Win a Custom Dream Bike While Building Sierra Trails
The Sierra Buttes Trail Stewardship (SBTS) is back with their Builders for Builders 2025 fundraiser, and this year's prize is absolutely ridiculous. We're talking a fully custom bike built by your choice of frame legends: Significant Other Bikes, Retrotec, Sycip, Prandus, Stinner Frameworks or Mosaic.
Born in the uncompromising terrain of Colorado, Mosaic prioritizes for maximal performance on every surface. Merging meticulous welds with modern geometry and componentry, each frame is a mix of precision engineering and industrial artistry. Mosaic builds metal bikes for fun, adventure, racing and building character through suffering. Each frame is a showcase of timeless style and contemporary functionality. Mosaic strives to bring our level of craftsmanship to more and more riders, we are for growth with zero compromise. They are a team of grubby makers making bikes that are hand-crafted to be used and abused, not merely coveted.
Here's the deal: Drop just $10 between now and September 30, 2025, and you're in the running for what could be the bike of a lifetime. The winner picks their dream builder, gets a custom paint job, and the whole thing gets spec'd with high-end components from Paul Components, White Industries, and WTB!
But here's what makes this even better than your average bike giveaway – every dollar goes directly to expanding trail networks in California's Lost Sierra. SBTS is pushing south toward Truckee, east to Reno, and pioneering Fire Hardened Trail techniques for wildfire mitigation. Plus, they're less than a mile away from completing the 13-mile Beckwourth Peak Trail loop starting from Portola City Park (yep, home of Lost and Found Gravel Festival).
Since its inception, Builders for Builders has raised over $100k for trail building – the kind of unrestricted funding that actually gets dirt moved without bureaucratic nightmares. This is a one-off custom build, so expect some wait time depending on your chosen builder's queue. But honestly, good things are worth waiting for.
A $10 donation could score you a handcrafted masterpiece from legendary builders.
