2018 Passoni Top Evolution
The Passoni Top Evolution has been developed with endurance riders in mind. It mixes and matches the two grades of titanium Passoni rely on for most of their frames, and then combines them with a slightly more relaxed geometry for the five stock sizes, while of course still offering custom geometry for anyone who wants to have precisely the perfect setup.
A Gran Fondo is a great event and super fun do ride, but it is very important that you be comfortable enough on your bike to grind out the miles hour after hour. Nearly any bike can be comfortable enough for an hour or two of riding. It’s when the hours stretch into four, five and six that bike comfort, fit and geometry really start to matter. The Passoni Top Evolution makes use of grade 9 titanium for most of its tubing, which means that the frame builder can draw it to thicknesses in order to offer the desired level of rigidity without losing that comfort level after six hours on a bike. Grade 9 means that the ti contains 3.0% aluminum and 2.5% vanadium that allows them to find that perfect mix between an easily weldable material and a super strong alloy. Then the head tube, bottom bracket shell and dropouts use grade 5 titanium which is 6.0% aluminum and 4.0% vanadium, making it super strong for those high force areas, and is extremely resistant to corrosion, which will keep your Top Evolution in top condition for many years, even if you often find yourself riding through rainy conditions.
Aside from comfort, confidence in the handling will sit high on the list of must-haves for any endurance oriented bike. The Top Evolution uses a 1"1/8 head tube and then will give you the choice between a Columbus Grammy Slim or Columbus Tusk Straight fork, both customized for Passoni. Both are monocoque carbon, but with the Grammy Slim you’ll get a 43mm rake while with the Tusk Straight you’ll have 45mm. And with the Grammy Slim you’ll save a touch of weight since it comes with carbon dropouts while the Tusk Straight uses aluminum. In any case, both fork options will give you a comfortable ride quality with pristine handling.
Additional options you can choose to have with the Passoni Top Evolution include electronic groupsets, internal rear cable routing and shell shaped dropouts. The pure titanium appearance of the tubes is only enhanced by the 20+ hours of hand polishing each frame receives in addition to finely sandblasted graphics. It is definitely a beautiful bike intended to impress on the road as well as off it.
