PLUS
A 27.5×3” tire measures out to a 29” diameter and a 26×3” tire measures out to a 27.5” diameter. Combining them with a 40mm rim, results in the ultimate combination of traction, roll-over and versatility without being too heavy, too bouncy, too tall or feeling lethargic on the trail.
 
TAPERED HEAD TUBE
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. A full 1.5” head tube and steerer would achieve this, but would add unnecessary weight and bulk, and limit stem choices. But a tapered 1 1 /8” to 1 1 /2” head tube serves up a significant increase in rough terrain tracking and stability without much of a weight penalty compared to standard 1 1 /8” systems.
 
SHORT CHAINSTAYS
The rear wheel tucks in with short chainstays. With a 12×148 rear hub, you’ve got a stiff and responsive rear end.
 
OUTBOARD CHAIN LINE
A 12×148 rear hub with 3mm offset chainrings minimizes the chance of chain to tire contact with short chainstays and “mid-fat” tires without compromising any pedaling efficiency to a wider q-factor.
 
WHY THRU AXLES?
Securing the rear wheel to the frame by threading a 12mm axle into the rear drop-outs is not only safer, it’s stiffer.  The rear wheel tracks directly in line with the frame, for more precise handling, so you can go faster with more confidence. The increase in stiffness of a 15mm fork axle improves steering & handling significantly. It also puts less stress on the fork’s internals, improving fork durability and performance. The hub drop outs provide a self centering feature for the wheel for fast, easy installation.
 
FORGED BOTTOM BRACKET YOKE
A one-piece bottom bracket shell and drive-side chainstay yoke provide a strong and lightweight solution for the potential clearance issues of 3” tires and double chainrings.
 
TUBELESS
Benefits of a tubeless set-up are reduced rotating weight and the ability to use lower inflation pressures for greater traction without the risk of pinch flats. WTB TCS rims feature a tubeless UST “On-Ramp” profile providing a consistent fit between the rim and the tire for easy installation and inflation.
 
180MM FRONT ROTORS
Bigger wheels and tires generate more rotating mass and traction once they are up to speed. So it only makes sense to use larger rotors to help control that larger wheel in the most efficient manner possible. Sure, 160mm rotors will stop the bike. But when you’re riding like every second counts, braking for the shortest time possible while keeping the bike under control is the goal. And a larger 180mm rotor up front let’s you do this.
 
SEAT & STEERING PLATFORM
A 35mm seat tube with 31.6mm seat post assures the stiffest possible pedaling & steering platform, with a sloping top tube for low stand-over.

Plus Wider Tires:

Plus Tire Mountain Bicycles from Jamis Bicycles:
Jamis Bicycles Leading edge technology for more info: plus series (wider wheel and tires on special designed mountain bicycles) mountain bike for 2017: All Jamis Plus(+) bikes are built with frames designed specifically around 3” tires. This keeps overall outside wheel diameter (OD) consistent with current standards while delivering the plusher, more versatile ride characteristics that come with a fatter tire. A 26+ has an effective 27.5” OD and a 27.5+ has an effective 29” OD. Which also means with our Plus(+) frames you have the ability to run two different wheel sizes without affecting geometry. For instance, on our 27.5+ bikes you can run 3″ tires on a 27.5″ rim…or 2.2s on a 29’er rim. It’s like having two bikes in one! http://www.rbinc-sports.com 2464 Dufferin Street 416 787 4998

Tire Width on standard bicycles:
There are a wide variety of tire widths available for the “standard” tire sizes. Which width is best for you depends on your bike, your wheels, and the kind of riding you plan to do.

For example, the most common width for road riding is 23mm. This is a good compromise between aerodynamics, weight, rolling resistance, and comfort. A narrower tire will have lower aerodynamic drag and lighter weight. At the same inflation pressure, a wider tire will actually have lower rolling resistance on most road surfaces because the majority of the rolling resistance comes from the heat loss of tire deformation. Since a wider tire (at the same inflation pressure) will deform less, it will lose less energy while rolling. Generally though, wider tires are run at lower inflation pressure. The added volume allows lower inflation pressures to be used without the risk of pinch flats and rim damage. The lower inflation pressure will provide a more comfortable ride.
The tire widths that you can use on your bike are determined by the rim width and the frame clearance. The chart included here shows the range of tire widths that can be used for a given rim width. The rim width measurement is the inside width of the rim (i.e., the width of the bead seat in the rim). This is a fairly conservative range; you can probably get away with using a tire that is narrower or wider than the range indicated. If you use a tire that is too narrow for the rim, you’re more likely to get pinch flats and risk damaging the rim if you hit pot holes or other road hazards. If you use a tire that is too wide for the rim, you risk damaging the rim and tire, and are also likely to have handling problems.
A bike frame designed for 23mm tires is unlikely to have the clearance between the tire and frame to support a 42mm tire, even if the rim could accommodate such a wide tire. Most road bike frames can accommodate a tire as wide as about 28mm. Cyclocross and touring bikes are generally designed to accommodate wider tires.
We recommend 23mm and 25mm wide tires for recreational road cyclists. The 25mm width is nice for long distance riding since it will provide a more comfortable ride. Narrower widths are worth considering for racers that are looking for every advantage.
For self-supported touring, a wider tire is desirable since the added load can be distributed over a larger contact patch, improving handling and reducing flatting. If your bike can accommodate it, use a tire that is at least 28mm.
Many touring and hybrid bikes will be fitted with even wider tires—up to 47mm wide. These wider tires will definitely provide a cushier ride, so if comfort is your main priority, sticking with these wider tire widths is a good idea. The main disadvantage to the wider tires is weight. Switching to a slightly narrower tire will give you a little better acceleration performance and provide a zippier ride.
For mountain biking, a wider tire (2.0 to 2.5″) will provide more air volume, which is beneficial for riding on loose surfaces. It will also help prevent pinch flats on very rough terrain. If your riding is primarily on hard-pack dirt roads, a slightly narrower tire (1.5 to 2.2″) will reduce weight and provide better performance.
Most modern mountain bikes have rims that are fairly narrow in the interest of saving weight. The cross-country tires that are usually installed when you buy the bike are actually on the wide end of the range that can be accommodated by the rims. While you probably should measure the rims to be sure, most mountain bike rims can easily accommodate a tire that is as narrow as 1.5″ or even 1.3″ without difficulty. These narrower 26″ tires can be a great choice for riders interested in riding their mountain bikes on the road.
