The new Jones Steel Spaceframe Plus SWB brings the benefits of 27.5" Plus tires to the proven Jones 29 geometry to create a new kind of Jones Plus! This is the first revision to the original Jones 29 frame geometry in about 10 years, and it combines aspects of the Jones Plus LWB and the original Jones 29 to make a short wheelbase bike with clearance for larger tires, new hub spacing, more bosses, and slight geometry tweaks. The result is a bike that maintains the agility for which the Jones 29 is known, while adding stability, and more wheel options! Initially only available in the Medium (23" ETT) size (equivalent to the Medium (24") size in the Plus LWB). If you need a small or large, please put your email address in the "notify me" box after choosing the option you would like! This will help us prioritize the next models to work on.
The Jones Plus SWB is the evolution of the original Jones: the Jones 29. The Jones 29 has been a truly groundbreaking bike since its introduction back in 2009, and this is the first major update it's gotten—which speaks to its enduring design, but recently Jeff saw developments which, together with little tweaks he'd had in mind, warranted a real update. Jeff tweaked that proven geometry to allow for clearance of 27.5x3+" tires front and rear (though it will fit up to a 4" tire in the front). This results in a 11mm longer rear center, which, when combined with a 1° slacker headtube angle, gives the frame an 11mm longer front center as well. This 22mm longer wheelbase gives the Plus SWB just the right amount of added stability when compared to the original Jones 29—without affecting the bikes superbly nimble handling.
It has the same 148x12mm thru-axle (boost) rear end, 150x15mm thru-axle front hub spacing as the Plus LWB—which allow you to use generator hubs designed for fat bikes, as well as build extremely strong wheels for both the front and rear. Three water bottle bosses on the top and bottom of the down tube to allow you to mount three-hole bottle cages such as the Salsa Anything Cage. Comes with Jones TA Bolts front and rear for simple, reliable wheel mounting. Jeff wanted to pare-down the thru-axles he used to the minimum by simplifying them as much as possible to make a system that is as reliable, light, and durable as possible. The result is the Jones TA Bolt. It works just like a standard quick release thru-axle, but instead of just threading it in until it's tight enough to clamp the quick release, you just tighten this one until it's tight, using a 5mm allen wrench. Jeff says it reminds him of tightening the wheels on his bike as a kid, and he is really happy with how positive and solid the connection feels.
Available in Black, or Blue (Pantone 646 C). Both Colors feature an ED Black underlayer to protect the frame from rust, and a matte clearcoat.
Please note that while the photos of the blue frameset are current, but the black photos are pre-production, so some of the bosses are no correct.
This is a frame, fork, EBB (bottom bracket), front and rear TA bolts, water bottle bolts, clips, and standard derailleur hanger. If you would like a single speed or Shimano Direct Mount hanger, get them here!

• Rider height between 5' and 5'8" would fit the Small (22") Jones Spaceframe Plus SWB 148 well.
• Rider height between 5'2" and 6'2" would fit the Medium (23") Jones Spaceframe SWB 148 well.
• Rider height between 6' and 6'6" would fit the Large (24") Jones Spaceframe SWB or Diamond Plus SWB 148 well.
All sizes of the Jones Plus SWB share the a 69° head tube angle, and a 72° effective seat tube angle. The chainstays are 449mm (17.68") long. The effective top tubes vary with each size, but be sure to note that because the seat tube angle is steeper than on the Jones Plus LWB, a medium Plus SWB will have an ETT that is an inch shorter than the same size in the Plus LWB. The difference in seat tube angle is also why Jeff recommends a setback seat post on the Plus SWB, and a zero-offfset on the Plus LWB.

The eccentric bottom bracket (EBB) allows you to adjust chain tension for single speeds and gear hubs, or to change your bottom bracket height to suit your preference for differing terrain or wheel sizes. More information in this blog post.
