2025 Rocky Mountain Instinct PowerPlay SL C70

This is a mountain bike that earns your trust from the first pedal stroke forward. It adapts, it responds, and it supports you when the trail gets serious. Whether you're climbing, descending, or linking tech sections, the Altitude C99 SRAM holds its ground and lets you ride with better control and confidence.

The 2024 Rocky Mountain Altitude C99 SRAM is built for those who push their limits on the toughest trails. This bike does a lot of heavy lifting without feeling like a burden, thanks to its carefully engineered carbon frame. Rocky Mountain’s SMOOTHWALL™ carbon keeps the frame light but tough, ready to absorb hits and respond quickly when the trail gets technical or steep. Smoothwall carbon frames are 3D designed with carefully optimized frame thickness at every point, and they also use different types of carbon in specific frame areas to maximize stiffness and impact resistance.

One thing you’ll appreciate is the RIDE-4™ adjustable geometry system. It lets you tweak the bike’s angles and bottom bracket height in four different settings. Climbing? Descending? Technical switchbacks? You can dial the bike's feel to match the terrain. This is a big advantage when trails keep changing on you.

Out front, the RockShox Zeb Ultimate Flight Attendant fork offers 170mm of travel and smart suspension tech that adjusts on the go. No more fiddling with settings mid-ride. The fork senses the trail and adapts automatically.

In the back, the RockShox Super Deluxe Ultimate Flight Attendant HBO shock, with 160mm of travel, keeps you connected to the trail while smoothing out rough patches. Flight Attendant uses a suite of sensors to read rider and terrain inputs to anticipate the perfect suspension position. AXS-enabled and cable free, Flight Attendant is an integrated part of the SRAM AXS ecosystem. That hydraulic bottom-out control helps prevent harsh impacts, so your ride stays controlled even when things get gnarly.

Shifting is straightforward and precise thanks to the SRAM X0 Transmission drivetrain, known for crisp and reliable gear changes. You'll get a wide cassette range from 10 to 52 teeth, which covers everything from fast flats to steep climbs with ease. Power gets transferred efficiently through the SRAM DUB BSA 73 Wide bottom bracket and crankset, so you can focus on the trail, not your bike.

You'll also find a set of SRAM Code RSC 4-piston brakes. They deliver solid bite and smooth modulation, so when the trail pitches down or narrows, you'll feel confident and in control. There are no surprises when you need to slow down fast.

The wheelset balances strength and lightness with Race Face Era carbon rims laced to Vault hubs using straight-pull spokes. This means the wheels stay stiff but absorb trail chatter well. Tires are Maxxis Assegai 2.5 WT 3C MaxxGrip EXO+ up front for sticky, reliable grip and Maxxis Minion DHR II 2.4 WT 3C MaxxTerra DD out back for traction and durability. Both tires have extra sidewall protection to reduce the chance of flats and tears when the terrain turns rough.

The cockpit features a Rock Shox Reverb AXS wireless dropper post that moves your saddle up and down with a simple remote press without messy cables. The FSA Orbit NO.85 headset lets the bars turn smoothly, paired with a Rocky Mountain 35 AM stem for direct control. Wide Race Face Next R handlebars feel stable and nimble at 35x780mm, complemented by comfortable ODI Elite Pro grips that reduce hand fatigue. Saddle choice is the WTB Volt Race 142, known for balancing support and comfort during long days on the trail.
