Yes, you read that right. Newmens new aero carbon 48mm-deep Streem G.48 gravel wheels come in three wheel sizes, two of which you dont even have a bike big enough for just yet! We already knew they were making 32 carbon gravel race wheels when we saw the carbon-spoked G.62 raced to a UCI win in Girona available for a few weeks now.But taking it to another level now, this lower profile and lighter mid-depth all-rounder G.48 gravel wheelset includes not just the traditional 28/700c size and a newer 32 option, but also the inbetweener 30.5 / 750d size that I test-rode two summers ago.Newmen Streem G.48 & G.62 aero gravel wheels in all sizesStreem G.62 32 on race-winning Avona Callis 32 (Photo/Cory Benson)Newmen is quickly expanding their gravel wheel range. A few weeks back, they officially added a 32 option to the 62mm-deep, 27mm internal G.62 family that debuted over the summer, and at no extra cost. (Photos/Newmen)Now, theres a shallower 48mm-deep, 27mm internal G.48 for more hilly riding and gravel racing. Its quite a bit lighter. And with an outer width & depth similar to commonly used 45-50mm gravel tires, it should be quite a solid aerodynamic performer while offering good low-pressure comfort.First, the G.48 will come in conventional 28 (thats what Germans like to call 700c). But hot on its heels, Newmen promises both 32 versions AND the middle size 30.5 / 750d that we almost thought had disappeared. Until a Cube rider raced 30.5 at the Enduro World Champs less than a month ago. Newmen calls the multi-size concept: The right size for everyone. (Eds.: Just not 650b.)The introduction of 30.5 is particularly noteworthy, as this wheel size is still relatively unfamiliar within the gravel segment. With this expansion, Newmen is responding to the growing interest in larger wheel sizes and offering riders more choice across its gravel range.Streem G.48 Tech Details48mm rounded aero carbon gravel rimwide 45mm outer width, aerodynamically optimized for modern 45-50mm gravel tires27mm hooked tubeless inner width, designed to preserve tire shape/size21 Vonoa Aero Wide Carbon spokes on both the front and rear wheels, or24 Sapim CX-Ray bladed stainless steel spokes front & rear (for a 17.7% cost savings)Newmen Fade R CNC-machined centerlock disc 12mm thru-axle, 3-pawl 36T / 10 hubshand-built wheelsets available with Shimano HG or SRAM XDR freehubs (N3W & MicroSpline available separately)carbon-spoked wheels are built in Germany, steel-spoked wheels are built in Czechiaincludes Newmen hidden Aero Valve System & tubeless-ready: taped for tubeless, with valves & sealant!compatible with both hidden Aero Valve AND conventional tubeless valvestested to XC MTB wheel standards, rated up to 130kg rider+bike system weightwheelsets from 1400g (claimed with carbon spokes), or 1550g (with bladed steel spokes)Streem G.62 Details28 G.62s on a Rose Backroad FFdeeper 62mm aero carbon gravel rimsame 45mm outer width, aero-optimized for big gravel tiressame 27mm hooked tubeless inner widthalso available with 21 Vonoa Aero Wide Carbon spokes, or24 Sapim CX-Ray bladed stainless steel spokeswheelsets from 1530g (claimed with carbon spokes), or 1600g (with steel spokes)32 & 30.5 Details12x110mm Boost hub on race-winning Avona Callis 32 (Photo/Cory Benson)same G.48 & G.62 rim profilesRoad Boost 12mm centerlock hubs for added stiffness on the larger diameter rimssame aero carbon & steel spoke optionsalso XC MTB tested, rated to 130kg rider+bike system weight32 wheelsets from 1670g (claimed with carbon spokes)Newmen Streem G.48 & G.62 Pricing, options & availabilityBoth the newest Newmen Streem G.48 & the G.62s that came out this summer are available with either Vonoa bladed carbon spokes or Sapim bladed stainless steel spokes. Pricing is also the same for both rim depths 1690 with carbon spokes, 1390 for stainless spokes. And you can even pick from low-key black on carbon decals, or flashy silver logos.Streem G.48 700c & G.62 32Today, both rim depths are available in the traditional 700c/28 wheel diameter with carbon spokes to buy right now. The G.62 is also available now in 28 with steel spokes, plus the bigger 32 diameter in both carbon or steel spoke versions. The new G.48 with steel spokes will come in spring 2027. Thats also the assumption for 32 G.48 or 30.5 versions of either. Newmen has not yet shared an official availability date for these new sizes, beyond stating that Both the Streem G.48 and Streem G.62 will be available in 28, 30.5, and 32 in the future.Newmen-components.de
