Cirex SL
The CIREX SL is the ultimate answer for all cross country and down country fans. This bike makes summiting and touring equally rewarding with minimal effort. The super light (SL) frame saves another 200 grams compared to the standard CIREX version and sets the limit of what is technically possible. Its balanced geometry allows high speeds in demanding terrain. And the suspension with 100 or 120 mm travel absorbs fine and rough impacts highly efficiently.







Details
The Cirex SL is the ultimate bike for all cross-country enthusiasts, summit racers and touring riders who want to generate maximum output with minimum effort. But it’s not only a delight to ride during climbs – it shows off its merits on tough downhills as well: The full-suspension MTB is available with 100 mm suspension travel or, alternatively, in a down-country version with 120 mm.
Features
The ultra-lightweight carbon frame and the compact rocker result in a considerable weight advantage. This provides noticeable propulsion, especially when riding uphill.
The more efficient geometry – flatter steering angle, steeper seat angle, longer reach, etc. – is made for steep climbs and demanding descents.
Chainstay protectors on the inside of the chainstay provide comprehensive frame protection. Damage to the paintwork caused by stones and dirt kicked up by the tyre is now a thing of the past.
A chain guide is optionally available as well.

Technology
SIMPLON technologies make the Cirex SL unique: The Flexlink not only replaces a complete joint, which increases stiffness but also reduces wear and maintenance requirements.
What’s more, there’s no cable rub, and the bike sports a clean look thanks to internal cable routing: All cables such as the shift cable and brake line are routed through the inside of the frame. The pivoting cable guide on the main bearing keeps things sleek and also sets the technical standard in terms of cable routing.
