The Builders for Builders Fundraiser is an event thrown by Sierra Buttes Trail Stewardship (SBTS), and it’s back for 2025. They’ve teamed up with a select group of custom frame builders, Significant Other Bikes, Retrotec, Sycip, Prandus, Stinner Frameworks, and Mosaic to allow you the opportunity to win your own custom, handcrafted frame.
Every $10 donation that’s made between now and September 30th, 2025, will give the donor a chance to win. The winner will get to pick the frame builder of their choice from the list to build their very own dream frame.
After the winner picks the frame builder, the bike will get a custom paint job and it will be decked out with high-end, blingy bike bits from top component brands like Paul Components, White Industries, and WTB.
Let’s Meet The Builders
Born in the uncompromising terrain of Colorado, Mosaic prioritizes 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.
Sycip Designs has been building bikes in Northern California since 1992. These days, Jeremy Sycip does the fittings, designs. He also fabricates all the frames in a small shop in Santa Rosa, California. All his frames are custom-built and offered in steel, titanium, or aluminum. Steel frames are also offered in Tig, Lugged, or Fillet Brazed construction.
Retrotec and Inglis Cycles is a small, one-man shop building custom and production steel bicycle frames since 1993. Curtis Inglis handcrafts his frames in the world-famous Napa Valley wine-growing region.
Ashley King is the founder of Significant Other Bikes, a small fabrication studio based in Denver, Colorado. After years of building for companies like REEB, Merlin, and Mosaic, she started SigO as a way to explore her own perspective. Both as a builder and a designer. Her work is rooted in curiosity, clarity, and precision. And guided by a soft spot for quiet details that do a lot of heavy lifting. She welds in titanium and steel, asks a lot of questions, and genuinely wants to know what you’re chasing when you ride.
Wait, There’s More!
Stinner Frameworks builds top-tier stock and fully custom steel and titanium bicycle frames. They use some of the lightest and highest-quality tubing in the world. Its Santa Barbara, California, workshop combines craftsmanship with performance-oriented details to produce frames designed to excel in their respective disciplines.
Prandus was maybe founded in a cave deep in the Himalayas in 1918. Or maybe they started making frames for [redacted] bicycle company early in the pandemic in response to long lead times from overseas factories. Whatever you believe. Our deep roots in industrial design and aerospace fabrication help us bring you the bicycle of all time. They invented tracklocross. Norm Macdonald had a Prandus. Custom and also stock geo fancy sport bicycle.
Five Bucks a Foot
If you’re familiar with SBTS’s 5 Bucks a Foot fundraiser, Builders for Builders is using a similar concept. All proceeds support Stewardship efforts to expand trails in the Lost Sierra. To date, the Builders for Builders program has raised over 100k. All of which is allocated directly to trailbuilding and community efforts through the SBTS.
“The funds will specifically support several ongoing projects to expand SBTS’s trailbuilding footprint south toward Truckee and east to Reno. As well as support plans to incorporate building techniques to create Fire Hardened Trails to manage vegetation for wildfire mitigation”.
Money raised will also be contributed to help complete the Beckwourth Peak Trail. The Beckwourth Peak Trail is a 13-mile non-motorized loop that starts from Portola City Park. This is the home of the Lost and Found Gravel Festival.
Together, we can make more Dirt Magic in the Lost Sierra. Go HERE to donate.
