Last year, we made the switch to USA made Enduro Bearings in the bottom brackets on many of our high-performance level models. Why? Because they are the experts when it comes to obsessing about bearings! Enduro Bearings pioneered MAX type bearings, a design previously only used for large equipment such as forklifts and earth movers almost 20 years ago for bicycles to address the challenges associated with mountain bike pivots.
By filling the races with balls, these bearings have 35-40% more load capacity than standard radial bearings. They accomplish this with a special design where the maximum number of balls are inserted into the bearing. The race grooves are deeper on these bearings for more lateral support for the twisting and multiple forces associated with mountain bike pivots. LLU seals give maximum protection against the elements while keeping the 90% fill of Almagard Extra High Pressure Grease inside. We also specify MAX BLACK OXIDE bearings in our carbon frames which get an additional Magnetite treatment for hardness, rust resistance and even more reliability.
In addition to these BB bearings, we’ve also gone ahead and made these bearings standard on our MP4 suspension bikes. The result for you is a much more active and quick rear suspension, eliminating play and wag all at the same time. Out of the box, our DEFCON & XCT suspension bikes with Enduro’s MAX bearings will save you time and money, as they will perform well 2 or 3 times longer than off the shelf bearings.
Though we do make bikes with frame geometry and component sizing specifically targeted for women, not every woman is best suited or fitted on such a bike. We want to be clear about that from the outset. As always, the best advice for buying a bike is to go to your LBS, where you can be properly fitted on a bike. One of our “unisex” sizes just might be the perfect fit for you (though a swap for a saddle with a wider sit-bones platform will likely be recommended). But if you discover that you are, in fact, best fitted on one of our Femme geometry bikes, of which there are many, here’s what you’ll find:
• Top tubes will be shorter; stems shorter too, with seat tube angles possibly steepened, all to reduce the distance from saddle-to-bar for a more comfortable reach.
• Head tube angles may be relaxed and fork rake increased to eliminate or minimize the potential for wheel-toe overlap,
• Bottom bracket height may be dropped so standover clearance is increased and center of gravity is lowered.
• Handlebars will often be narrower with a shorter reach to the flats and drops.
• Brakes/Shift levers will often have a shorter reach as well and cranks arms may be shorter for any given frame size in comparison to the unisex version.
• Saddles will generally be shorter and wider, often with a pressure relief zone.
• We may even alter the weight and stiffness of our frame materials to better suit a lighter-weight rider (see SST info below)
And we make all our Femme bikes in a broad sizing range – from 44cm to 54cm, or 14” to 18”, so you can be assured of finding a Jamis Femme that fits perfectly.
All our frames and forks are tested continually to meet or exceed (in some cases, well exceed) EN standards 14764, 14765, 14766 and 14781 as well as the new ISO 4210 standards. We conduct these tests at our frame manufacturing facilities, but we also use EN accredited testing laboratories such as Intertek and SGS to verify the results of our own tests. If these tests aren’t telling us everything we want to know about our bikes, we increase the loads and cycles, or we determine another way to test. Where current hydraulic testing machines, jigs and hardware aren’t up to the task of emulating some of the forces and impacts our bikes might be subject to, we’ve designed our own.
We relentlessly cycle test for fatigue from pedaling and torsional forces on every single frame size, with deflection tests for stiffness at every point of the frame. Brutal impact tests with massive weights dropped on fixed frames or forks are performed. Then reversed, with weights attached to the frame, the frame hoisted to a given height depending upon product type, then released.
This destructive testing is enormously instructive and important. And it is in continual process. But it’s our ongoing non-destructive testing of frames and forks fresh off the factory floor that’s just as vital.
For our carbon fiber frames, EVERY frame is weighed to make sure it’s neither resin rich nor resin deficient. We also measure the stiffness of each frame in 6 critical areas as a check on lay-up production. Each deflection test must fall within 5% of the standards our machine and field-testing have established. This weighing and stiffness deflection testing guarantees every single frame we produce meets all Jamis manufacturing protocol and will
deliver the ride qualities we defined and demand.
The 27.5” wheel size is not a compromise between 26” or 29”: it’s the best of both worlds. It rails singletrack, floats over trail chatter, is easier to handle and maneuver and allows for lower standover clearances than most 29ers.
Riding fast with control requires steering precision, which starts with the front of the bike. Stiffening this area results in less wheel deflection, more wheel control. Tapered 1 1/8” to 1.5” head tubes and on the Halo XCT and XC serve up a significant increase in rough terrain tracking and stability without much of a weight penalty compared to standard 1 1/8” systems.
Halo models feature oversized head tubes with internal headsets reducing the front-end stack height, resulting in lower top tube standover clearances.
The saddles on our women’s mountain bikes offer female specific widths and lengths. WTB’s Volt with Luxe Zone utilizes a shape which helps increase power output by properly aligning the sit bones while climbing. A flex tuned shell and relief cut-out increase comfort.
Both the Halo XCT and Halo XC feature forks and shocks that offer adjustable rebound damping, a single valve air spring and an easy to reach lockout lever. They’re light and easily adjusted to suit rider and riding style. Sag gradients are printed right on the shock damper body of the Rock Shox Monarch, making perfect suspension setup simple and accurate.
Securing the rear wheel to the frame by threading it into the rear dropouts is not only safer, it’s also stiffer. Increasing the rear axle diameter from 10mm to 12mm on the Halo XCT makes it only stiffer still. The rear wheel tracks directly in line with the frame, for more precise handling, so you can go faster with more confidence. The 142mm hub dropouts provide a self-centering feature for the rear wheel for faster, easier installation.
The 15mm QR fork thru-axles on the Halo XCT offers all the benefits of the 20mm thru-axle design (stiffness!) + the benefits of the standard 9mm QR system (quick wheel removal!) without any of the down sides. The weight of the 15mm system is similar to the classic 9mm system (thanks to the lightweight alloy QR axle & reduction in fork leg weight), but it is nearly as stiff as a 20mm freeride thru-axle. The increase in stiffness improves steering & handling significantly. It also puts less stress on the fork’s internals, improving fork durability and performance.
Our Lock-On grips offer security to ensure no twisting, sliding or migrating even in the roughest, steepest and wettest terrains.
