SRAM הכריזה שלא תייצר יותר מעבירים קדמיים והשיקה את המערכת החדשה שלה ה- Eagle מערכת 1X12 הילוכים עם קסטה 50 שיניים. ענננננננקקקקק!!!!!!!!
SRAM announced it will no longer produce front derailleurs. Today, it told us why.
SRAM Eagle ’12 Speed’ Drivetrain
Today, SRAM announced its latest 1x drive systems, Eagle XX1 and XO1. The systems, according to SRAM, are the first purpose-built 1x drivetrains, and achieves a massive gear range with a plate-size 50-tooth rear cog.
SRAM calls the setups the “highest-performing drivetrains to date,” and that they are “smoother, simpler, more durable and quieter than anything you’ve ever ridden.” Check out the video below for its marketing pitch.
10- to 50-tooth Cassette
There are few advancements in the Eagle drivetrains. Most notably, to obtain a gear range the rear cassette is exceptionally huge. It runs cogs of the following tooth count: 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, and 50.
It also squeezes 12 gears onto the rear cassette — an accomplishment possible due largely to other parts of the system like the narrow chain and rear derailleur (more to come).
These small-to-big cogs provide all the range most riders will need to climb super steep hills or roll fast on the flats and down logging roads, and, frankly, this has been happening for several years already.
