When Jeff Jones released the Jones Plus LWB in 2014, he really wanted to release it as a titanium Spaceframe Plus LWB. But he knew that as a new concept from a small builder, it made more sense for the first examples to be the simpler, more affordable diamond frame design. That bike in 2014 was Jeff’s foray into 29+, but it was more about the geometry than the tires.
First called the Jones Plus, the bike would later become known as the LWB or Long Wheel Base as it was joined by the SWB (Short Wheel Base) 27+ model. While the Spaceframe has been available in a steel version of the SWB and LWB geometry, titanium has been absent from the line up – until now.
What makes the Spaceframe different? More than its swoopy looks, the Spaceframe uses a 3D design that is meant to enhance vertical compliance while keeping a high degree of lateral stiffness. That’s accomplished by using long, slender tubes up top, along with larger, ovalized tubes for the downtube, chainstays, and seat tube. The design also includes a low stand over thanks to the curved top tubes. Add in one of Jones’ rigid truss forks and a full titanium build and you have the bike Jeff has been wanting to build for a while. A light weight, compliant yet rigid plus bike with a longer wheel base and Jones’ signature geometry.
That geometry revolves around a 67.5° head tube angle with 76mm of rake/offset which results in a very short trail number for quick handling. The seat tube is set to 71°, while the bike has 19″ chainstays which contribute to the long wheel base. There are three sizes of frames labeled as 23″, 24″, and 25″ which refers to the length of the top tube. Standover height is about 26.5″, 31.5″, and 33″ respectively.
As for the frame itself, the 3AL-2.5V titanium Spaceframe uses many of the same specifications as the previous Jones bikes with a 148 x 12mm rear bolt oh thru axle out back, and a fat bike sized 150 x 15mm thru axle up front. Equipped with a 68mm wide Eccentric Bottom Bracket, the frame is single speed compatible – or it can be used for geometry adjustments when running different tires.
For the first time, the titanium truss fork is available in three different sizes to match the head tube lengths of each frame. As mentioned, it runs a fat bike width front hub for extra stiffness for the front wheel builds but it also allows you to run a fat front if desired (up to 27.5 x 4″). The Spaceframe is meant for 29 x 3.0″ tires and has plenty of clearance for the biggest 29+ tires available.
When it comes to braze-ons, the frame has a few. Ok, a lot. In addition to triple bottle bosses on the top and bottom of the downtube, there are also additional bottle mounts are the two bigger frames inside the front triangle, plus multiple rack and fender mounts that allow things to be adjusted based on tire size, or used as additional bottle mounts out back.
- Unique Jones Geometry frameset – frame and forks designed together as one
- EBB For geometry adjustment and single speed chain tension.
- 68mm bottom bracket width
- Titanium Spaceframe for excellent standover clearance, vertical compliance, and torsional rigidity.
- Titanium Truss fork for light weight and precisise handling.
- 3AL-2.5V Titanium tubing for a comfortable ride, light weight, and great durability
- Jones TA bolts front and rear are simple, reliable, light, and low-profile
- Excellent clearance for 29+ tires (10mm+ clearance either side with a 29+ tire – with 29er tire you can get a palm in between the tire and stays)
- Ample chainring/stay clearance
- 148mm TA rear end-increased chain/tire clearance allows you to use all 11 and 12 speed drivetrains with the widest 29×3″ tires.
- TIG welded
- Multiple rear rack and fender mounts for the best rack/fender/tire size fit (extra bosses allow you to have the rack at a height to suit the tires/wheels) allowing for a wide range of configurations.
- Triple bottle bosses on top of the downtube–for mounting cages such as Salsa Anything cage OR a standard 2 hole water bottle cage (medium and large sizes also have a standard water bottle mount on top of the downtube, near the headtube).
- Triple bottle bosses underneath downtube –for mounting cages such as Salsa Anything cage OR a standard 2 hole water bottle cage.
- Jones Truss fork – comfortable, precise handling, no brake stutter
- 150mm thru-axle front hub spacing – for more front wheel stiffness and strength and compatibility with the latest generator hubs
- Fork accommodates 29, 29+, and 27.5 x 4” tires
Price and availability
As usual, there is a lot going on with the new Jones so to dive deeper into the mind of Jeff, check out the blog post they put together here. Framesets are available for $4,550 which includes the frame, fork, EBB, front and rear thru axles, plus the necessary bottle bolts, clips, and standard derailleur hanger. Single speed or Shimano Direct mount hangers available separately. Jones estimates that frames will begin shipping the week of April 23rd.
