Standert’s up to date Kreissäge RS aluminium race bike goes aero

Standert has launched a brand new model of the Kreissäge RS. We reviewed the earlier model and gave it 4 stars, for it is type and it is aggressive dealing with. It now boasts aero creds, so as to add to it is hardcore race chops.

Described by the German model as a “daring reimagination of the trendy aluminium race bike”, it now options CFD (Computational Fluid Dynamics) optimised tubing and wider tyre clearance.

“Impressed by our involvement with the Standert race workforce, we got down to create a quicker aluminium body, pushing each materials and manufacturing limits,” stated Maxe Faschina, Head of Product at Standert.

Like its predecessor, it’s handmade in Italy utilizing Dedacciai’s scandium tubing. Standert selected the fabric for its spectacular stiffness to weight ratio, with the Kreissäge RS benefiting from customized drawn tubing. Whereas there’s no claimed weight within the advertising materials, when we reviewed the earlier version of the bike we have been advised {that a} dimension 54 tipped the scales at 1,470g plus 430g for the carbon fork; our check bike in a dimension 56 weighed 8.6kg.

“The Kreissäge RS has at all times been about defining our personal requirements,” says Max Von Senger, CEO and Founder at Standert. “It’s about displaying what steel bikes can do, about being completely different in a sea of black plastic, and about having enjoyable, whereas placing within the arduous work. The brand new RS doubles down on what made the Kreissäge an important bike within the first place, whereas marking an enormous step in our quest to make the perfect steel race bike on the market.”

Provided that it is a bike designed for racing then, it is smart that Standert has invested time, cash and energy in bettering its aerodynamic efficiency. To do that it’s used CFD to create a set of aero tube shapes. Most notable, when in comparison with the outgoing mannequin, is the far slimmer and now hourglass-shaped head tube. Nevertheless, the highest tube, head tube and seat stays have additionally been created to cut back drag and save watts. The highest tube is now sloping, which ought to add in a little bit of further compliance provided that extra of the seat put up will now be uncovered. Regardless of these modifications, the Kreissäge RS retains its traditional appears to be like

Additionally retained is the body’s compact geometry that’s designed to make it quick and agile; the smaller triangles add stiffness, whereas each the stack and attain ought to lead to a fairly lengthy and low using place. For reference a dimension 54 has a stack top of 549mm and a attain of 387mm, whereas the chainstays measure 410mm.

As earlier than the Kreissäge RS totally built-in cable routing, aiding the bike’s aerodynamic credentials. This time round there’s inside headset bearings too, which ought to assist cut back weight and enhance longevity, with fewer providers wanted.

Various updates counsel a futureproofing of types. The threaded T47 backside bracket is a holdover from the earlier mannequin however is turning into the accepted customary for street bikes. Clearance has been elevated to accommodate 35mm huge tyres, which permits for the frameset to profit from tubeless wheels with wider inside rim widths in addition to the broader tyres themselves. Like many manufacturers, Standert has adopted the UDH (Common Derailleur Hanger), which just like the T47 BB is turning into the norm.

Construct choices for the Kreissäge RS embrace Shimano Dura-Ace Di2 and Shimano Ultegra Di2 groupsets in addition to Sram Crimson Axs and Drive AXS, with both DT Swiss Arc 1400 wheels or a set from Scope. There’s additionally a alternative of a Polymer Sculpture carbon cockpit and Polymer Obelisk carbon seatpost, or the model’s Fortunate Cat bars and put up.
