Description
The HOPE RX40 700C PRO 5 Straight-Pull 12x148 mm Boost rear wheel pairs the RX40 carbon rim with the Pro 5 Centerlock straight-pull hub, designed and assembled by Hope in Barnoldswick, England. Together with the RX40 front wheel, it makes a versatile gravel wheelset suited to both fast road sections and smooth trails.
The 40 mm-deep hookless rim measures 25.5 mm internally and 30 mm externally, making it suitable for 32 to 60 mm tyres set up tubeless. It comes pre-taped with a Hope Presta valve matched to the hub. The 24 Sapim CX-Ray bladed spokes maintain stiffness under torque despite the rear wheel’s pronounced dish, at a claimed weight of 838 g.
This version has 12 x 148 mm Boost spacing, found on gravel bikes with extra-generous tyre clearance and frames derived from mountain bikes. The Pro 5 hub has a 54-tooth freehub with six offset pawls, providing 108 engagement points and 3.33° between engagements for immediate pedal pickup. Choose the freehub body to suit your drivetrain — Shimano HG, Microspline or SRAM XDR — from the available variants; it can also be removed later.
