Description

The HOPE RX40 700C PRO 5 Straight-Pull 12x100 mm front wheel pairs the RX40 carbon rim with a Pro 5 Centerlock straight-pull hub. The complete wheel is designed and assembled by Hope in Barnoldswick, England. Built for fast gravel riding and mixed road-and-trail outings, its 40 mm profile provides a genuine aerodynamic benefit while remaining manageable in crosswinds, where deeper rims can become a handful on exposed sections.

The hookless rim measures 25.5 mm internally and 30 mm externally, making it well suited to today’s 32–60 mm gravel tyres set up tubeless. It comes pre-taped, with a Hope Presta valve matching the hub colour. The 24 Sapim CX-Ray bladed spokes provide the lateral stiffness needed when accelerating without adding unnecessary weight: the claimed front-wheel weight is 685 g.

The Pro 5 hub uses Hope’s own pawl mechanism, with a 54-tooth ratchet ring and six offset pawls providing 108 engagement points, or 3.33° between engagements. The bearings can be replaced, and most wear parts remain available individually, making long-term wheel serviceability one of the brand’s key strengths.

Wheel sold individually, with a Centerlock disc mount.

Frequently asked questions

Which tyres can I fit to a HOPE RX40 hookless rim?

The RX40 rim is hookless: it requires a tubeless tyre explicitly approved for hookless rims, with a width of 32 to 60 mm. Avoid tyres intended for use with inner tubes and tyres whose manufacturer does not confirm this compatibility, because on a hookless rim the bead is held in place solely by internal pressure.

The 25.5 mm internal width works best with 40 to 50 mm tyres, which will have an actual width slightly greater than their stated size. Probikeshop specifies hookless compatibility on the listings for the relevant gravel tyres.

What pressure should I use for a tyre on a hookless rim?

A hookless rim has a lower maximum pressure than a hooked rim, and the lower of the rim’s and tyre’s limits always applies. Consult the Hope instructions supplied with the wheel and the tyre manufacturer’s recommendations before inflating.

In practice, gravel tyres 40 mm and wider are generally run well below these limits. Exceeding them is mainly a concern with narrow tyres inflated to road-bike pressures.

Does the wheel come ready for tubeless setup?

Yes. The rim comes from the factory already taped, and a Hope Presta valve matching the hub colour is supplied with the wheel. All that remains is to fit the tyre and add sealant, which is not included.

Allow around 60 ml of sealant for a 40 to 45 mm gravel tyre, and use a high-volume air source (a compressor or reservoir pump) to seat the beads on the first fitting.

Can I fit a 6-bolt rotor to this wheel?

This wheel’s Pro 5 hub has a Centerlock mount: a Centerlock rotor fits directly using a cassette lockring tool. To reuse an existing 6-bolt rotor, you need a Centerlock-to-6-bolt adapter that screws onto the hub.

In that case, check clearance at your brake caliper: on some setups, the adapter shifts the rotor slightly outwards.

What’s the difference between a HOPE Pro 5 hub and a Pro 4?

The Pro 5 succeeded the Pro 4 in Hope’s range. It has a 54-tooth freehub with six offset pawls, giving 108 engagement points and 3.33° between engagements, compared with 44 engagement points on the Pro 4. In practice, pedalling picks up much more quickly, which you can feel when accelerating on trails or putting the power down after a technical section.

Is the HOPE RX40 front wheel sold individually or as a pair?

This wheel is sold individually. To make a complete pair, match it with the HOPE RX40 700C PRO 5 rear wheel in the same hub colour, choosing the axle spacing (12 x 135/142 mm or 12 x 148 mm Boost) and freehub body to suit your bike.

Selling the wheels separately also means you can replace just one wheel if it breaks, or mix front and rear axle standards.
