The Burgtec 104mm BCD Thick Thin Chainring is built to keep your chain locked on through the roughest terrain. Designed as the perfect partner for Shimano cranks, this Outside Fit chainring works in concert with a clutch derailleur to deliver reliable chain retention without a guide. Finished in Burgtec's Steel colourway and rated for e-bike use, it handles the higher torque demands of motor-assisted riding without complaint. Available in 30T, 32T, 34T and 36T to suit a wide range of trail and e-bike setups.

Design Features

  • Thick-thin tooth profile alternates tooth width to mesh precisely with chain rollers, dramatically improving chain retention and eliminating drops without a dedicated guide
  • Outside Fit design positions the ring correctly on Shimano 4-bolt 104mm BCD cranks for proper chainline and clearance
  • E-bike rated construction handles the elevated torque output of mid-drive motors, resisting wear and deformation where standard rings can fall short
  • Aerospace grade aluminium keeps weight in check while delivering the stiffness needed for consistent power transfer under load
  • Optimised for use with clutch-style rear derailleurs — the combination of thick-thin profile and clutch tension provides maximum chain security on technical trails
  • Available in 30T, 32T, 34T and 36T to match your terrain and motor output; note that the 30T variant features threaded bolt holes requiring 8mm x 0.75mm x 8mm long chainring bolts
