Entry-level hydraulic drop-bar CUES, nine LINKGLIDE gears

The CUES U4030 1x9 drop-bar groupset is the affordable way to a hydraulic-disc drop-bar bike: ST-U4030 DUAL CONTROL LEVERS matched to BR-U6030 flat-mount calipers, the RD-U3020 rear derailleur and an 11-36T LINKGLIDE cassette. Add the square-taper FC-U4000-1 crank or the drop-bar FC-U6030-1 if your bike needs one.

Kit includes

  • ST-U4030-R right shift/brake lever, 9-speed, hydraulic (hose kit included)
  • BL-U4030-L left brake lever, hydraulic (hose kit included)
  • BR-U6030 flat-mount hydraulic calipers, front and rear
  • RD-U3020 rear derailleur, SGS cage
  • CS-LG400-9 LINKGLIDE cassette 11-36T (the ratio RD-U3020 is designed for)
  • CN-LG500 LINKGLIDE chain

Options

  • FC-U4000-1 crankset (30 to 42T, 170 or 175 mm) or FC-U6030-1 crankset (40T/170 mm or 42T/172.5 mm)
  • BB-UN300 square-taper bottom bracket for the FC-U4000, or BB-MT501 for the FC-U6030
  • RT-CL700 Center Lock rotors (choose size)

The crank, bottom bracket and rotors are optional extras that start at 0, so e-bikes and bikes keeping their own parts are not charged for them. Every other part can be deselected if you already have it. Levers come with their hydraulic hoses and need a mineral-oil bleed after fitting; Tune Cycles can do that for you. Levers fit 23.8 to 24.2 mm drop bars.

Tune Cycles supplies and fits Shimano CUES across Sydney. Choose your options above; if you are unsure what your frame takes, ask us before you order.

Every part in this kit is covered by Shimano's standard manufacturer warranty against defects in materials and workmanship. Wear from normal use, incorrect installation or crash damage is not covered. For any warranty claim or support, return the part to Tune Cycles and we will handle it with Shimano.
