Lightweight construction used to be a premise in road bike construction and German carbon experts were leaders in this field. However, with the advent of disc brakes, aerodynamics and integration, these innovative developers lost influence. Now two former leading brands are looking to demonstrate how light road bikes can be today with their modern complete bikes. We have tested the Benotti Fuoco Carbon Ultra and the Schmolke Leggerissima TLO. Here is the test of the Schmolke Leggerissima.

Saddle and support

The post with classic yoke clamping has hardly changed over the decades, and at 90 grams it is still a benchmark in terms of weight today: mass-produced carbon posts easily weigh twice as much. The Schmolke seatpost also flexes extremely well, comparable to the suspension capacity of the best marathon racing bikes. The saddle is also a breath of fresh air: the one-piece carbon sculpture weighs just 57 grams. It is also surprisingly comfortable, although the slippery surface can be annoying.



Handlebars and stem

Handlebars (approx. 140 grams) and stem (approx. 80 grams) are Schmolke's speciality, there are no lighter components. However, titanium bolts and sensitive clamping points require a careful tightening hand. With an expander made of special foam and a carbon Ahead screw, the last gram was also extracted from the small parts.

The carbon crankset from THM (603 grams including chainrings) saves a good 150 grams on the Shimano groupset, while the carbon chainrings from Carbon-Ti shift perfectly. A power meter is included. Otherwise, Schmolke refrains from experimenting with the drivetrain and brakes. The brake tuning with Trickstuff discs not only saves a few extra grams, the discs also respond better than the Shimano discs.

Frame and fork

Schmolke does not manufacture the frame set with transparent blue paint itself, but in co-operation with a South Korean frame manufacturer. Weighing in at 786 grams (fork: 341 grams) with decent stiffness, the weight is impressive; however, lightweight frames from major brands such as Giant TCR, Cervélo R5 or Trek Émonda are lighter. The set is also available for self-assembly for 5500 euros.

Wheels and tyres

The in-house rims of the TLO wheels, manufactured using the prepreg process, are significantly lighter than the Schmolke rims using the braiding process. With carbon spokes and hubs from Extralite, they add up to a "naked weight" of less than 1000 grams - for the front and rear wheel. Including the cassette, brake discs and tyres, the set weighs just under two kilograms.
