To celebrate the 121st Tour de France, our marketing team pooled the company’s resources to sponsor the street furniture along each stage of the race. In collaboration with legendary design icons, we’re commemorating this monumental effort the way all great efforts should be — with a t-shirt.

Pre-orders are live for 6 days only and will ship in approximately 3 weeks.

Looking back at some unpublished details from sloshing around with Matt last winter. He was riding his anniversary parallax, with the energy of a toddler just wanting to smash some puddles.

We have a few 55’s in this dark matte phosphate finish. If you have been on the hunt for our steel frame in a 55, this will be it for a while. We are expecting a quiet 2025 due to current events, so no additional frame deliveries scheduled for 2025 at this time.

Our Story

mashsf.com

[email protected] MASH is born from friends, hard riding, and a love of Bay Area streets, roads, and trails. Testing the limits of track machines on hills and in the human congestion. MASH has grown up around a core of young cyclists now ascending as multi-disciplinary athletes. Dirt in the winter, road in race season, and a fixed drive train every day. The gateway now has a front door. We are here to provide an access point, a space to gather up friends, and a support system for all things bike. Keep coming back for more. MASH San Francisco
