WITH 1x.
MICRO GUIDE TO 1x
There really couldn’t be a better time
to be a road cyclist. Or a backroads
gravel adventurer. Or a cyclocross racer.
Or a time-trial specialist. Because the
definition of “road” is changing.
And, thanks largely to our dedicated 1x
drivetrain philosophy that uses superwide-range 11-speed rear cogsets,
what’s possible with a single front
chainring is changing too. 1x drive
systems for drop-bar cyclists can
provide a simpler, quieter, and more
secure drivetrain solution to virtually
go anywhere. Not to mention an
incredible range of gears to tackle
an incredible range of terrain –
on the bike of your choice.
MICRO GUIDE TO 1x
SIMPLER. QUIETER.
MORE SECURE.
No kidding.
MICRO GUIDE TO 1x
Simplicity. Seems like a grand notion
thought up by some marketing
department. Especially when it comes
to the most complex system on a bicycle:
the drivetrain. Yet, our 1x drivetrain
philosophy simplifies rider inputs to one
shifter and one derailleur, for sequentially
easier or harder gear options. With one
ring up front, shifting on the back is simply
easier or harder. It means jumps in gears are
appropriate to the intended use of the bike,
and can be chosen to match each rider’s
ability. Questions about when it’s time to
switch to the big ring up front are gone.
The need to grab a couple more gears out
back after shifting the front is gone too.
Put simply, everyone benefits from
accessing all 11 gears from one hand.
MICRO GUIDE TO 1x
A quieter ride. Yes, we aren’t afraid to say
it – the quieter a bike is, the better it is.
And not just because it’s easier on riders’
ears. A quiet bike is a more efficient one.
No chain on front derailleur rub or no
chain slapping your beloved frame.
With a noticeably lower running sound,
our 1x drivetrains remove noise of excess,
giving you the chance to enjoy the sounds
of far more important things. Like the
sound of the air as you whisp by.
MICRO GUIDE TO 1x
A more secure chain. Less parts. A reason
as good as any to hug an engineer. Our
patented X-Sync™ chainrings have unique
tooth profiles that mate the inner profile
of the chain with corresponding sharp
and narrow chainring teeth, providing
unparalleled chain retention. Wet or dry.
On road or on race tracks.
FINDING YOUR
1x gear range.
MICRO GUIDE TO 1x
The intended use of your 1x drop-bar or flat-bar bike will have a drastic impact on the gearing selection. Closed course race bikes
like cyclocross or criterium benefit from using relatively tight gearing ranges. Conversely, gravel and city bikes are best suited for
our wide gear range cassettes because there’s no telling where the adventure might take you, and that’s exactly what 1x is for.
2x
1x
Taking an assessment of your ability further
strengthens your 1x gear choice. Gearing so you
don’t spin out for the finish line sprint is great so
long as you’re appropriately geared to get there.
And it can be smart to gear for the climbs,
especially if it helps you get to the summit first,
pedaling a wide range 1x bike. Remember, 1x gearing
ranges can be nearly identical to 2x, so you’re not
losing range – you’re gaining an optimized one.
Knowing the type of terrain you typically encounter can
also help to determine how wide you’d like to go out back.
And more importantly how to choose your front ring. As a
guideline, choose an appropriate climbing gear as your starting
point if hills and or mountains are on your regular route.

The difference in gear range between 1x and comparable 2x ranges
is surprisingly small. In fact, the small percentage lost in top or
bottom end range is more than made up for in the elimination
of crossover gears (gear combinations that are virtually the same
in the big and small chainrings) found on 2x.

ROLLERBEARINGCLUTCH™
X-SYNC™
PC-XX1 CHAIN
Dedicated 1x rear derailleurs deliver maximum
drivetrain stability — even through the most
punishing terrain. With Roller Bearing Clutch™
technology, derailleur bounce and chain slap
are eliminated without sacrificing precision.
X-SYNC™
1X™ CHAINRING
SRAM X-Sync™ 1x chainrings provide the highest level of
performance and durability. The SRAM X-Sync™ tall square
teeth edges engage the chain earlier than traditional
triangle shaped teeth. The sharp and narrow tooth profile,
as well as rounded chamfer edges, help manage a deflected
chain. To provide the best possible performance in muddy
conditions, the X-Sync™ chainrings have been designed with
mud-clearing recesses for the inner chain links and rollers.
XD DRIVER BODY™
XD is a driver body design that allows the use
of the SRAM 1x™ 10-42 Cassette and provides
an improved interface.
*SPECFIC WHEELS REQUIRED FOR XD DRIVER BODY.

CAGELOCK™
X-HORIZON™
Our X-HORIZON™ rear derailleur’s ‘straight parallelogram’
design limits all movement to the horizontal axis, which
makes ghost shifting impossible and also reduces shift force.
For quicker, more exact shifting, the large upper pulley offset
design maintains a constant chain gap across all gears.
With Cage Lock™ technology in the rear
derailleur, wheel removal and installation —
as well as chain installation — becomes faster
and simpler. Just push the cage forward to
create slack and lock it into place.
