Dial in the perfect time trial position with Profile Design's T4 Carbon Clip On TT Bars. The bars feature a traditional ski bend shape with a shallow angle between the extension and the shifters. This offers a neutral wrist angle with a low extension height for optimal aerodynamics. Profile Design includes its J4 bracket, which is controlled by a single bolt and allows you to easily adjust extension length and rotation. The T4 bars are completed with F 35 armrests, which feature 3x foreaft positioning. The F 35 offers you 30mm of adjustment and allows for 15 degrees 7. 5 degrees of rotation adjustment, so you'll have no problem finding the ideal fit. The Profile Design T4 bars are compatible with both 31. 8mm and 26. 0mm bars with included shim.
