The latest versions of the ever evolving Jones bicycle...
A Jeff Jones designed frame and fork provides an exceptional handling bike. Taking the 29”/700c wheelsize these bikes will suit a rider looking for an extremely capable, assured, sweet-riding, unsuspended bike – there are 3D SpaceFrame versions in titanium and now steel and the new traditional Diamond frame in steel. The frames come in a size 23”. The framesets can be bought as a complete bike, rolling chassis or frameset; geared, singlespeed – for dirt or pavement riding.
As with all Jones bicycles every order will be carefully considered and discussed with each individual customer. All will be assembled, tested and tuned by Jeff. All have options and extras available.
Titanium Spaceframe and Truss fork
This is, currently, as good as it gets. The titanium Spaceframe and Truss fork deliver the rigid bicycle that is anything but. Laterally stiff to deliver the power with a vertical compliance that softens the ride? Yes, but this is only the icing on the cake. The Jones geometry ensures the best handling bike there is. It really does need to be ridden to appreciate it. Titanium, used here, provides strength, stiffness and compliance in a light, durable bike. The Jones geometry makes it all worthwhile. Note: headset shown is available, but not included in the frameset price.
Steel Spaceframe and Truss fork
Steel frames have the same geometry, clearances, features, gearing options, handling and balance points as the titanium frames but at a lower cost, heavier weight and a different feel. The ride is similar to the ti frame (it has the Jones geometry after all) but it is different. It does feel vertically stiffer compared to the titanium Spaceframe but it's a very good, solid feel. It's steel and steel is good. Note: headset shown is available, but not included in the frameset price.
The steel Spaceframe and Truss fork produces a ride that is stiffer than the titanium version but smoother than the Diamond steel model (below). The tubes used can be smaller than the Ti version as steel is stiffer and this then allows the flex to be carefully managed to deliver efficiency and comfort.
Construction: The frame is TIG welded 4130 chromoly with a butted down tube. The cable guides and bottle bosses are brazed on. The fork is all 4130. The frame and fork are ED black and then powder coated for a durable finish.
Steel Diamond frameset and Jones Truss fork
This is the Jones geometry (and superb handling) as a traditional diamond frame. This, being easier to build, costs less than the Spaceframe version, and while it doesn't offer the same compliance, the seat and seat stay tube dimensions have been carefully selected to both improve ride and reduce the weight. What you do get here is a steel version of the incredible Jones Truss fork delivering superb steering, and braking, performance with a feel that is hard to describe and needs really to be experienced. Note: headset shown (is available, but) not included in the frameset price.
Steel Diamond frameset and Jones fork
This is the Jones geometry (and superb handling) as a traditional diamond frame. This, being easier to build, costs less than the Spaceframe version, and while it doesn't offer the same compliance, the seat and seat stay tube dimensions have been carefully selected to both improve the ride and reduce the weight.
Construction: The frame is TIG welded 4130 chromoly with a butted down tube. The cable guides and bottle bosses are brazed on. The latest versions (above) have a clear powder coating, over the decals, on top of the tough powder coat paint finish for appropriately rugged good looks. A full range of frame-fitting bags are available for bikepacking and touring capabilities and the 4130 Cro-Mo Unicrown forks have custom mounts for the Tubus Duo low-rider racks.
Steel spaceframe and diamond frames are also available with a titanium Truss fork option...
The forks all have clearance for 29x2.55", 29 x 3" (29+) and 26 x 4.7” fat tires. Fork spacing is for a 135mm front hub which allows for a very stiff and strong front wheel. The forks are not compatible with rear 135mm hubs.
|Why this bike?
It's a high performance non-suspension bicycle... instead of designing the bike for XC-racing like so many unsuspended bikes I wanted this bike to be better for technical and distance riding... Since this bike is not designed around a suspension fork I'm able to do much more to improve the handling. By designing the frame and fork together and considering the larger wheels I'm able to make a bike that rides very differently to a 'normal' rigid bike (be it 26 or 29er) with a short rake fork.
My bike has a slacker seat-tube and a shorter top-tube than 'normal' bikes... the head angle and rake with this wheel size (more rake, slacker head-tube-angle and bigger wheel) determines the trail which helps determine the handling. Slacker angles keep the rider's weight off the hands and makes the front end easy to lift; the center of gravity is moved back and down for more control, with less shock to the upper body, more traction under braking, and a bike that is much harder to endo. This bike feels quick but also has a laid back feel. It's the best handling bike I've designed.
