Assessment: One Up Cockpit – Bar, Stem, Grips & V3 Dropper


One Up Parts makes a few of my favourite cockpit components, I’ve been driving their carbon riser bar for years and it’s superb. Identical with their 2nd era dropper publish.

So, after they launched an alloy model of a handlebar that provides somewhat flex to melt blows, I used to be intrigued. And when their third gen dropper promised vital weight financial savings, I reached out. Right here’s the way it all got here collectively, beginning with precise weights.

One Up Cockpit – Precise Weights (and Particulars)

actual weights for one up mountain bike bar, stem and grips.

Precise weights for the entrance finish are:

  • Handlebar: 348g
  • Grips: 103g (pair)

The brand new One Up V3 dropper on the left is a 180mm journey publish and weighs 484g. That’s in comparison with the 150mm V2 dropper on the appropriate at 500g.

So, longer journey for much less weight…sure, please.

At a look it’s onerous to inform them aside save for graphics and the ridges on the collar. Learn our launch protection for all of the tech particulars, however principally it’s a brand new, lighter cartridge with fastened air strain that saves a lot of the weight.

I examined One Up’s Skinny Grips, that are 29mm in diameter and 138mm lengthy. Additionally they make Customary (30mm diameter, however with ridges on the underside, and Thick Grips (32-35mm diameter). All are available six colours plus Black, and all are $27/pair.

To be sincere, I’m unsure why I requested the Skinny Grips as I truly just like the design of the usual ones higher (and the 0.5mm further cushioning wouldn’t damage both, however these Skinny Grips are nice.

They’re grippy even within the moist (I at all times put on gloves, so no touch upon naked handed grip), and maybe as a testomony to the bar’s potential to take in the bumps, haven’t felt harsh…which is a praise for thinner grips, I can’t say that about each model. They’ve additionally held up nicely. The one potential knock is the ends are closed, so that they’re not appropriate with bar-end instruments with out some chopping.

The handlebar accomplishes its vertical flex by utilizing an ovalized form on the rise. It’s a bit thinner from the entrance, and a bit wider from the highest.

Having ridden each the carbon and the alloy model, and usually NOT being a fan of how harsh alloy bars are, I’m stunned at how a lot I like this bar. To be honest, it’s on a 170mm bike with massive tires, however it’s nonetheless instantly obvious that the bar is doing one thing to mitigate impacts and fatigue.

In case your (or your pockets’s) choice is alloy, One Up’s Aluminum Handlebar is a good choice at simply $90.

One Up’s Stem is available in 35mm (examined), 42mm, and 50mm lengths, all with 0º rise and just for 35mm handlebars. Bar clamp width is a stout 55mm, which makes it very sturdy however nonetheless leaves somewhat room for laptop mounts.

Stems aren’t probably the most thrilling product, however their important, and this one does what it ought to with out drama. It additionally appears to be like good, in all fairness mild, and can deal with every part from path to freeriding.

Trip Assessment

I principally summed up my emotions on the cockpit above. The handlebar is the standout, providing higher (any!) compliance than different alloy bars by a big margin. When you really feel somewhat roughed up after longer, extra aggressive rides however can’t pinpoint why, swap this (or their carbon) bar in and I guess you’ll like your bike so much higher.

As for the dropper publish, it’s nice, and it’s value giving a nod to the V2 model (proven above) as a result of it’s nonetheless obtainable and simply $185 (in comparison with $270 for V3). I ran this publish for fairly some time on some tough stuff, in various situations, and it’s nonetheless performing nicely.

However my Fezzari (now Ari) La Sal wanted extra drop, so the 180mm V3 changed it (beneath).

Not solely is the One Up V3 publish one of many lightest (if not the lightest normal dropper publish) in the marketplace, it additionally is available in an large vary of journey, from 90mm as much as 240mm! It may be adjusted by 20mm, and you’ll drop one other 10g with their titanium bolt package. It’s additionally tremendous simple to rebuild with primary instruments, and all components can be found

As for efficiency, it’s easy and actuates simply. Whilst you can’t alter the return velocity anymore, I’ve no complaints with its velocity or response. It goes down and up identical to I need. The one enchancment I’d make is to angle the entrance saddle rail clamp bolt ahead to make it simpler to regulate, however that’s a problem with nearly each seatpost on the market, not simply One Up.

One Up makes an incredible Dropper Submit Distant lever, too, which I used right here. The publish has a normal brake cable attachment level on the underside, so you may run principally any distant you need that clamps on the lever, however I’m a fan of matchy-matchy parts, and One Up’s has the additional benefit of a three-position mount that lets me fine-tune how far inboard it’s with out having to vary my brake lever’s place, and that works whether or not you pair it with its personal bar clamp or a Match Maker setup.

Remaining name? Get it. It’s mild, lengthy, and easy, which is every part I need out of a dropper publish.
