Components

Tyres

- Schwalbe is launching the 32-inch G-One RS Pro and RX Pro gravel tyres in 50-686 and 55-686 sizes, available from April 2027, including matching inner tubes.  
- The 32-inch size promises improved roll-over behaviour, stability and comfort, but requires new frame and suspension designs and adds weight.  
- The 32-inch format is not yet a standard; systems and the supply of parts are still in their infancy; market success depends on component manufacturers and production bikes.

Schwalbe G-One: 32-inch tyres for gravel bikes

- From the 2027 model year onwards, Cube will be fitting almost all new bikes with Schwalbe inner tubes featuring the Clik Valve, thereby setting a new industry standard.
- The Clik Valve makes inflating easier without the need for screws or levers, though it requires a special Schwalbe pump head for maximum convenience.
- The valve promises a higher air flow rate, but tests show only minor advantages over the SV valve; Cube is supplying compatible ACID pumps to facilitate the switch.

- A hookless carbon rim with a 30 mm internal rim width accommodates wide gravel tyres from 47 mm (and in some cases from 40 mm) for greater volume and lower pressures.
- A 45 mm rim height, a weight of 1,240 g and predictable crosswind behaviour are designed to ensure agile handling on technical, varied terrain.
- SAPIM-CX carbon spokes, 2:1 lacing pattern, PRO hubs, various freehub options; price from €1,599, available from 28 August 2026.

- Marathon Almotion Pro: a fast, comfortable touring tyre with Addix Race compound, tubeless-ready, low rolling resistance and good grip  
- Suitable for trekking, all-road and gravel bikes with a minimum tyre clearance of 40 mm; Weight 530 g (40 mm), price approx. 80 euros RRP  
- Strengths: quiet ride, high cornering confidence, puncture protection; Weaknesses: high price, no widths under 40 mm, some maintenance required for tubeless use

- Silca is entering the tyre market with its Protocol range, offering three gravel tyres and one road tyre designed for modern, wide rims.  
- Design features: high volume, 120 TPI casings, ‘Pulsar’ compound, carbon bead and an ‘inverse proportional design’ optimised for low air pressures.  
- The range covers everything from fast gravel races to muddy and cobbled terrain; the RRP is 119 euros per tyre, placing it at the upper end of the price range.

Silca launches its own range of tyres for gravel and road cycling: a tyre revolution?

- Continental is launching a 32-mm version of the Aero 111 front tyre for greater volume, comfort and control on rough roads.
- The Aero 111 remains an aerodynamically optimised, tubeless-compatible performance tyre featuring a BlackChili compound and Vectran breaker, RRP €128.95.
- The tread pattern, featuring 48 vortex generators, was developed in collaboration with Swiss Side and DT Swiss to deliver efficient aerodynamics across a range of approach angles.

Aerodynamics meets comfort: the Continental Aero 111 is getting even wider

- Tubeless gravel tyres 40–45 mm wide with an all-round tread pattern offer the best balance of speed, comfort and puncture protection for most riders.
- 40 mm tyres are suitable for fast, mainly tarmac-based rides; 45 mm for mixed terrain and heavier riders; and 50 mm for rough terrain, luggage or high rider weight.
- Handling is determined by the overall combination of width, tyre pressure, carcass, tread pattern, rubber compound and whether the tyre is used tubeless or with an inner tube.

- Schwalbe Motion Kojak: an affordable everyday tyre with low rolling resistance, quiet running and reliable puncture protection thanks to RaceGuard.
- The scalloped tread pattern and ADDIX Green compound ensure a predictable ride feel, good grip on tarmac and light gravel, as well as greater sustainability.
- Limitations: available only as a clincher tyre, not tubeless; minimum width 40 mm; wet grip still unclear; some of the brand’s own range offers greater versatility.

Review of an affordable everyday tyre from Schwalbe: What can the new Motion Kojak do?

- 35–40 mm: fast and efficient on tarmac, cycle paths and well-compacted gravel, but less comfortable due to higher tyre pressure.  
- 42–45 mm: versatile all-round range for forest, field and gravel tracks as well as tarmac; a good balance of speed, comfort and control.  
- From approx. 47 mm: Focus on off-road riding with more cushioning, grip and safety; rolling resistance depends heavily on tyre pressure, tread pattern and surface.

Tyre width for gravel bikes: How wide should the tyre be?

- Tubeless tyres offer lower rolling resistance, greater puncture protection and allow for lower tyre pressure, resulting in greater comfort and grip.  
- Sealant should be checked every 2–3 months, topped up if necessary, and completely replaced if it has dried out or if the components have separated.  
- Do not mix different types of sealant; ideally, inject it using a syringe via the valve or directly into the partially fitted tyre.

Tubeless bliss: the best tubeless tips from the expert

- Oko markets its own brand, Magic Milk, and offers several sealants for tubeless and clincher tyres.  
- According to the manufacturer, Tubeless-Pro Hi-Fibre seals cuts of up to 8 mm, whilst the more affordable Original seals cuts of up to 6 mm; both have a shelf life of around 6 months.  
- Innertube Sealant for inner tubes is available in Hi-Fibre, Original (Tubolito-approved) and organic versions, all of which are ammonia-free and come in a well-designed bottle.

Oko Magic Milk: A sealant for tubular riders too?

- Maxx Seal is compatible with CO₂ and inserts, and is available in recycled PET bottles (250 ml, 500 ml, 1 l) as well as in 5-litre canisters.
