Do it once and do it right.

In the early days of mountain biking, everyone ran a triple up front. Singlespeeds became pretty common in the late nineties, but it wasn’t until recently that geared bikes with one or two front rings became the norm. The SRAM GX group provides several options for each layout. The GX1 1400 GXP Crankset is SRAM’s most modern aluminum 1x crankset. The SRAM GX1 GXP Crankset works with a single up front and will only mount to a Truvativ GXP bottom bracket.

The GX crankset comes in several versions, including the value-oriented 1000 and the mid-range 1200, but the 1400 is the best there is. It's lighter than the others, thanks to hollow-forged crank arms, but it doesn't lose any stiffness to its solid-armed sisters. Mated to a forged aluminum spider, in fact, the GX is stiffer than most cranks on the market, even far more expensive competitors.

The SRAM GX 1x chainring uses X-SYNC technology. Each tooth’s thickness is CNC machined to work seamlessly with the chain’s inner and outer links to hold the chain in place in any terrain. With X-SYNC you never need a front derailleur, tensioner, or chain keeper to maintain perfect control over your chain.

I would like to convert my 2x10 drivetrain to a 1x. Can I use this crank or is it 11 speed compatible only?

hey Matthew, yes that will run with your 10 spd.

Would it work with bb/pf95? Please let me know, thanks.

Why would I choose a 170 over a 175 crank arm? I've been riding 175 forever but would there be some advantages to the 170? Thanks

Hey Craig,

There are a few factors to length of your crank arm. For one if your bike has a low bottom bracket you would want a shorter crank. The only reason is performance based. Most people think the longer the crank the more power. In reality longer cranks give you more torque. Torque and power are often confused, because the difference is subtle. Torque is a measurement of twisting force. Power is a rate of work – it’s the energy consumed during a unit of time. The more energy you put in, the faster the work is done, and the more power you measurably have. Longer cranks can give you more leverage (torque), but they can’t give you more energy with which to pedal!The reason you may consider a shorter crank is longer cranks can make it harder to sprint, as it’s harder to maintain leverage for as much of each revolution as with shorter cranks. In other words, it’s harder to pedal smoothly. They also straighten your knee at the bottom of the stroke and force it into your chest at the top, which can lead to pain and injury in knees and hips. Your lower back may also suffer. Its something that is personal to everyone, and dependent on the situation/bike discipline.

let me know if you have any questions. My contact info is below and i am happy to chat bikes anytime!
