This is for some newly hand built 29 inch 700c gravel bike wheelsets incorporating brand new black 32 hole DT Swiss G540 db disc rims, and brand new black Bitex BX601F front Lefty 50 and MTR12 rear, 6-bolt disc specific hubs. After extensive testing DT Swiss have settled on a full 24mm as the perfect width for modern Gravel bikes. The added width gives better support to wide, 35c or larger tyres, allowing the use of lower pressures, enhancing grip & comfort whilst reducing rolling resistance & tyre flex under cornering. Robust, sleeved construction gives a great value package for a wide gravel rim with a suggested maximum system weight of 130kg. The rims can be used with or without tubes. The black anodised and polished, sealed bearing, Bitex BX601F and MTR12 hubs weigh just 410g and are ideal for road, gravel, and XC. The hubs are set for 100mm Lefty 50 and 142mm x 12mm thru axles. The BX601F Lefty 50 will fit Lefty Oliver, Lefty 2.0, Supermax, and all older Lefty (2001-2014). Choose between a standard 12 speed Shimano HG freehub, SRAM XDR driver, or SRAM XD driver. The rims are 3-cross laced to the hubs with Sapim Leader silver stainless steel spokes and nickel plated brass nipples. These beautiful wheelsets have been hand trued, dished and spokes tensioned according to rim manufacturers recommendations.
