2 X 10 Mountain Bike Drivetrain

I get asked about swapping a bike over to 1x from a bunch of different people who own bikes with a buuuuunch of different drivetrain configurations and with the recent video on upgrading my.

2 x 10 mountain bike drivetrain. The 1x drivetrain has all but killed the multi chainring setup at least on mountain bikes. They are usually referred to by the smallest and largest cogs to provide an indication of the total range e g. This is something i have been doing for a long time now on all of my mountain bikes so let s get into the nuts and bolts of what you gain and lose by converting to a 2 9 setup on your sled. So to understand why and determine if 1x actually is a better system we re putting it to the.

Two common choices among mountain bike riders are the 1x11 and the 2x10. Curious how switching from a 2 10 drivetrain to a 1 11 group like xx1 will affect your gearing. With the introduction of 2 10 components from sram and shimano there has been increasing talk amongst mountain bikers about the benefits of converting their 3 9 drivetrain to a 2 9 drivetrain. 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.

Your choice will have a direct effect on how you and your bike perform. Ok sure having to shift a front derailleur is a first world problem but once you go 1 by you never go back or something like that. The chart above click to enlarge shows how the different xx1 chainrings with that oversized 11 speed cassette stack up helping you choose the right front chainring s for your riding. Mountain bike cassettes can be found in 7 through 12 speed versions.

Sram lists a 1 10 conversion kit on their website which made the project seem simple. Horses gears for courses terrain. I use 2 x 10 right now but am going try 1 x 10 modifying an xt 11 36 to 11 40 with a hope t rex 40 ring out back with a 34 tooth oval n w absolute black chain ring. Thanks to scott at switchback bikes wonder no more.

So back to xtr di2 with 2 11 with 34 22 rings and 9 44 cassette gives me over 750. The one or two refers to the number of chainrings on the front of the drivetrain while the second number 10 or 11 refers to the number of cogs on the cassette in the rear of the drivetrain. So i had to see if i could convert my sram x0 2 10 drivetrain to 1 10. 500 is not enough if you are not a b grader and ride 25 grades.
