GST-279 full-suspension frame
My full-suspension frame design for TBD Bikes: SLS PA12 prototype lugs on carbon tubes, from the Fusion 360 model to the bonding jig and both triangles. , 1 video -
Dirt Jumper V2: 3D printed in aluminum
A rideable dirt-jump frame printed almost entirely in aluminum (metal LPBF), with generative-design junctions and lattice tubes. , 2 videos -
Dirt Jumper V2: machined junctions
The same V2 frame on carbon tubes, with 7075 aluminum junctions machined 5-axis from my CAM. Industry Nine showed it, unfinished, at Crankworx Whistler 2025. , 8 videos -
Bike Pedals
A bike pedal I keep redesigning: resin prints at home, then PA12 bodies printed at De Anza on 1020 steel spindles I turned. The current revision is V4, "The Reboot." , 4 videos -
Dirt Jumper V1: 12 days to Sea Otter 2025
A dirt-jump frame with SLS-printed Nylon 12 lugs bonded to carbon tubes, designed and built in 12 days for Sea Otter Classic 2025. , 3 videos -
Top-load BMX stem designs
Printed prototypes of my top-load BMX stems, the V1 design in CAD, a lattice version exported for printing, and the basic top-load stem from my TBD Bikes parts set. , 2 videos -
MTB stems for TBD Bikes
Two MTB stems I designed in Fusion 360 for TBD Bikes in spring 2025: CAD for both, and printed parts of the trapezoid-body stem. , 2 videos -
Printed MTB/gravel stem: generative design
An MTB/gravel stem shaped by generative design in Fusion 360 and printed in Nylon 12 on an HP 580, with heat-set inserts for the bolts. , 1 video -
Crank arms and a 3-piece crankset
Crank arms I printed, some in resin and some in powder, with different pocket patterns, a printed chainring and guard, and a 3-piece crankset I designed in Fusion 360 for TBD Bikes. -
Frame lug prototypes
Printed lug, junction and tube-section prototypes, mostly for my Dirt Jumper V1, Dirt Jumper V2 and GST-279 frames.
