"A solid stem that helps bring confidence to my novice mountain bike riding. ONE, has got a killer reputation, I run their carbon 50 mm rise bars on both my bikes as well as there pedals. I constantly search for new products they might introduce and will always be loyal to the brand. Quality company who cars what hits the market with the ONE brand on it."
"I had trouble making my new One Up Bar fit on the oem stem. Zero gap but not close enough tolerance. Solicited help from ONe Up and bought a new stem. Now everything is perfect, looks better than the original and I have a completely One Up Cockpit. THANKS!"

"Do you see some of the prices being charged for a MTB Stem--> Outrageous. Look, good stuff is never cheap but it also should not leave you thinking about selling your plasma. Get OneUp."
"Great product as always!"
"Love the center stripe"
"Really enjoy the fit of the 42mm stem, strikes a perfect balance! I appreciate the matte look and feel too."
Yes! This stem is a standard stem and is fully compatible with any bike set up that has 35mm diameter bars.
Stem length is personal preference. It is important to know that a shorter stem will have slightly more responsive steering and bring your riding position back and up. A longer stem will have slightly more controlled steering and will pull your riding position forward and down. If your comfortable with your current set up it is a good idea to match that as closely as possible. If you find your current set up is straining your lower back & arms, then consider trying a shorter stem. If you find your front end lacks control and the tire comes off the ground easily, then consider trying a longer stem.
The no gap-gap clamp design creates more consistent clamping force onto the handlebar. For installation, tighten the top stem face plate bolts so the faceplates contact the stem body and torque them to 6Nm, then tighten the lower stem bolts to 6Nm. Be sure to double check the torque on all stem bolts before riding.
No, you can run our Handlebars on any stem that has a 35mm clamp diameter.
You can yes, but you need the Knock block adaptor collar. The part number for that adaptor is: 545523.
