BUILT RIGHT. HERE.
Building every wheel by hand in Eugene, Oregon, USA
WE ARE A TEAM
We’re athletes. We ride, we
run, we ski, we climb and we
swim. We believe in balance
and we take advantage of
every opportunity that life
presents.
We’re craftsmen. We
understand that quality and
workmanship matter; your
rides are just as important to
us as ours. By hand-building
our wheels with parts that we
design, test and manufacture,
we provide our customers with a consistently great experience and unparalleled reliability.
We’re perfectionists. We’re driven by technology and performance. No matter the level at which our
customers ride or race, we’re focused on providing them with best-in-class wheels.
We’re local. We’re committed to our community and the cycling community at large. We show our
support through events, volunteering, participation, and “cyclevangelism”.
BUILDING BY HAND
Simply because it’s better.
Just like that pie made from scratch by your grandma, wheels built by hand are just plain better. They
offer noticeably superior ride quality along with measurable gains in durability.
We know that there are faster and cheaper ways, but we’re in the business of making exceptional wheels.
We want you to be as proud to ride them as we are to build them.
At Rolf Prima, every wheel goes through the same painstaking build process. This process is rigorous and
it enables our wheels to run truer longer… without the need for constant attention.
Ride the difference.
TESTING
Building a Best-In-Class wheel isn’t done with just parts out of a catalog. It needs to be engineered. And
then it needs to be tested. And then tested again.
At Rolf Prima, we pride ourselves on our engineering, but we don’t pat ourselves on the back until we’ve
validated it through testing. And not just any testing; we’ve developed a testing regimen that puts our
wheels through the literal ringer with tests measuring, among other things, stiffness, impact, braking,
aerodynamics and durability. Why? Because you deserve it.
TECHNOLOGY
Paired Spokes™
Bringing the spokes to the
rim in pairs neutralizes the
left and right outward pulling
forces allowing us to build
true wheels on lighter rims
with fewer spokes.
Differential Flange Diameter™
Our patented oversize non-drive
Differential Flange provides
leverage to transmit drive torque
in the rear wheel to the non-drive
spokes, thereby increasing the
number of torque absorbing
spokes.
Dish Reducing Design™
This patented technology
increases the bracing angle
of the drive side spokes to
improve wheel stiffness.
Delta Rim Technology™
Our Delta Rim Technology
improves airflow and stability
in straight on and crosswind
situations. This wider rim
isn’t just faster; the shape
and additional tire support
also improve cornering
and handling in all riding
conditions.
Jacketed Nipple Design™
The deeper the rim, the more
a spoke must bend along its
path to the hub flange. Our
patented Jacketed Nipple
Design moves the bend of
the spoke away from the
high stress area of the spoke
threads and
increases spoke
life significantly.
Self-Aligning Nipple™
Our patented Self-Aligning
Nipple design allows the
nipple to rotate in a ball
and socket configuration to
minimize spoke
bending and
increase spoke life.
CARBON CLINCHERS
Carbon is no longer the exclusive domain
of the racing community. Our carbon
clincher line, built on our Delta Rim
Technology, offers best-in-class
performance, excellent aerodynamics,
durability and overall handling. It provides
all the benefits of a “race-day” wheelset,
with the robustness of a Rolf Prima build.
Our carbon clinchers are not just “race-day”
wheels; they’ll also be your “I’m going to chase
that rabbit down today” wheels.

Extensive engineering, development and testing have
resulted in our fastest, best handling and most durable
wheels yet – great in all conditions. Multiple rim depth
options - ranging from 42mm to 60mm deep.
Ares - Race day, any day. Pressure, temperature, layup. Important things you don’t need to think about. Because we did.
CARBON TUBULARS
Who doesn’t want every advantage on
race day?
Our TdF line was designed with just that in
mind, offering faster speeds without weight
penalties. The result of countless hours of
design, development and testing, our TdF
models offer seamless integration of our Delta
Rim Technology on a carbon tubular platform.
Not only are the TdF models among the lightest
wheels on the market, they also boast exceptionally low
wind resistance. Multiple rim depth options - ranging from
42mm to 60mm deep.

VIGOR
The wheel that put Rolf Prima on the map.
The Vigor was born, bred, and engineered
to be your race-ready and everyday wheel.
The Vigor offers aerodynamic speed and
handling benefits unmatched by any other
alloy wheel. Designed with our Delta Rim
Technology the Vigor line offers a lightweight
aero wheel with the exceptional durability
and handling that you’ve come to expect
from Rolf Prima.
With options for disc brake hubs, clincher or tubular rims
and an RS version for heavier riders or rougher terrain,
there’s a Vigor for every rider and every ride.

ELAN
Much more than just a climbing wheel,
our Elan line not only trims more weight
from an industry-leading lightweight
wheelset, but also incorporates our Delta
Rim Technology to improve stiffness and
handling. All while remaining firmly in the
aero category. The Elan excels at steep climbs,
quick accelerations and all-out fast riding.
With a disc brake and 650c wheel size options,
there’s an Elan for all.

ECHELON
The Echelon is Rolf Prima’s race-capable
work horse. Made with the same refined
hand-building process as our higher-end
models, the Echelon line pairs custom hubs
and our own US-made rims. The end result?
Wheels with great stiffness, handling, and
dependability for riders on a budget.
When the road gets rough, the Echelon is
unmatched.

ASPIN
Taking a leap forward to incorporate
more aerodynamic benefits and shape,
the Aspin wheel line is built upon custom
hubs and Rolf Prima’s own US made rims.
A dependable option and a premium wheel
for a wide range of riders, the Aspin line is a
great choice for training miles or race day.
New additions include a disc brake compatible
hub and new 650c wheel size.

TANDEM
When your wheel is the wheel to which
all other tandem wheels aspire, you know
you’ve done something right. We should
know – we’ve been engineering and
building performance tandem wheels for
over 10 years.
Our alloy option incorporates the same
Delta Rim Technology used in our Vigor line,
and is engineered for the rigors of tandem use.
Looking for even more speed? In 2014 we introduced
the Tandem Disc Carbon, which has quickly become the
wheel of choice for the tandem teams looking for that
added edge.

HUBS
RIMS
The hubset is the center of it all. Our goal is a hubset that is so dependable that you
forget that you have it. We’ve chosen materials that are not only tough, but lightweight
as well. You’ll find CNC machined titanium freehubs, CNC machined aluminum
hub shells, Enduro ceramic cartridge bearings and independently sprung
hardened steel pawls in our line.
We are obsessive about this because we understand it – you want
something you can count on for your big rides, races and long
tours.

In 2013 we began the journey to build our own aluminum rim
manufacturing line in our Eugene, Oregon facility. We were
proud to begin delivering rims in 2014, just one year later.
Making an aluminum hoop with
holes is easy. Making a precision
bicycle rim is not. The details and
refinement required are downright
painstaking. It’s necessary.
It’s rewarding.

MOUNTAIN
For some, mountain biking is an every
season passion. Whether it’s arranging a
shuttle for an all day long epic adventure
or waiting for that favorite river trail to dry
out, we know. We live it. And we’ve got the
wheelset that will make your ride more fun.
We’ve spent countless hours in the design and
testing of our Ralos and Rage models, so your
only concern is how to get to the trailhead. Mount
them up tubeless if you like and hit the dirt.
We’ll build them to suit your preferred configuration.
Available as 29”, 27.5” (650b), 26”; Front axle: 9mm/15mm thru,
Lefty; Rear axle: 135mm/142mm thru, XD driver for 1x11.

CYCLOCROSS / GRAVEL
Gravel adventuring and cyclocross racing
appear to have little in common, but both
demand tough, fast, dependable and
versatile wheels. Whether the goal is hot
laps to the finish line or rambling into the
unknown on a forest service gravel road, the
last thing you want to worry about is your
wheelset.
Every model offered in our cyclocross and gravel
adventure line has been thoroughly put through its
paces. So race them, train on them and ride them
wherever the course, road or gravel may lead - because we
want the stories to be about the adventure and the journey.
