MTB 31.8mm Aluminum


You have two Mountain Bike handlebars to choose from: Downhill for the most extreme riding and Trail for everyone else.

SKU: N/A Category:

Our Downhill bar is 800mm wide with 20mm of rise, 9° of backsweep, and 5° of upsweep. It’s built using 7050 Aluminum alloy for strength and long life. 65mm wide clamping area fits our Direct Mount stem, giving you the most torsional stiffness of any bar/stem combination. 31.8 center section is absolutely straight over a width of 90mm. The long straight section in the middle reduces stress concentrations, especially when using wide Direct Mount stems.

Identical in alloy and construction to our Downhill bar, our new Trail bar is 750mm wide with 20mm of rise, 8° of backsweep, and 5° of upsweep.. The clamping area is 50mm, allowing a different bend profile for a more compliant ride. The Trail bar gives you a light aluminum all-around bar for your Mountain Bike.

Bars are butted and tapered in many steps for optimal fatigue life. Ends of the bar are thickened from 1.4 to 1.6mm to resist damage from impacts and contact with the ground.

Bars are produced by advanced Hydraulic Press Forming to avoid the need for hand grinding. Almost all other bars are manually bent, and bends are ground to appear smooth. Hydraulic Press Forming ensures very consistent wall thickness and close tolerances, especially in tapered sections. This keeps weight low and fatigue life high.

Together with a Thomson stem, this is the best aluminum cockpit you can get. It’s the perfect addition to your Elite X4 Stem or Direct Mount Stem.



Why not a Carbon Fiber Downhill bar?

Downhill riding and racing involves the potential for fairly frequent, big crashes. Every time you crash on a carbon bar you may damage it, but you may not know. An aluminum bar will bend when it has been taken beyond safe limits. A bent bar should be retired.

What colors are available?

Downhill bars are available in black.

Can I use my aluminum bars on my dirt bike?

No. None of our bars are designed for use on anything with a motor.

Should I use friction paste on the stem and bar?

No. We have found that you should not use friction paste when both the stem and handlebar are aluminum.

Where are the aluminum bars made?

Our aluminum bars are proprietary designs made for us in Taiwan.
