The carbon frame is characterised by its unusual shape, angular shock rocker, agile geometry and impeccable finish. It weighs just 1963 grams, plus the shock at 339 grams - a great value. But that's only half the battle: The Rock Shox suspension contributes the rest. It does a good job, the three-way adjustment of the shock provides exactly what you are looking for in practice on a marathon bike. Open mode for downhill, a noticeable platform and a lockout for tarmac. But thanks to the good drivetrain efficiency, you can largely ride in open mode on bumpy terrain without sacrificing power. The Reba fork provides more riding comfort than the SID, which is designed for racing. Uphill, you'll be delighted with the enormous traction and riding comfort. But even when pedalling out of the saddle, the rear remains calm. The bike feels manoeuvrable on winding trails, and the short wheelbase contributes to this. On flat sections, it really moves forwards - the only thing missing is the start number on the handlebars. The Cirex doesn't have any weaknesses on the downhills either. Of course, you have to ride with more concentration than on an all-mountain bike, but the rolling behaviour and riding stability are on a high level. As long as you hold on to the handlebars, you can let it go. What do you get for a good 4000 euros? The clever features of the Pro model include the Acros headset with steering stop limiter, triple cranks and the XT Shadow Plus rear derailleur with the option of increasing the chain tension (reduces chain slap). The lightweight wheels are fitted with the new, even faster-rolling Rocket Ron tyres. Nobody needs more luxury.
