Ceepo Mamba-R (Part 2): Road Rocket with Aero Swagger

Introduction

Welcome back to part two of my three-part series on the Ceepo Mamba-R, the bike that’s been my trusty steed for crushing every terrain. After tearing up gravel in part one, we’re now hitting the tarmac to see how this rig performs as a road rocket. Ceepo’s 2025 return to the US market through Ceepo Bikes USA in Lansdale, PA, and their sponsorship of Team BIKE AID, racing the Mamba-R in road, gravel, and triathlon events, has this bike stealing the spotlight. Since 2022, the Mamba-R’s design has stayed largely unchanged—a refined classic that’s not chasing featherlight status but delivers serious value for multidiscipline riders who want one bike to do it all. In this installment, we’ll dive into its road cycling chops, from its aero-driven design to its aggressive geometry. Stay tuned for part three, where we’ll explore its triathlon prowess. Let’s roll!

Specifications

Here’s the rundown on the specs that make the Mamba-R a tarmac terror:

Specification	Details
Frame Material	Carbon fiber (Japan Toray ®)
Tire Clearance	Max 35c (easily fits 30/32mm road tires)
Weight	Frameset: 1,120g (M size, naked); Fork: 450g (uncut steerer 300mm, naked)
Groupset Compatibility	Mechanical and electronic, 1x and 2x
Bottom Bracket	BB386EVO (potential creaking if not installed properly)
Brake & Rotor	Flat Mount, 160mm default (140mm rear requires adapter)
Seat Post	CEEPO tri-seat post (reversible)
Di2 Battery Slot	Integrated in downtube
Colors	None More Black, Kamado Red
UCI Compliance	Yes

These specs scream road performance, with a stiff carbon frame, generous tire clearance for modern road trends, and a slick Di2 battery slot for clean electronic shifting. The BB386EVO and 160mm brake setup have minor quirks, but we’ll get to those.

Road Performance

On the road, the Mamba-R is a straight-up speed machine, built with Ceepo’s aero obsession front and center. The truncated airfoil tube shapes and kammtail downtube slice through the wind, giving you an edge on flats and descents. The frame’s stiffness is unreal—every pedal stroke feels like it’s launching you forward with zero watts wasted. Sure, at 1,120g for the frameset, it’s not the lightest, but who cares when the power transfer is this crisp? I’ve pushed this bike on group rides and solo sprints, and it responds like a thoroughbred, snapping out of corners and holding speed like a dream.

The tire clearance is a game-changer, easily fitting 30/32mm tires to keep up with the latest road cycling trends toward wider, comfier rubber for better grip and lower rolling resistance. Think of pro setups like those on the Tour de France, where 30mm tires are now standard. The Mamba-R lets you join that party without missing a beat.

Comfort and Fit

The Mamba-R’s aggressive geometry is built for speed demons. With a low stack height, you’re slammed closer to the road for maximum aero gains—think Cervélo S5 (stack: ~496mm for size 54), Specialized Tarmac SL8 (stack: ~514mm), or Trek Madone SLR (stack: ~507mm). The Mamba-R’s stack is in the same ballpark (~500mm for medium), making it a touch more aggressive than a Trek Domane but right in line with pure race bikes. The carbon frame soaks up road buzz, keeping you fresh on long rides, while the FSA SMR stem lets you fine-tune your fit for comfort or all-out attack mode. It’s a bike that begs you to drop the hammer.

Versatility

This bike’s versatility is its superpower. Run it with 28mm tires for pure speed or slap on 32mm tires for extra comfort on rough roads. The frame handles 1x or 2x drivetrains with ease, and the Di2 battery slot in the downtube keeps electronic setups clean and hassle-free. Whether you’re chasing Strava segments or cruising on a century ride, the Mamba-R adapts to your style. It’s a value-packed performer for riders who want one rig for road, gravel, and (spoiler alert) triathlon.

Drawbacks

No bike’s perfect, and the Mamba-R has a couple of quirks. The BB386EVO bottom bracket, while stiff, can creak if not installed with precision—a common gripe with this standard across brands like Pinarello or Scott. A good mechanic and some thread locker can keep it quiet. Also, the disc brakes are set up for 160mm rotors by default, so if you prefer a 140mm rear rotor for lighter weight, you’ll need an adapter. Minor hassles, but worth noting for tinkerers.

Who Should Get This Bike

The Ceepo Mamba-R is for road riders who crave aero speed and versatility. It’s perfect for racers chasing podiums, weekend warriors hunting KOMs, or multidiscipline riders who want one bike for road, gravel, and beyond. If you love aggressive geometry and don’t obsess over grams, this bike delivers serious bang for your buck.

User Feedback

Riders are buzzing about the Mamba-R’s road performance. A user raved, “This bike is stupid fast on the road—stiff, aero, and handles like a race bike should.” My own rides confirm it: the Mamba-R feels like an extension of your body, carving corners and powering up climbs with confidence. It’s a bike that makes you want to push harder.

Rating

The Ceepo Mamba-R is a tarmac-slaying beast that pairs razor-sharp aero design with versatile performance for road riders who demand speed and adaptability.
