• The Shimano SM-BH59-JK-SS brake hose is an original equipment hydraulic hose designed for Shimano disc brake systems that use an SM-BH59 hose and straight fittings. Available in lengths of 1000 mm or 1700 mm, it can be used to replace a worn, damaged or too-short hose on a road bike, mountain bike, touring bike or certain city bikes fitted with hydraulic disc brakes Shimano.

  Thanks to its straight fittings at both ends, this hose ensures easy installation when the lever and caliper configuration complies with this standard. It can also be cut to the required length, allowing for a neat routing that fits the frame.

  Shimano SM-BH59-JK-SS hydraulic hose

  The SM-BH59-JK-SS is designed for Shimano hydraulic braking systems operating withmineral oil Shimano. It uses the SM-BH59 hose standard and straight-to-straight connections, without banjo fittings.

  This design makes it a versatile solution for replacing an original Shimano hose on many disc brake systems. Shimano specifically recommends its use with SERVO WAVE levers and compatible ONE WAY BLEEDING calipers.

  The hose is available in two lengths:

  • 1000 mm: generally suitable for a front brake or for set-ups requiring a relatively short length.
  • 1700 mm: generally preferred for a rear brake, particularly on mountain bikes and frames with a longer routing path.

  The length can be adjusted by cutting the hose, provided the correct procedure and connecting components are used.

  Straight connections for direct fitting

  The suffix JK-SS indicates a straight-connect configuration. The SM-BH59-JK-SS is therefore suitable for installations where the hose connects directly to the lever and caliper via straight connections.

  Before ordering, it is important to check the type of fitting used by your brake Shimano. A hose with the correct diameter or length is not necessarily compatible with all calipers and levers Shimano.

  In particular, the SM-BH59-JK-SS must not be confused with hoses Shimano that use other standards or different types of fittings.

  A hose suitable for original equipment replacement

  The SM-BH59-JK-SS is particularly useful for maintenance or repair work. A hydraulic hose can be replaced following damage, a cut, a leak, or simply as part of a complete overhaul of the braking system.

  The kit includes the components required to connect the hose, notably inserts and ferrules. The available specifications also indicate that connection nuts are included in the kit.

  Depending on the version and fitting procedure, certain tools or accessories Shimano may be required to cut and connect the hose correctly.

  Brake compatibility Shimano

  The SM-BH59-JK-SS is used on various hydraulic braking systems Shimano. Components listed as compatible include, in particular, certain levers and calipers Shimano 105, RS, Metrea, Acera, Deore, Altus and other components Shimano that use the SM-BH59 standard and the corresponding straight fitting.

  It can be found, for example, on systems such as:

  • Shimano ST-RS685 / BR-RS785
  • Shimano ST-RS505 / BR-RS505
  • Shimano ST/BR-RS405
  • Shimano BL-U5010 / BR-U5000
  • Shimano BL-MT500 / BR-MT500
  • Certain systems Shimano , Deore, Acera and other MTB ranges

  However, exact compatibility depends on the model of the lever and caliper, as well as the type of connector. It is therefore recommended that you check the part numbers of your components before fitting.

Fitting the Shimano SM-BH59-JK-SS hose

When replacing a hydraulic hose, you must follow the Shimano procedure applicable to the braking system in use.

If the hose is too long, it can be cut to the correct length. The cut must be clean and made using the appropriate tools to ensure the connector fits properly and the joint is leak-proof.

After connection, the hydraulic circuit must be checked and, if necessary, bled using mineral oil Shimano.

When carrying out work on a braking system, if you are not familiar with hydraulic bleeding, it is best to have the work carried out by a bicycle mechanic.

In summary

Shimano SM-BH59-JK-SS is a black hydraulic disc brake hose with straight fittings, designed for Shimano systems compatible with the SM-BH59 standard. Available in lengths of 1000 or 1700 mm, it can be cut to fit the bike’s routing exactly.

It is a reliable solution for replacing a worn or damaged Shimano hose, on certain road bikes as well as on many mountain bikes and touring bikes fitted with compatible Shimano hydraulic brakes.
