Toot Harper bunch bars 2027

Why Track Handlebars Needed Rethinking Traditional track handlebars force compromise. You choose stack and reach based on stem length and angle, then adapt your position to what the handlebar allows. Wrong order. 2027 regulations introduced width limitations that further constrained design options. Most manufacturers responded by simply narrowing existing geometries. We saw an opportunity. What if the handlebar adapted to the athlete instead of the other way around? A patented solution to improve control and stability HARPER's patent-pending parametric system allows continuous adjustment of hand position relative to stem clamping area while maintaining structural integrity and safety without connection bolts and aerodynamic efficiency. How it works: The BWS design - necessary for madison grip - becomes a parametric element. Distance between upper and lower planes can be optimized per athlete without changing stem size or angle. Result: Same stem geometry fits multiple positions Stack and reach independently adjustable Maintains consistent structural characteristics FULLY UCI COMPLIANT 2027 VERSION AVALABLE Fight for your minds. 2027 UCI legal track handlebars. A parametric patented design made in carbon fiber or 3D printed. Another radical revolution by TOOT Engineering team for those chasing dreams and wanting to make them real. The Boxes The cockpit which comprises the handlebar and the stem must be able to fit entirely within the template formed by five rectangular boxes and the compensation triangles as shown by the diagram. The boxes must be placed in the plane orthogonal to the axis of the steerer tube, passing through the highest point of the stem. Within the rules, beyond the limits. HARPER designed for UCI 2027 track handlebar regulations (Article 1.3.022). Key requirements: Box geometry constraints (5-box template) Width limitations Cross-section dimensions (10mm minimum) Multiple elements configuration (max 2 elements as allowed in rules) HARPER meets all dimensional and geometric requirements as written in regulations. Compliance drawings available for technical review The sections In addition, all handlebars must conform to the following: - The maximum dimension of the cross section of the handlebars is 80 / 65 mm for track, - The maximum dimension of the cross section of the stem is 80 mm - The minimum dimension of the cross section of all fork accessory is 10 mm - Two isosceles compensation triangles with two 40 mm sides are authorised at the joints between the stem and the handlebars. - The minimum overall width of handlebars, measured from outside to outside, is 350 mm for track - The maximum dimension from the external extremity of the handlebar and the internal extremity of the same side of the handlebar shall not exceed 80 mm for track. Multiple elements are authorized for the stem, the traditional handlebars and base bars. Individual tubes and multiple tubes have to respect the maximum permitted section dimension of the area and the minimum section dimension of 10 mm. The multiple elements rule applies in the same areas than the rule of the minimum and maximum dimension for the tubes. In the case of the traditional handlebars if one of the sections comprises multiple elements (not greater than 2), each element taken individually have to respect the maximum and minimum dimensions authorised in any direction. The requirement for the elements to respect the maximum and minimum dimensions in any direction in conjunction is not required. Control Where It Matters HARPER development began with fundamental research question: what makes a handlebar stable? Designed by Romolo Stanco staff HARPER was developed and engineered with world class athletes. Research Partnership: University of Pavia Multi-year collaboration with CompMech Laboratory (Prof. Ferdinando Auricchio) studying handlebar stability, control response, and rider interface dynamics. Key findings: Handlebar stability is a balance between stiffness, geometry, mass distribution, and how forces transfer through rider contact points. Traditional design assumptions don't hold under narrow-width constraints. HARPER application: Parametric system allows optimization of stability characteristics independent of fit requirements. Athlete gets their position AND optimal control response. Laboratory verification: Testing protocols conducted at University of Pavia. Professor Auricchio: "The parametric approach allows us to optimize variables that were previously locked together."
