Newmen Promises Three Wheel Sizes. You Can Buy One.
Newmen's Streem G.48 gravel wheels: 48mm deep, 27mm internal, 1400g, and three wheel sizes — but only one you can actually buy today.
Three hundred euros. That's the gap between the carbon-spoked Streem G.48 at 1690€ and the same rim laced with Sapim CX-Ray stainless at 1390€, for roughly 150g. If you're buying wheels to go faster on gravel, the 48mm depth and 45mm outer width matter more than the spoke material — Newmen built the rim profile around 45-50mm tires, so the tire and rim actually sit flush instead of the tire ballooning out and wrecking the airflow. The 27mm hooked internal bead is the other number worth caring about: it holds a 45mm tire near its stated size, which keeps your pressure math honest if you're running low enough to float over washboard. Rated to 130kg system weight and tested to XC MTB standards, so a 95kg rider with bikepacking bags isn't out of bounds.
The multi-size thing is where I'd pump the brakes. Newmen is promising 28", 30.5"/750d, and 32" across both depths, but today you can only buy 28" carbon-spoke G.48s. Steel-spoke versions land spring 2027, and the big diameters have no date at all. If you've got a normal gravel bike and a finite number of Saturday hours, buy the 28" and stop thinking about it — the 32" conversation requires a frame that doesn't exist in most garages yet. Nobody's reselling a 30.5" wheelset in three years either. The shallower G.48 is the smarter pick over the 62mm if your rides include real climbing or crosswinds on exposed ridgelines, which is most of us.
