMX style narrow bolt and nut set to get it tight. But a clutch derailleur is kind of necessary in the back to keep the chain from bouncing of the front.
How do I set up 1x drivetrain?
How many teeth do you need for a single chainring?
Typically, on 1×11 systems where most systems use a 10-42 cassette in SRAM or 11-40 and 11-46 in Shimano, the chainring typically ranges from
28-36 teeth
in most cases.
Why do some mountain bikes only have 11 gears?
So why do mountain bikes have less gears? Mountain bikes have less gears for quite a few reasons, however the primary reasons being
less maintenance, lighter weight, and the need for only the quickest shifts when running into such a varied terrain
.
Why are bikes sold with only one gear in front?
Q: Why bikes are being sold with only one gear in front? These bikes are called 1X or OneBY drivelines. They have only a single chainring and a wider ratio rear cassette. Their advantage is that
they don’t have a front derailleur or shifter
.
Is a 1x drivetrain worth it?
The biggest advantage is probably how a 1x drivetrain
lets you focus on your ride, instead of constantly adjusting gears
. It’s also less likely that your chain will drop off the front since it’s fixed to one chain ring . All this does come at a price.
Is 2x faster than 1x?
Performance and Number of Gears. Some cyclists find that
2x drivetrains offer better performance than 1x drivetrains
. With a 2x drivetrain, you may be able to maintain a higher average speed or ride further without tiring out.
Is 1x better than 3X MTB?
For a beginner, there is no doubt that
a 1X drivetrain is the easiest to use
. If you want to go faster, you go up a gear, if you need to go slower, you go down. In comparison, using a 2X or 3X drivetrain takes a little more practice.
Why are 1x drivetrains more expensive?
Higher price – generally, a good quality 1x groupset costs more than a 2x, or 3x system of similar quality. Greater drivetrain mechanical losses –
because of more severe chain angle (cross-chaining) and fewer chainring teeth in some gear combinations
.
Can you cross chain on a 1x?
On a 1x drivetrain, if the single chainring was located in either of the positions of the large or small ring on a 2x or 3x drivetrain (to either side of the nominal chain-line), then
yes the chain would be ‘cross-chained’ when on either the largest or smallest rear sprocket
.
Why is 1x more expensive?
The 2x and 3x setups on cheaper bikes tend to be stamped steel (work fine, just cheaper to make) whereas the 1x rings tend to be machined aluminum.
The cassettes needed to give 1x a reasonable range for most riders are more expensive than 9 and 10 speed smaller range ones
. So, basically, it comes down to cost…
