Simplicity and straight-forward, female-specific tweaks to Santa Cruz's Superlight made the Juliana a favorite among dirt divas since '99. That was almost fifteen years ago, and now Juliana is being turned into its own division, with multiple models, and headed by none other than Juli Furtado. And, that original, successful formula soldiers on with modern updates as the Origin dressed here in the Premeiro complete mountain bike package.

Now, Small and Medium models ride on 29in wheels, reserving 26in ones for the X-Small version. Like the Segundo build, the Origin Premeiro is focused on value, but it steps up the performance game with a FOX Racing Shock up front and Shimano SLX components replacing Deore. You'll still find the Origin Premeiro equipped with Deore cranks, but the rear derailleur, shifters, cassette, and chain are now SLX.

The wheels consist of a Shimano M756 rear hub and Sram 716 front hub laced to WTB ST i19 rims with DT Swiss spokes. It also gets Deore disc brakes over the Segundo's Elixir 1's. While these components contribute to this Origin's impressive performance, the biggest contributing factor is its alloy, single pivot frame. Due to this, the Origin offers performance that can rival bikes costing twice as much -- with the reliability to keep it out of the shop and on the trail.

The light yet strong, hydroformed aluminum front and rear triangles are shaped and butted to place more material where it's needed. This ensures strength and stiffness for confident descending. But that strength isn't going to hamper your climb to the top, because of the hydroforming. any excess weight is eliminated to keep the Origin feathery. With big, 29in wheels, stiffness is paramount, that's why you'll find that the rear triangle has an asymmetric shape. This prevents flex and ensures suspension motion is directed to the rear shock and not into flexing the frame, which would cause it to dog trot around switchbacks or across rock gardens.

The Origin relies on Santa Cruz's proven suspension pivot location. It's placed slightly above and forward of the middle chainring, to offer responsive pedaling when seated. One drawback of single pivot designs has always been out-of-the-saddle sprinting, because the suspension will compress under rider loads -- losing energy to moving parts. Luckily, shock technology has mitigated that drawback. The FOX FLOAT CTD on this Origin has three distinct damping settings, and one of them is designed to counter those stand-up pedaling forces.

Aside from the Origin's women-specific geometry, it also gets a Juliana Segundo saddle along with a narrower and compact grip/bar combination that's optimized for smaller hands. The Juliana Origin Primeiro Complete Mountain Bike comes in sizes X-Small through Medium and two colors; Persimmon or Pearl White.

My new love....

I picked up mountain biking a couple years ago but it wasn't really until this past summer that I realized mountain biking=awesome. Cruising down the trail with the wind in my hair, the dirt flying up in my's a hard feeling to beat. While I really love to ride, I wouldn't consider myself an actual "mountain biker", and therefore couldn't give this bike a proper review if I tried. But I will say a few things, in case any of you other new-to-biking ladies are checking out Juliana bikes--I am in love with this bike. It feels like a Cadilac compared to the old Cannondale hardtail I was riding. I roll off rocks on those 29" wheels and the bike is like...."what rock?" I love the smaller grip on the handlebars, and the bike itself just fits me better than any other bike I've been on. I'm 5'4" and ride the Small.

My new love....
