Is 32-Inches the Ultimate Gravel Wheel Size? Meet the Stinner Refugio 32

Is 32-Inches the Ultimate Gravel Wheel Size? Meet the Stinner Refugio 32

Santa Barbara-based Stinner Frameworks is embracing the 32”. Known for their meticulously crafted handmade frames, Stinner has just announced the Refugio 32, a bike designed specifically around the emerging 32-inch wheel platform.

Seeing brands like BTCHN’ and Stinner not just embrace the 32”, but innovate with this new wheel size is beautiful. For the first time in a long time, trends and the future are being shaped by small builders and makers who can explore this new tech in ways that make sense for the individual applications. I understand that 32” isn’t for everyone, but as a taller rider, 32” makes a lot of sense, and if smaller riders get bikes specc’ed with 650B/27.5 wheels, why isn’t there a wheel size for the other end of the spectrum? Well, it looks like that question is being answered.

Frame Highlights:

  • Material: Straight-gauge Titanium.
  • Compatibility: Wireless 1x drivetrains only (55mm chainline).
  • Clearance: Massive 32″ x 2.4″ tire clearance.
  • Details: T47 bottom bracket, internal brake routing through the downtube, and three bottle cage mounts.
  • Dropouts: Stinner UDH 160mm flat mount CNC Ti dropouts.

The philosophy here is simple: “Smooth is Fast, Fast is Fast”. By utilizing larger wheels, Stinner aims to create a ride where trail chatter and roots effectively fade into the background. The Refugio 32 is designed from the ground up to optimize this platform, promising a bike that carries momentum over rough terrain while remaining “calm and precise” in its handling.

While Stinner offers standard sizing from Medium to XXL, they also offer custom geometry for riders who want to further dial in their fit on this unique platform.

The heart of the Refugio 32 is a straight-gauge titanium tubeset that is welded in-house in Santa Barbara. It features a classic bead-blasted raw Ti finish (chef’s kiss), accented with your choice of polished titanium or black decals.

Up front, the Refugio 32 is paired with a full-carbon fork from their in-house component brand, Stoic Components. It’s built for the long haul, featuring triple mounts on each leg with a 6lb load capacity, fender mounts, and internal routing for a dynamo wire. Like the frame, it clears a 32″ x 2.4″ tire and uses a 110x15mm spacing.

To support the 32-inch format, Stinner has spec’d the bike with Stoic carbon rims (32mm internal width) laced to DT Swiss 350 hubs. These wheels are wrapped in Maxxis Aspen 32″ x 2.4″ tires, a fast-rolling choice that should complement the bike’s momentum-focused design.

Availability and Details

The complete build leaves little to be desired, featuring a SRAM GX T-Type Transmission AXS groupset and Rival AXS E1 levers. The cockpit is rounded out with a Stoic gravel handlebar and Teravail components.
