Lightweight’s Urgestalt demonstrated that the company could apply their approach to wheels to framesets. The rim brake version is light, stiff, efficient, and can go all day. This new Disc Frameset refines the concept by making the bike more comfortable and able to run bigger tires, meaning it is not only an able road racer, but capable of going beyond the road, be it cobbles, gravel, or dirt.
Lightweight’s mission is to build the lightest, strongest, best-engineered pro-level components on the market. Their wares set the standard for carbon-fiber wheels, but their obsessive attention to detail and precision lay-ups requiring extensive labor from skilled artisans price their components beyond what pro teams can deal with. As a result, they set standards beyond industry norms, a benefit to those who ride Lightweight.
This is a road racing frame that can be ridden all day in all conditions on all road surfaces. It is stiff and fast enough for crits, stable and compliant enough for gran fondos, and everything in between. The geometry is fairly traditional, with a decent bottom bracket drop, a head tube height that is neither tall nor short, and angles that just about everyone can find stable, fast, and comfortable. They’ve lengthened the chainstays slightly compared to the rim brake version to accommodate both the disc brakes utilizing the flat mount standard and tires up to 28mm in width. They’ve also shortened the seat tube length and removed the brake bridge between the seat stays. These two features add vertical compliance to the frame. The final piece in the compliance puzzle is the 27.2mm round seat post that the frame works with. The diameter and extra length adds vibration-damping to the frame.
These design choices are in addition to the design choices already in place for the Urgestalt rim brake version. They started there with size-specific lay-ups. They also utilized the fiber-orientation of the carbon plies, laying them up in alignment with the forces that the road generates for greater comfort, and in opposition to the forces that pedaling and standing on the pedals produces for greater efficiency. The fork has also been designed with the forces it faces in mind. The carbon plies have been laid up to resist the braking forces generated by the disc caliper as well as resist lateral movement when out of the saddle and turning, while still allowing for vertical flex to better deal with rough roads.
Helping with tire fit and stiffness are the choices for the bottom bracket and wheel retention. The bottom bracket standard is BB386 EVO, which provides a wider, taller shell and gives you more crank choices than BB86. The wheels are secured by thru-axles, 100x12 in front and 142x12 in back. The flat mounts accommodate rotors up to 160mm in diameter. To keep the frame light and strong, they use a front derailleur hanger. The cables run internally and support, mechanical and hydraulic braking as well as mechanical, hydraulic, and electronic shifting. The steerer tube is a tapered 1 1/8” to 1 1/2”.
As with the rim brake version, and all their stuff, the Urgestalt Disc is bleeding edge light, but still strong enough to pass European and UCI safety standards. Weight for the 54 is 800g for the naked frame, 850g including clamps, and the like. The fork weighs in at 375g. As with many an ultra light bike, the Urgestalt Disc has a weight limit. It’s impressively heavy: 120kg for rider and componentry.
The frameset comes with: headset, top cap, spacer kit, compression plug, cable guides, plugs, and stops, derailleur hangers, seatpost clamp, and thru-axles.
The Lightweight Urgestalt Disc brings the Lightweight frameset to an even wider range of rides.
