Merit Jumbo 750d Gravel Frameset

Conquer any terrain with our Jumbo 750d gravel bike—engineered with larger wheels for smoother rides, superior traction, and a perfectly proportioned look in larger sizes.
This bike isn't just for the tall guys. It's actually for everyone. The frame is designed for 750d wheels, but regular 700c (29") sizes can be used as well. However, in L-XXL sizes the bike looks best with 750d and that was one of our goals. To incorporate bigger wheels into a gravel bike. We don't want a tall guy to look like a bear on a tricycle anymore. At the same time, increasing the wheel size on a gravel bike has several advantages. 

We give riding a new dimension

• Sizes L, XL, XXL looks proportionally much better. 
• Better rolling over obstacles on the route.
• Large boost wheels absorb shocks better. 
• Better traction improves braking and handling. 
• Better inertia of big wheels keeps speed. 

FRAME DETAILS AND FEATURES

Frame Tyre Clearance
We've adapted the frame for the big 750d wheels up to 45mm tyre width, but also for the classic 700x50 (29x2.0") and narrower. You can choose what you want to use.

Road Boost Axles
Because of the use of the big 750d wheels, we extended the front and rear fork to boost 110 and 148mm. There is more wheel lateral stiffness, more vertical flex and better chain line.

Keep Short Chainstay 435mm
The short chainline adds great characteristics to the bike, makes the bike more agile and adds confidence in descents.

Smart Full Internal Routing
Inside routing looks best. Cables are protected and does not interfere with front bags and so on.

T47 Bottom Bracket
Most stressed parts of the frame are robust to keep the ideal frame stiffness. Threaded T47 BB is perfect option for power transfers. 

Brake Mount
The frame is ready for flat mount brakes, but directly for bigger brake rotors. Rear is ready for 160mm without any pad and front for 160mm or 180mm rotors.

UDH Hanger
One hanger what you can buy anywhere. The frame is also ready for the latest Transmission shifting.

Standard Seatpost Clamp
We used a classic and proven solution. Traditional 31.8mm band and the most common 27.2mm seatpost for maximum compatibility.
