What is SRAM Dual Drive?
What is SRAM Dual Drive?
SRAM’s DualDrive is a unique drivetrain that combines a three-speed internal-gear hub with an external cassette and derailleur. The result is a wide-range of gears in a clean, one handed control system.
What is 2x drivetrain?
2x drivetrains have smaller steps between gears than 1x drivetrains. In other words, the difference from one gear to the next is smaller. This is possible because 2x and 3x drivetrains have more gears within the gear range than 1x drivetrains. This way, the percentage change from one gear to the next can be lower.
What does SRAM mean on a bike?
Scott, Ray, and Sam
SRAM LLC is a privately owned bicycle component manufacturer based in Chicago, Illinois, United States, founded in 1987. SRAM is an acronym comprising the names of its founders, Scott, Ray, and Sam, (where Ray is the middle name of the company’s first CEO, Stan Day).
Which is faster 1x or 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.
Are SRAM and Shimano the same?
The key difference between SRAM and Shimano groupsets is the shifting actuation – the distance between shifts relative to the lever index. Shimano’s 1:1 ratio means the cable and derailleur move further during each shift. SRAM works on the tighter tolerance of a 2:1 ratio.
What is a 1x drivetrain?
The simplicity and effectiveness of a 1x (pronounced “one-by”) drivetrain, which refers to a single front chainring with multiple sprockets and a rear derailleur, has many people converting their multi-chainring setups.
What are the different SRAM road groupsets?
While SRAM and its house brands, Zipp and Quarq, produce components and gear for all disciplines including mountain bikers and commuters, this buyer’s guide will focus on the company’s road groupsets which can be divided into four technologies: eTap AXS, eTap, 22 and 1x.

Why does the new SRAM chain have a flat top?
To make room for that extra cog at the back, the gear spacing has once again got smaller resulting in a narrower chain. SRAM has bolstered the chain by introducing a new flat-top construction, which is claimed to add strength and shift performance.

What is a SRAM grip shifter?
SRAM is an acronym for Scott, Ray and Sam, the three founders of the American-based firm that started out producing grip shifters for road bikes in 1987. While these shifters didn’t sell particularly well, SRAM adapted the technology for off-road use and it became an instant hit among the mountain biking fraternity.
How many teeth are in a SRAM cassette?
SRAM is offering three one-piece cassettes; 10-26t, 10-28t, and 10-33t which combine with 1x and 2x chainrings — the jumps between the 2x chainrings are 13-teeth in every combo. Even if you opt for a smaller chainring at the front, the 12-speed cassette offers an extensive spread of ratios thanks to the 10-tooth cog.
