Since 2014, the Jamis Renegade Series has been defining versatility in modern adventure bikes. The key is a finely tuned frame and fork design that maximizes handling and comfort whether you're road riding with 28c tires, adding a rack and fenders for commuting on 32's or exploring the backcountry wilderness fully loaded up on 40c rubber.
(Our steel and aluminum Renegades will accommodate up to a 700cx42/650x47c tire.)
Read on to understand Jamis' approach to adventure frame design and how it keeps the Renegade's superior ride quality consistent regardless of tire choice and frame size, on-road or off.
Starting with a wide and consistent stack and reach range, we set out to design a frame that could handle on or off road conditions while maintaining a comfortable and consistent ride. As you start to review the geo chart you will noticed we have 3 different fork offsets, BB drops and rear center measurements depending on frame size. This is unique.
We set out to ensure every Renegade rider will experience the ultimate in adventure bike performance regardless of their frame size. Most of our competitors simply design one fork and strap it to every frame size. While this may work just fine for a bicycle that's designed to be ridden with a single tire size (think a road racing bike), it significantly impacts the handling and ride quality of an adventure bike when swapping out your 28c's for 32s, 40s or even 47c tires.
Add size specific tubing, where we vary the diameter of the frame tubing depending on frame size and 2 different sized rear triangles and you have what we feel is the perfect adventure geometry for all sized riders and the best riding adventure bike period.

ADVENTURE FRAME DESIGN
RENEGADE LEADS THE WAY: VERSATILITY
Renegade enables you to be a commuter in the morning, leader of the after-work group ride and take off for a 300-mile bikepacking expedition over the weekend. All with a single bicycle. With over 20 fork and frame mounts you can now choose to mount fenders, rear carrier, low-rider front carrier (or two cages for water bottles/storage) and three front triangle water bottles. Add clearance for 700cx42/650x47c tires on our steel and aluminum models, and it's clear the Renegade series is equipped to accommodate any adventure.
RENEGADE LEADS THE WAY:
ADVENTURE FORK DESIGN
Enhanced Compliance Offset (ECO) fork blades are swept forward several millimeters to provide extra vertical compliance for a more comfortable and controlled ride without any compromise in lateral stiffness. This is possible in part due to the ECO’s reinforcing rib on the inside of the fork legs. The integration of a 12mm thru-axle into our fork maintains all of the characteristics of our ECO design while adding the benefits of increased front-end stiffness and further reduced weight.
ENHANCED COMPLIANCE OFFSET
ENHANCED COMPLIANCE OFFSET
A fork’s sole purpose is to secure and steer the front wheel. But there’s a whole lot of engineering involved in making sure your bike doesn’t just steer, but steers “just right”. Not too sluggish. Not too twitchy. And has sufficient lateral and torsional stiffness to hold a line at speed, under turning loads, while still being able to dampen road vibration for comfort and control.
One of the chief variables between forks is a measurement called “rake”. Rake refers to the curvature or angle of the fork blades as measured from the center of the steer tube to the center of the dropouts. More rake for any given head tube angle will equate to faster steering, with less input required to make the bike turn. But steering characteristics are not determined by rake alone. It is “trail”, a measurement calculated from wheel size, head angle AND fork rake, which tells us how fast a bike will actually steer. More trail yields slower steering, less trail produces faster steering.
One of our design goals for the Renegae, Endura and Ventura was to increase fork compliance for greater comfort and control, without changing its’ already optimal steering characteristics, lateral stiffness or torsional rigidity. Torsional rigidity in a fork is crucial. A torsionally flexible fork will slow steering on descents and fast corners. There will be a noticeable lag between handlebar input and the bike’s reaction.
We accomplished our goals with E.C.O. -- Enhanced Compliance Offset. The fork blades on Renegade, Endura and Ventura model’s are swept forward a few millimeters to reduce the angle of the fork leg to the road, which increases vertical compliance for a more comfortable and controlled ride. A reinforcing rib on the inside of the fork legs assures both lateral and torsional stiffness. Most importantly, the “just right” handling traits remain unchanged, even with the more forward bent fork blades, because the ECO trailing dropout design negates the increase in fork rake, thereby retaining the original trail and optimal steering characteristics.
RENEGADE LEADS THE WAY: A FULL RANGE...IN A FULL RANGE OF SIZES
The Renegade is ready for any adventure, no matter which Renegade you ride. The long and tall endurance geometry is designed specifically to ride comfortably all day on the road or in harsh conditions off-road. The smooth ride of the full carbon fiber Renegades set the bar for how we designed the steel and aluminum bikes. With disc brakes and the ability to mount up to a 47c tire, these bikes are ready to go just about anywhere. All you need is the desire to push, pedal and explore.
Load capacity for mounted racks = 25lbs front and 25lbs rear.
