Strong and lightweight: the Direttissima Disc Brake by Trickstuff
Can you improve upon a legend? Nothing less than really high braking power, excellent dosing, full stability and perfect haptics were the basic requirements for this brake - the successor of the famous CLEG.
The term " Direttissima" comes from Alpinism and refers to the direct, straight line up to the summit and back down again. And it is precisely for these requirements that the Direttissima is designed.
The slim appearance of the brake pump combined with a compact but ultra-stiff four-piston caliper results in a lightweight yet powerful brake.
A prototype of the Direttissima has already successfully guided the Czech bear Tomas Zejda down the steep gorges of the Rampage. With one finger it is possible to master the steepest descents without cramping forearms and then enjoy the trail again or rip the next backflip in Utah.
Friction in the system is the enemy of good dosing. Internal friction has been minimised by the consistent use of roller bearings, which have no friction due to their principle, and by the use of PTFE elements at the contact points between the encoder piston and the pump housing. Static and sliding friction of PTFE are equal, but above all extremely low, which results in an extremely sensitive dosing.
Nothing disturbs and annoys the finger rest as much as corners and edges. Therefore, the Direttissima has none of these at the only two brake-to-rider contact points. A surface form created in several iterations and produced with specially manufactured milling heads ensures braking without pressure points even after kilometres of descent. The finger rest is also free of annoying friction points such as holes, grooves or depressions. Not the brake lever should tame the finger - the finger should tame the lever. In the natural movement of braking, the finger slides over the brake lever as the lever approaches the handlebars. This should be supported by a smooth surface and not prevented by static friction. This means that the hand does not have to turn to compensate - the handlebars now remains firmly in your grip.
Intuitive operation is one of the main criteria of a good brake. A wooden and stiff or a squishy soft pressure point is always a hindrance. The trick was to fine-tune the master and caliper cross-sections and kinematics so that the pressure point was stable and firm, but not rigid and wooden. Due to the increased overall transmission ratio compared to the predecessor, a crystal-clearly defined but pleasantly elastic pressure point could be achieved. The characteristic " dong" of the CLEG brake can still be felt on the Direttissima, but the behaviour at the operating point is now even more intuitive, lively and power-saving.
Do curves only exist for suspension forks and rear shocks? Far from it - a brake also has a characteristic curve. The mechanical actuation of the connecting rod produces a change in angle when pulling and thus, in this case, a progressive brake force characteristic. The harder you pull, the higher the braking force - and disproportionately so. After long braking sessions, do your forearms become flabby at some point? Do you feel like you have to pull harder and harder on the lever? The carefully chosen, slight knee lever effect in the lever mechanism ensures an increasing transmission ratio the harder you pull on the lever. Slackening of fingers and forearm is a thing of the past, thanks to old-fashioned pure mechanics!
The slim and elegant handlebar clamp on the CLEG has been rethought for the Direttissima, and consistently reduced to tension and compression. The two-piece design compensates for deviations in handlebar circumference. This creates an extremely large contact surface that encloses the handlebars almost 360° and does not pass on any notch or point loads to the handlebars. This predestines the Direttissima especially for sensitive carbon handlebars, which should be clamped as gently and extensively as possible. The wide support effectively prevents " bending" of the brake lever under strong lever pull. This stiffens the pressure point and makes braking feel even more direct.
