Engineering Services

We’re lucky enough to have a second engineering workshop on hand, with the capability of milling, turning and 3D printing. To date, our large machines are a Marlow 2A mill and a Colchester Master lathe. This gives us the ability to make and modify parts on a fairly regular basis. The most common job we’re asked to do is to modify 11 speed road cassettes to fit on a 10 speed freehub body.

We can remove broken bolts, stripped/spinning rivnuts can be replaced, we can bond and rivet on front mech braze on mounts, manufacture end caps for hubs.

Some of the engineering services we can offer include:

  • Stripped thread repair
  • Broken bolt extraction
  • Seized seatpost removal
  • Loose rivnut removal and replacement
  • Cassette machining (to fit your 11 speed cassette onto a 10 speed wheel)
  • Brazing
  • Custom tool manufacture (bearing pullers/presses etc.)
  • General spacer manufacture (chainline spacers, hub spacers etc.)
  • General turning and milling
  • 3D printing
  • CAD services
