As a small woman (I’m 4’11” and 108 lbs.), I sometimes forget that the world wasn’t built for people like me.



Subir a las encimeras para alcanzar los armarios, o necesitar un asiento elevador para estacionar en paralelo, se han vuelto la norma. Y aunque olvido lo pequeño que soy, a menudo noto que ciertas tareas parecen mucho más fáciles para otras personas. Tomemos el ciclismo de montaña, por ejemplo. Siempre asumí que mi incapacidad para cambiar de frenar con dos dedos a uno se debía a la falta de habilidad, no a manos pequeñas con alcance limitado. O cuando me encontraba esforzándome más que mis amigos en las subidas, pensaba que el problema debía ser mi condición física, no el tamaño y peso relativo de mi bicicleta.

Pero luego aprendí algo que cambió para siempre la forma en que pensaba sobre las bicicletas. ¡NO están diseñadas para personas de mi tamaño! No, ni siquiera las pequeñas. La mayoría de las bicicletas (y más importante aún, sus componentes) están diseñadas y probadas para hombres de tamaño promedio. Esto planteó la pregunta: si pudiera construir una bicicleta de montaña ultra pequeña pero altamente capaz, ¿mejoraría mi experiencia? Más importante aún, ¿haría el ciclismo de montaña más divertido? Y así comenzó la búsqueda de mi ajuste perfecto.

Viviendo en el Bosque Nacional Pisgah, sabía que necesitaba un cuadro que pudiera rendir bien tanto en subidas prolongadas como en descensos técnicos y empinados. También sabía que quería cambiar de ruedas de 29 a 27.5 pulgadas. Lo sé, lo sé, esta elección es algo controvertida. Mi objetivo era reducir la altura de paso de mi bicicleta, lo que me facilitaría mucho manejarla, incluso al simplemente subir y bajar de la bicicleta. Esta elección solo me dejó con un par de opciones de cuadro, siendo el de menor peso el Rocky Mountain Element.

The Rocky Mountain Element is marketed as a cross-country bike designed to strike the perfect balance between climbing ability and downhill capability. Despite its XC label, the bike has grown in travel in recent years, now sporting 120mm of rear travel and 130mm up front. In addition to the fact that it's not far from trail bike travel numbers, the label of ‘cross-country’ doesn’t feel relevant to me when the travel of a typical trail bike is excessive for someone my size. The shorter suspension of the Element actually suits my ride style perfectly. I love to ride steep, techy gnar, not big air jump lines (Yup, I’m the girl who goes to the bike park to ride tech trails). I’ll roll just about anything, but I’m not looking for every chance to get airborne. I just don’t need as much travel when my tires don’t really leave the ground!

With the frame decided, the rest of the build was about finding the lightest but most capable components that would allow me to ride this cross-country frame down hill like a trail bike. Finding the right wheels was particularly tricky.

Wheels are usually designed with a 250 lb. rider weight limit, so most off-the-shelf wheels are totally overbuilt for me. Additionally, the bike industry has only prioritized developing lightweight 29 - not 27.5 -wheels in recent years. Most 27.5 wheels on the market are made for enduro and downhill use, so they wind up being on the heavier side of the spectrum.

Therefore, I decided to have custom wheels built for this bike. I chose lightweight carbon rims from Whisky with a relatively low spoke count (28 hole) and selected the ultralight DT Swiss Alpine III spokes – something typically reserved only for road bikes and weight-conscious XC racers. It all turns on DT Swiss 350 hubs, not becuase they're particularly light, but because they're economical and will last forever.

Powerful suspension was needed to maximize the downhill capability of the Element.

Longer fork + Cane Creek Air IL + Rocky Mountain's slackest RIDE-4 setting

I chose 140mm travel for the fork rather than the recommended 130mm. The slight ‘overforking’ coupled with the Element’s slackest and lowest geometry setting really helps the bike feel confident when tackling steep terrain. In my case, Rocky Mountain’s Ride 4 geometry adjustment system was just what I needed to expand the potential of this bike while tailoring it to my unique needs.  

For rear suspension, the Cane Creek Air IL shock is an absolute powerhouse on descents. For such a small shock, it makes for incredibly smooth riding when the trail gets rough. It feels like it came off of a much longer-travel bike, offering far more control than the cross country shocks that often come stock on bikes in this category. As an exceptionally lightweight rider, the wide-ranging adjustability of the Air IL allows me to tune my rear suspension exactly how I need it.

In the past, I’ve had trouble one-finger braking because my index finger just isn’t long enough to wrap around a standard brake lever comfortably. This, in turn, has limited my confidence on the bike.

I chose Hayes Dominion A4 brakes because they are the only brakes that offer ultra small levers that fit my hands. These levers are aptly named “SFL” meaning “Small Finger Lever.” Official naming aside, I just prefer to think of these as the “small f**king levers.” They’re tiny – and therefore perfect.

Apart from a better fit, the Dominions are super powerful brakes designed for downhill bikes. This has totally elevated my ride and the way I can attack steep trails.

The Cane Creek eeWings were an obvious choice because they are super lightweight and bomb-proof. In fact, these cranks are about half a pound lighter than basic stock options. Plus, they are stylish beyond compare-isn’t that reason enough? I chose 160mm length because it's more comfortable for my little legs.

So sexy.


To match my eeWings. They offer smooth ride quality and undying style.

Cane Creek GXC Stem

with Fifty Series Headset


Every good bike build should have two pieces of flair. The first of which is my custom pink GXC Stem, a one-off colorway that was a special project by Cane Creek’s product team. The second is my Tenet Omen pedals in rose gold. These all-American, machined pedals are the perfect match for my one-of-a-kind stem.

If you look closely under the stem, you'll see the Cane Creek Fifty series headset keeping my handlebars and fork turning smooth. These are super durable and well-sealed. I used an old Cane Creek AER series top cap to finish it off. These top caps had machined pockets for a few silly grams of weight savings and have a unique look.

Keep in mind this is an extra-small, short-travel frame riding on small wheels. It's still pretty big sitting next to me, but it's a far better fit than my previous bikes. Click through the gallery to see more.

My previous mountain bike, a popular aluminum 29er from a leading brand, could absolutely plow downhill but it required an inordinate amount of energy to get to the top. Mountain bikes are proportionally bigger and heavier for me than they are for more average sized-riders. The thought of shouldering my old bike to navigate rugged terrain (pictured) was out of the question.


In the end, my Element weighs 27.3 lbs. which is pretty dang light considering what it can do. Any lighter and I’d have to compromise on the downhill fun factor.

In terms of the ride, it’s taken some getting used to. With the Element, I have to be more intentional with my line choices, but the energy I save makes me a more powerful and precise rider on both climbs and descents. In the end, I’m enjoying riding more on the Element because my equipment isn’t bogging me down in the same ways it used to.

In this case, size absolutely mattered—and bigger was NOT better!  

Don’t put yourself (or your bike) in a box. Sometimes you need to defy the labels to find what you really need.
