About the Helium SLX Disc The Helium SLX Disc is the top of our ultra-gourmet Helium line of bikes. It’s extremely lightweight. The frame tips the scale at 820gr for a size medium, which is only 60g heavier than the rim brake model. By using disc brakes you don’t only have a bike that expertly helps you count altimeters, but provides you with full control in the descent as well. The straight blade fork adds to that sublime handling taking hairpin bends. Furthermore the use of disc brakes increased the frame’s stiffness, thanks to the 12 mm thru-axles. The Helium SLX Disc got aerodynamically optimized as well, by using F-Steerer technology like we did on the Noah Fast. That way every cable can be integrated to create a clean cockpit Seatpost for Complete bicycle : 3T Zero25 Team Stealth 27.2 Tyres for Complete bicycle : Continental Gp 5000 black , 25mm
