Proper support for high volume tires.

The Reserve 37 27.5 Industry Nine Boost Wheelset is the latest addition to Santa Cruz's Reserve line of carbon wheels, offering up a wider 37-millimeter internal width to properly support the higher volume trail and plus-sized tires becoming increasingly popular for their added compliance and monstrous traction over loose rock and rubble. Santa Cruz recommends running tires in the range of 2.5 to 3.0-inches in width, so you'll have optimal tire footprint without deforming a wider tire into an overly bulbous shape like you'd experience by squeezing it on a narrower rim.

This particular wheelset enjoys the unrelenting stiffness and strength you've come to expect from Santa Cruz's Reserve line of carbon wheels. Santa Cruz designed them specifically to be some of the strongest carbon hoops on the market through extensive research of critical failure points, going so far as to completely overhaul the impact testing protocol used on traditional carbon rims. Instead of replicating the pothole-like impact test of traditional carbon wheels, Santa Cruz developed their very own testing procedure that simulates one-sided impacts that normally occur when a rider lands on a square, protruding rock after getting airborne or carrying momentum into a rock garden.

Once they redesigned the testing protocol to better simulate these square-edge hits, Santa Cruz began to find the leading carbon wheels from many manufacturers not only broke along the expected bead, but they also failed along the spoke nipple interface, due to the increase in spoke tension as the wheel flexed upon impact. To mitigate these breakage issues, Santa Cruz beefed up the rim bead, increasing its thickness by one millimeter along each side for improved resiliency when you're thrashing the living hell out of these wheels. The design engineers at Santa Cruz then fortified the spoke holes with square-shaped reinforcements you can visibly see, which protect the spoke nipples from suddenly pulling through due to harsh impact.

It's worth noting this particular Reserve 37 Wheelset is laced to Industry Nine's exceptional Torch Hubs, which feature a nearly instantaneous 3-degree engagement for power up and over trail obstacles standing in your way. Teflon shields and O-rings snap solidly onto the endcaps of the hubs, ensuring trail debris and dust doesn't compromise the wheel's engagement over time. Additionally, you can choose a front wheel that's built with a Torque Cap compatible hub for bolstering added stiffness over the front wheel with compatible RockShox Forks (the Pike and Lyrik are the two most popular with Torque Caps).

  • Familiarity: I've put it through the wringer

Love these things. Insanely lightweight. Surprisingly quick acceleration on these things while staying light. Super durable as well, and with the lifelong guarantee that is offered I don't have to worry too much if I go crazy with these on. Amazing stuff once again.
