Super boosted.

When the trail ahead looms in formidable proportions, you'll be happy to have the Ibis 738 27.5in Boost Wheelset under your ride. Its massive 34mm internal rim width and burly 38mm external width lays down a giant, stable footprint for confident grip in loose situations. The 738 allows super-low tire pressure in the range of 10-18 PSI with 2.8-inch tires, which means more traction and less jarring from rock gardens and other lumpy trail imperfections. If you're more of the rounded profile 2.24-2.5-inch tire type, these rims also let you drop the pressure to somewhere in the realm of 18-25 PSI for low-pressure advantages. As an added bonus, Boost hub widths equate to unrelenting stiffness, which in turn makes for increases precision and responsiveness through rough, technical trails.

The 738 boasts aluminum construction for a price-conscious wheelset with proven durability demanded by aggressive trail riders. Tipping the scales at a respective 1880 grams, it's certainly competitive for such a wide wheelset designed for plus-sized tires. Each wheel is laced with 32 Pilar spokes for dependable strength. They're available with a HG driver for Shimano/SRAM 9/10-speed drivetrains or a XD driver for SRAM's exceptional 11 or 12-speed one-by drivetrains.

  • Stout wheelset for shredding trails on plus-sized tires
  • Lightweight and durable aluminum construction stands up to trail abuse
  • 34mm internal width pairs well with 2.8-inch tires
  • Stealthy appeal without flashy logos or loud colors
