I've had the new OneUp Aluminum Handlebar and Stem on my downhill bike for a few weeks now. Since then I've put in 5 days at the Whistler bike and about 18,000 m of descending. It took a bit of time to get comfortable on this bar and stem as the 45 mm stem is 5 mm shorter than most downhill stems, and the 35 mm rise bar is taller than my previous bar. After moving some stem spacers around I got comfortable with the cockpit.
I like the sweep angles in the handlebar, and for my setup I liked the slightly shorter reach of the stem. While I had to lower my stem a bit to accommodate the higher rise bar, I do like the higher rise on my bike; it seems to give a greater variation in hand placement for a small change in the rotation of the bar in the stem.
I have soft office worker hands, so hand fatigue and arm pump is usually my biggest battle on a bike. The oval OneUp bar is one of the more compliant aluminum handlebars I've tried and it did seem to help with reducing hand fatigue. I thought I might not like the additional flex in the bars, but even with some hard landings and high load compressions I never noticed the bar flex in a negative way. Steering precision seemed unaffected, which is good! I ride carbon bars on my trail bike, and these do feel more like carbon bars than other stiffer aluminum bars I've tried before. Stem-wise, after 5 big days of riding the stem bolts have retained their torque perfectly. I haven't had these too long or crashed heavily with this combo yet, so I can't comment on durability.
So far I've enjoyed my time on the OneUp aluminum bar and DH stem. I think the combination looks fantastic, I like the bar angles, the bar made a difference in reducing hand fatigue, and they're reasonably priced. All in all I think the Oval Aluminum handlebar and downhill stem are great products from OneUp.
