The Vision Behind FS838: Engineering a True All-Mountain Weapon
What makes a great full suspension mountain bike frame? That question has fueled the R&D at Tideacebike for years. Riders asked for more than just shock absorption—they needed a frame that delivers in the steepest alpine descents, endures high-speed cornering on rocky trails, and maintains structural integrity even under brutal compression.
In late 2023, our product team conducted in-depth interviews across Tibet, the European Alps, and North America’s top bike parks. From Enduro racers to backcountry explorers, one theme kept emerging: “I want a lightweight frame that won’t flinch on steep, technical terrain.”
Enter the FS838 HVP, a product born from this demand. It’s not just a frame—it’s a design philosophy, a toolbox for trail domination, and the ultimate companion for the serious MTB rider.
Technical Overview: A Full Suspension Frame with Pure Trail DNA
Toray T800+T1000 Carbon Construction: Strength Meets Lightweight Efficiency
-
Material: Toray T800 + T1000 carbon fiber
-
Frame Weight: 3500g ± 45g
-
Sizes: Available in S / M / L / XL
The FS838 HVP uses a blend of T800 and T1000 carbon fibers, carefully layered to optimize strength in high-stress zones and minimize weight across the structure. This dual-carbon approach offers both torsional stiffness and compliance, essential for aggressive riders looking for a lightweight yet sturdy frame mtb full suspension design.
Rear Suspension That Responds Like a Pro
-
Rear Travel: 170mm
-
Shock Spec: Trunnion mount, standard 205x65mm, also supports 205x60mm and 205x62.5mm shocks
-
Recommended Fork Travel: 170mm–190mm (single crown), max 190mm (dual crown)
Whether you’re dropping into steep alpine lines or floating over roots and rocks, the FS838’s rear suspension platform gives you the travel you need with adjustability built in.
The mtb bike full suspension structure delivers progressive damping that adapts to rider input and terrain irregularities—ideal for both Enduro races and freeride weekends.

Derailleur Hanger: UDH (Universal Derailleur Hanger)
Whether you’re building with a Shimano XT drivetrain or SRAM AXS wireless system, the FS838 is spec’d to work with today’s most demanding MTB components.
Boost rear spacing ensures better wheel stiffness and drivetrain alignment, while internal cable routing keeps the bike clean and protected from mud and debris—ideal for muddy descents and rocky climbs.
Real Suspension. Real Control. True All-Mountain Behavior
Unlike budget frames that offer comfort-focused shock designs, the FS838 is engineered for terrain control. With a long 170mm rear travel and UDH hanger compatibility, it invites customization for extreme trail builds.
Matched with a 180–190mm front fork, the geometry offers balanced descending and climbing performance, maintaining traction over loose surfaces and stability in high-speed berms.
This is more than a mtb full suspension frame—it’s a platform built for the unpredictable.
Real-World Story: Slovak Rider Finds His Ultimate Downhill Partner
In early 2024, Marek, an Enduro enthusiast from Slovakia, ordered the FS838 for his custom build. After pairing it with a RockShox Super Deluxe rear shock and a 190mm dual crown front fork, he took the bike to BikePark Sölden in the Austrian Alps.
“I wasn’t expecting a carbon frame this light to feel so planted on rocky trails. The 170mm rear travel soaked up everything. It felt solid even on 2-meter drops. What surprised me most was braking stability—paired with a 223mm rotor, I had full control even on the longest downhill lines.”
Marek has since completed three regional races with the FS838 and is planning to take it to the Trans-Slovakia Enduro Challenge this summer.
Who Is the FS838 For?
This Frame is Your Match If:
-
You’re upgrading from a hardtail or short-travel trail bike and want more capability
-
You ride rugged terrain with sharp elevation changes and unpredictable trail features
-
You prefer lightweight carbon over heavy-duty alloy for better climbing and acceleration
-
You want a full suspension frame mtb that’s future-proof and compatible with current drivetrain & brake standards
-
You appreciate modern frame design, clean aesthetics, and internal routing
Expert Opinions: FS838's Global Rise in the MTB Scene
Multiple forums and independent riders from Europe and Asia have begun posting their builds of the FS838 online. In Germany’s MTB-News.de and France’s VTTmag, discussions highlight its impressive geometry and thoughtful detailing.
“For a frame in this price bracket, the FS838 punches above its class. It holds its own against big-name brands like Trek, Commencal, and Yeti. The flexibility to use both 29 and 27.5 wheelsets with full Boost spacing makes it very versatile.”
As global interest in aggressive trail riding grows, bikes like the FS838 provide a budget-accessible but high-performance solution.
Suspension Technology Breakdown: Why Full Suspension Matters
According to a report by BikeRadar, full suspension bikes have seen a 20% increase in adoption among trail riders since 2022, especially in Europe and North America. Riders want more control, comfort, and speed.
Key advantages of full suspension include:
-
Improved traction over rocks and roots
-
Less rider fatigue on long rides
-
Greater confidence in technical descents
-
Better braking performance through enhanced ground contact
The FS838’s 170mm travel, progressive kinematics, and modular shock support make it an ideal example of what a modern carbon mtb bike full suspension should deliver.
