The Emonda ALR 5 Disc is an aluminum road bike to compete, superlight and reactive. The advanced design of the Kammtail aluminium tubes and the competition geometry give you the elegant look and management of a carbon bike, with the price of one aluminum. If we add components such as transmission Shimano 105 and the powerful hydraulic disc brakes that allow to stop in all conditions, the result is a bicycle designed to perform both in competitions and in group outputs.

It's ideal for you if...

You are looking for all the advantages of a bike designed to offer you uncomplex performance, with the added value of an affordable aluminum frame, which also has an elegant design and management that you could only expect from a carbon frame, and with the reliable brake power of the disc brakes.

The technology that incorporates

Incredibly lightweight Alpha Series 300 aluminum frame with Kammtail tubes for greater aerodynamics, and Invisible Weld technology, an Emonda SL carbon fork that absorbs the vibrations of the road, guided by internal cables in the frame and fork, complete group Shimano 105 2x12 which offers accurate and reliable change, powerful flat-mount hydraulic disc brakes and tubeless ready wheels.

The last word

A similar advanced aluminum frame for carbon design and performance and reliable transmission Shimano 105 turn this bike ready for competition into an incredibly versatile machine.

You'll love it!

This ultralight aluminum frame has been designed to compete and has an impeccable internal wiring.

It is fast in the ascents, takes the curves accurately and descends safely
