The 3x7 drivetrain, built to your bike

A drop-bar triple 7-speed road groupset for classic and restoration builds. The front derailleur is shared across Microshift's 7/8/9-speed road range — chainring cage width, not rear speed count, is what a front derailleur matches. This kit is the drivetrain; add the crank, chainring, bottom bracket and brakes you need and leave out what you already have.

Kit includes

  • SB-R373 shift/brake lever pair, 3x7-speed
  • FD-R353 front derailleur, 50-39-30T, clamp mount
  • RD-R32 long-cage rear derailleur, up to 28T
  • 7-speed cassette, 12-28T
  • Chain, 6/7/8-speed

Editable kit: every part can be deselected if you already have it.

Microshift offers a limited warranty covering defects in materials and workmanship on every component in this kit. For warranty support, return the item to Tune Cycles.
