If you're seeking a striking wheelset with reliable strength and stiffness, look no further than the Crank Brothers Iodine 3 27.5in Boost Wheelset. Different by design, the Iodine 3 represents a shift in wheel design that's both useful on the trail and aesthetically pleasing. This particular version is billed as an "elite level" alloy wheelset for enduro and all-mountain riders concerned with reliable stiffness and strength. Tipping the scales at 1760 grams, it's certainly a competitive weight for the rider seeking to shed a few grams from their heavier stock wheels—all without emptying their wallet for pricier carbon offerings on the market. It saves approximately 70 grams from the Iodine 2, mainly from using a lighter alloy for the freehub instead of steel.
The first thing you'll notice on the Iodine 3 is the striking twinspoke design, which catches attention as you demolish rock gardens, send side-hits, and roost around berms with speed. Not only is this design easy on the eyes, but more importantly, the twinspokes increase overall stiffness and strength with their triangular structure. For those unfamiliar with engineering principles, triangles are regularly employed on bridges and overhanging structures, namely for their load-bearing ability. Translated into the Iodine 3s riding characteristics, you'll appreciate a noticeable increase in stiffness over flimsier stock wheels. Another benefit, the spoke's overall mass is placed closer to the wheel center for quick acceleration when you're climbing and bursting from tight corners.
Seeing the 6061-T6 alloy rim sits at 28 millimeters across (internal width), the Iodine 3 is sufficiently stout for riding tires in the range of 2.3 to 2.5 inches on the trail. This 28-millimeter width provides plentiful support without deforming rubber into a bulbous shape and exposing sidewalls to slashes from sharp rocks. The undrilled rim profile makes tubeless set-up a breeze, as you don't need to use rim tape. Another thing to note, Crank Brothers redesigned their hubs a couple of seasons back for greater reliability. Both hubs run on sealed cartridge bearings, with the rear hub having a three-pawl freehub with 21 points of engagement.
Please note, this wheelset comes in Boost spacing and it's only compatible with Shimano and 9/10-speed SRAM drivetrains. If you're rocking newer 11-speed or Eagle 12-speed drivetrains from SRAM, you'll have to purchase a separate XD freehub body through Crank Brothers.
