Description

The CGR E CARBON-X blends everyday practicality with smooth electric assist and a lightweight carbon frame. A super-lightweight carbon bike with internal cable routing, its capable of anything you are. Weighing just 12.3 kg, it pairs a sleek carbon monocoque frame with the near-silent MAHLE X20 e-drive system for smooth, natural assistance when you need it most. Shimano’s pro-level Ultegra Di2 12-speed wireless groupset delivers flawless shifting, tough Mavic Allroad wheels, and grippy 40 mm Schwalbe G-Ones keep you fast, confident and in control, wherever the road or trail leads.

Electric Motor System

The MAHLE X20 e-drive system gives you lightweight, natural-feeling power that kicks in when you need it. It’s whisper-quiet, stealthily tucked away, and gives you up to 140 km of assistance—or more than 200 km if you choose the optional range extender. With 55Nm of torque and a bigger 350Wh battery, it helps you up the climbs, across rough ground, and through longer days in the saddle. You can even set it to respond to your effort or heart rate, so it’s always working how you want it to—whether you're training, building back, or just riding for the love of it.

Electric Motor System

Groupset

Shimano’s latest Ultegra Di2 delivers lightning-fast, wireless shifting, confidence-inspiring braking, and better all-day comfort. Shifts are instant and accurate, so you can focus on the ride. A wide gear range makes climbs easier, and the lightweight FSA Gossamer chainset keeps things smooth and efficient when you put the power down. With Di2, you are in control.

Groupset

Wheelset

Ride smoother, faster, and further—wherever the road (or trail) takes you. Lightweight and tough, the Mavic Allroad wheels with integrated MAHLE X20 motor deliver responsive power and confident control across any terrain. Paired with 40mm Schwalbe G-One tyres, it’s a setup that’s as eager for hidden dirt tracks as it is for tapping out the tempo on tarmac.

Wheelset

Handlebars

Ribble alloy bars are built for real-world riding, with a compact shape that makes it easy to move between tops, hoods and drops. The ergonomic profile helps reduce pressure and keeps things comfortable, mile after mile. Paired with a matching alloy stem and wrapped in soft bar tape, it’s a setup that feels right from the first pedal stroke—whether you’re heading out for an hour or all day.

Handlebars

Saddle

Stay comfortable and in control, even when the trail gets rough. The hidden seatpost clamp, D-shaped carbon post and Selle Novus Boost Evo saddle work together to soak up the buzz and smooth out the ride.
