Newmen Streem G.62: Aero-carbon wheels now available in 32 inches

​Newmen is launching its top-of-the-range gravel racing model, the Streem G.62, in a new 32-inch size. Despite the larger diameter, the carbon wheelset weighs 1,670 grams. Newmen has also announced prices; however, for the time being, the new wheels will be supplied exclusively to bicycle manufacturers.

​The The debate over 32 inches is launching its first specific production model: Newmen is adapting its deep-profile gravel racing wheel, the Streem G.62, to the larger wheel format with a 32-inch (686-millimetre) rim diameter. The dimensions of the rim profile remain unchanged from the familiar 28-inch version: a 62-millimetre height, combined with an outer width of 45 millimetres and an inner width of 27 millimetres.

Two versions are available. The Streem G.62 CS has 21 Vonoa carbon spokes and, according to Newmen, weighs 1,670 grams per set. The more affordable version, with 24 Sapim CX-Ray steel spokes, weighs 1,760 grams.

Newmen is banking on Boost

One of the most significant changes, apart from the diameter, is the axle spacing: Newmen uses 12 × 110 millimetres at the front and 12 × 148 millimetres at the rear for the 32-inch wheelset. This marks the introduction of the Boost standard – familiar from the mountain bike sector – to gravel road bikes.

The greater flange spacing is intended to compensate for the structural disadvantage of the longer spokes. According to the manufacturer, this enables the 32-inch wheel to achieve a similar lateral stiffness to the smaller G.62 version. At the same time, Newmen is able to do without additional or heavier spokes. Weighing 1,670 grams, the carbon version is only 140 grams heavier than the corresponding 28-inch model.

Unmodified aero rim profile with hooks

Although the rim diameter has changed from ETRTO 622 to 686 millimetres As it grows, Newmen is taking on the profile of the well-known Streem G.62:

• Rim height: 62 mm
• External width: 45 mm
• Internal width: 27 mm
• Wheel rim material: Carbon
• Wheel type: Hooked and Tubeless Ready

The rim is designed for modern gravel tyres between 45 and 50 millimetres wide. The large outer diameter is intended to create as smooth a transition as possible between the tyre and the rim. This allows the airflow behind the tyre to re-establish contact with the rim.

At 27 millimetres, the inner width is deliberately set significantly narrower than the maximum outer width. Newmen aims to strike a balance between tyre support, aerodynamics and comfort. A wider inner width would cause the tyre to spread out more, which, according to the manufacturer, would reduce its inherent damping.

Despite the rim’s height of 62 millimetres, Newmen promises excellent crosswind stability. To achieve this, the rim features a distinctly bulging profile, which is also designed to provide a degree of vertical flex and thus additional comfort.

Newmen has retained the hooked rim design for its new 32-inch model as well. The hooked design is intended to provide additional grip and safety, particularly at higher tyre pressures. The maximum permissible system weight is 130 kilograms.

With carbon or steel spokes

The new Streem G.62 is available in two versions:

Streem G.62 CS

• 21 Vonoa carbon spokes
• 1,670 g per set
• RRP: 1,690 euros

Streem G.62 with steel spokes

• 24 Sapim CX Ray
• 1,760 g per set
• RRP: 1,390 euros

At the centre is the Newmen Fade R hub, featuring three pawls and a CentreLock brake disc mount. Freewheel bodies are available for Shimano HG, Shimano Micro Spline and SRAM XDR. Both versions are compatible with Newmen’s internal Aero Valve System. According to the data sheet, an Aero Valve and tubeless sealant are included in the scope of delivery.

Not available for general sale at present

Although Newmen has already announced recommended retail prices of 1,690 and 1,390 euros respectively, the 32-inch wheels are initially set to be available exclusively on the OEM market. This means that, for the time being, they will only be offered as original equipment on specially designed complete bikes.

Newmen has not yet revealed which bicycle manufacturers will be the first to use the Streem G.62, nor when the first production bikes fitted with it will be released. The wheels were showcased on a carbon gravel bike from the Avona brand.

First racing victory at Sea Otter Europe

The well-known 28-inch version of the G.62 has already secured a victory at The Traka gravel race, amongst others. According to Newmen, the new 32-inch model has also got off to a winning start: Leon Kaiser rode it to victory in the UCI race held as part of Sea Otter Europe.

Kaiser cites improved roll-over behaviour and better cornering grip as the key advantages of the larger format. On fast and uneven gravel sections in particular, the larger wheel diameter is said to enhance speed and riding stability.
