The Reserve 40|44 Wheelset carbon road disc brake concept employs a shallower, wider front wheel for greater stability and control, along with a taller, narrower rear wheel for better aerodynamics, speed, and power transfer. And it’s designed to provide a comfortable, safe ride all day long, even if you hit it a rough patch of road or encounter an occasional short gravel-strewn side road, alley or driveway. The 40|44 was conceived via CFD and wind tunnel development, in conjunction with expertise from Cervelo. Pro cycling specific requirements and proper aerodynamic considerations and applications were applied to maximize the conceptual purpose of the 40|44 wheelset as a great all-rounder, especially on hilly or and moderately flat or variable terrain where more responsive wheels that still carry an aero advantage ensure the ability to carry speed at all times in a group or solo riding situation.

DT Swiss supplies the fast responding, incredibly reliable, wonderfully easy-to-service and truly lightweight DT Swiss 240 Center Lock disc hubset for this version of the 34|37 wheelset. There may not be a hub as easy to work on and manage than the DT 240, nor has there been one for years. The 240 has been upgraded and refined without losing it's pure functionality and simple serviceability. The low profile straightpull flange design and wide bearing placement keep the spoke tension high and the thru-axle hub interface incredibly stout, regardless of weight. The use of Sapim CX-Ray Aero straightpull spokes allows for very high tension overall, excellent power transfer, lateral stiffness, and some rim and rider forgiveness. External nipples are used for easy true/tension with this 24 hole (front and rear) set-up with 2x/2x lacing all-around. The hubs are built for thru-axle use, with a 12/100mm front and 12/142mm rear configuration to go along with the Center Lock disc rotor interface. The drive system on the rear hub is the 36T EXP Ratchet, an improvement on the previous generation along with a reduction in weight. With exceptional reliability and engagement, DT's own steel cartridge bearings and superior seals, the 240 equipped,1388 gram 40|44 wheelset delivers exceptional protection from the elements and smooth running long life.
