S&M L.A.M.F. Frame
S&M L.A.M.F. FRAME
Product Overview
The S&M L.A.M.F. Frame is Jason "Timmy" Ball's signature dirt jump and street frame built with 30+ years of real-world riding and wrenching experience behind it. Constructed from heat-treated 4130 chromoly with a dialed geometry focused on stability and control, this frame is designed for riders who session parks, hit dirt jumps, and ride street with an emphasis on durability over weight savings. Available in five top tube lengths to accommodate a wide range of rider sizes.
Key Features
- 14″ rear end with welded chainstay brake mounts – Short backend delivers quick, responsive handling while welded mounts provide clean brake setup and increased chainstay strength in a high-stress area
- 74.5° head tube angle – Steep front end keeps the bike stable at speed and responsive in transitions, ideal for dirt jumps, bowls, and technical street riding
- 11.8″ bottom bracket height – Higher BB clearance prevents pedal strikes on coping, ledges, and uneven terrain while maintaining a balanced feel
- Integrated Campy-style head tube – Accepts integrated headsets for a clean front end with reduced stack height and improved stiffness
- Mid bottom bracket shell – Standard mid BB (19mm ID) works with most modern cranksets and provides solid bearing support
- Heat-treated 4130 chromoly construction – Full chromoly tubing heat-treated post-weld for improved strength and fatigue resistance over the frame's lifespan
- 5.05 lb weight – Built to take a beating without unnecessary bulk; weight reflects S&M's focus on durability and rideable geometry
