  • From punishing to comfortable
Style: Xt-a823-140
I bought a 26in fat tire ebike. It was a torture machine because the handle bars could not be adjusted to a comfortable position. Putting this stem on made all the difference. Now my bars are high enough and back enough that I can ride without getting numb hands and aching elbows. The stem is good quality and effective and my bike rides went from misery to pleasure. ... show more

If you have a headlamp mount on handle bars you will have to change the way lamp bracket mounts

  • What I needed!
Style: Xt-a823-110
This is the 110 mm GEWAGE adjustable stem. I was kind of on the fence about getting an adjustable stem. But I am rather pleased. If anything I can use it to let me know how I want my stem set at what degree and order a fixed version. But all around great product.

  • Great stem. Weak bolts
Style: Xt-a823-140
Too bad I couldn't give this adjustable stem 5 stars. It seems very well designed and manufactured, is marked for easy installation and adjustments, looks super cool, and significantly improved my handlebar's stance. Minus 2 stars because one of the two bolts of the riser clamp snapped in half when I started to *loosen* it in order to add a ring one day after torquing it to spec. It's impossible to remove the half of the busted bolt left in the clamp without damaging its aluminum threads. Amazon shipped me a full item replacement. Can't afford a failure with this critical component, so I'm now going with my own steel bolts all around. ... show more
