BTCHN’ Bikes in California is the latest maker to offer its take on the 32-inch mountain bike. The new BTCHN’ Alpina was designed around the idea that composure creates speed, and it features a 120mm travel fork, 32″ wheels, and a super boost rear hub. Check it out here…

In case you missed it, we published our Gear Index of 32-Inch Tires today to get ahead of the upcoming surge in demand. If there’s one thing that helps drive the need for tires, it’s more 32-inch bikes, and BTCHN’ Bikes in California is the latest to step up to the plate with new Alpina. As BTCHN’ Bikes’ puts it, “The Alpina is not a scaled-up 29er but a platform intentionally designed to maximize the unique attributes of a new wheel size.” It’s a California-made steel hardtail designed around a 120mm travel fork and 32″ wheels, and the bikes are built in batches in partnership with Falconer Cycles.

The Alpina is designed to take full advantage of the 32″ wheel size, offering “increased rollover efficiency and a robust contact patch for maximum traction and cornering grip,” as BTCHN’ puts it. It has a low bottom bracket to make up for massive wheels and a ride quality that BTCHN’ describes as stable and planted.

The Alpina is available in three sizes with a single high-end build kit that prioritizes domestic manufacturing. You’ll find parts from White Industries, Astral, and Madrone paired with SRAM Eagle AXS shifting. The Alpina comes stock with Maxxis Aspen 32 x 2.4″ tires, with frame clearance for up to 32 x 2.6″ tires—if they ever exist. The stock build includes a Wren Inverted 32” Fork, but you can upgrade to an Intend BC Inverted fork, a PNW Dropper Post. It uses a super boost 12 x 157mm rear hub to increase the wheel’s strength.
