Transition Spur Carbon Eagle 90 Complete Mountain Bike 2026

Cross Country

With speed and pedaling efficiency in mind, cross country (XC) bikes are the lightest mountain bikes with the least suspension travel (typically 0 - 120mm).

Trail

Trail bikes are the quintessential “mountain bikes.” If you’re heading into the woods expecting to do it all on two wheels – climbing, technical sections, AND fun descents – you’re looking for a trail bike.

Mountain bikes are built for tackling rough terrain with frames made of durable materials like aluminum or carbon fiber, ensuring stability and maneuverability. They feature suspension to absorb impacts from rocks, roots, and drops, providing a smoother ride.

Engineered to tackle the most challenging terrain with enhanced comfort and control. Unlike hardtail bikes, full suspension bikes feature both front and rear suspension systems that allow the wheels to move independently from the frame.

Carbon is a composite frame material. Unlike metals, carbon is composed of fibrous strands woven into a grid and bonded with epoxy. Carbon is favored by many for its lightness and stiffness but its complexity in fabrication makes it the most expensive option.

The 34 SL brings never-before-seen XC capability into a full-width 34 chassis with up to 130mm of travel. Built for the most technical World Cup XC courses and demanding Downcountry riding, 34 SL adds more stiffness, more suppleness and minimal weight gain from the 34 Step-Cast fork.

Performance Series forks retain the same black anodized 7000 series aluminum upper tubes as Performance Elite, except paired with a GRIP damper. Push-button bleeders are not included but can be purchased separately.

The feel, look and shift quality of the Eagle 90 Shifter 
allow you to ride in a whole new way. Optimized 
cable pull with a revised lever position for maximum 
control. With a new T-Type cable actuation ratio, 
Eagle 90 offers a higher quality of shift than any 
previous mechanical system. 
 

The Eagle 90 Transmission derailleur is the definitive 
answer to how good a cable actuated derailleur can 
be. It features an all-new T-Type cable actuation 
ratio to provide the most precise and crisp shifts 
every time. Utilizing the same Full Mount design 
as its electronic siblings, Eagle 90 is the strongest 
mechanical derailleur we have ever produced. Not 
only is it robust, but the derailleur body features 
replaceable outer and inner parallelogram links, 
skid plate, and a tool-free threaded cage assembly, 
making it the most rebuildable derailleur in the Eagle 
Transmission Ecosystem.

The new Eagle 90 crankset is a sleek, sturdy answer 
to a growing demand for robust and aesthetically 
pleasing components. And with availability down to 
shorter 155mm and 160mm lengths, it gives riders 
more freedom to build their bike, their way. Featuring 
8-bolt chainring compatibility, the Eagle 90 crankset 
includes a silver stamped steel T-Type chainring 
with optional bashguards for durability and protection 
on the trail.

The GX Eagle Transmission (T-Type) chain is the strongest SRAM has ever made. Specifically engineered to optimize Eagle Transmission, this all-new T-Type design features a unique flat top. In addition to this shape maximizing shifting performance and upgrading the aesthetics of any bike, it is developed specifically for the added torque loads of E-MTB thanks to its solid pins that give it incredible strength.

Born from the legacy of two of the winningest brakes of all-time, SRAM Motive Silver matches the capabilities of XC-race and trail bikes. Modern stealth aesthetics and a bold polished black finish pair with wireless superbikes, while a sculpted 4-piston caliper delivers tunable heavy-duty power for traction and control. Motive opens the aperture on what’s possible, giving you the boundless power of more confidence, and in the process redefining what’s required from a low-weight brake. Motive. New powers to go ahead.

Known for its no-nonsense smooth cable actuation, short overall length, and easy serviceability, the OneUp Dropper is a solid choice for dependable and customizable performance.

The Maxxis Forekaster is aimed squarely at modern short travel (100mm-130mm) trail bikes – aka the “downcountry” segment.

• 3C MaxxTerra: A triple compound ideal for trail riding in all conditions - offers more traction than 3C MaxxSpeed, yet provides better treadwear and less rolling resistance than 3C MaxxGrip.
• EXO: A cut and abrasion-resistant material added to the sidewalls.

The Maxxis Forekaster is aimed squarely at modern short travel (100mm-130mm) trail bikes – aka the “downcountry” segment. Intended to be a "Goldilocks" tire, the Forekaster rolls faster than a Minion or even the Dissector but provides more predictable cornering, climbing and braking than the Aspen or Rekon.
