Pressfit Pro PRTLB061 road bike and mountain bike bottom bracket installation tools

The Pressfit PRO PRTLB061 bottom bracket installation tool is a press designed to install Pressfit bottom brackets cleanly and precisely on road bikes and mountain bikes. Compatible with bottom brackets using 24 mm and 30 mm axles, this tool applies even pressure to the cups to ensure a neat fit, without exerting any inappropriate force directly on the bearings or the frame.

Made from sturdy steel and fitted with an ergonomic handle, the PRO PRTLB061 is equally suited to maintaining a bike at home as it is to regular use in a workshop. It is a particularly useful piece of equipment for cyclists and mechanics who wish to fit a Pressfit bottom bracket with greater precision and safety than with makeshift tools.

A press designed for Pressfit bottom brackets

Unlike threaded bottom brackets, Pressfit systems are fitted directly into the frame by pressing. The quality of the fit is therefore essential: the cups must be positioned correctly and remain perfectly aligned during insertion.

The PRO PRTLB061 is designed specifically for this task. It allows both cups to be positioned on either side of the bottom bracket shell, then gradually brought together using the clamping system. This method enables you to control the insertion process and minimise the risk of the cups being fitted crookedly.

PRO states that it is compatible with bottom brackets using 24 mm and 30 mm axles, which covers, in particular, common configurations associated with the following standards Shimano, Hollowtech II and BB30.

A Pressfit tool for road bikes and mountain bikes

The PRTLB061 is suitable for a wide range of applications on road bikes and mountain bikes fitted with a compatible Pressfit bottom bracket.

In particular, it can be used to fit bottom brackets from various brands, provided the exact bottom bracket standard and the required dimensions are checked. Specialist retailers note compatibility with the following Pressfit bottom brackets Shimano, SRAM, FSA and Campagnolo.

Please note, however, that ‘Pressfit’ does not refer to a single standard. Before carrying out any work, it is therefore essential to identify the standard of the frame and bottom bracket to ensure that the tool and cups used are suitable.

Steel construction and ergonomic handle

The PRO PRTLB061 features a steel construction, designed to withstand the forces required to fit a Pressfit bottom bracket. It weighs approximately 400 g, according to information available from specialist retailers.

Its ergonomic handle makes it easy to grip and allows for gradual control of the pressure applied during assembly. This design makes the tool suitable for both professional workshops and cyclists who carry out their own bike maintenance.

For a carbon frame, we recommend taking particular care: the contact surfaces must be clean, the cups correctly positioned and the pressure applied gradually. The manufacturers’ assembly instructions particularly emphasise maintaining a parallel contact surface during pressing.

How do you use the PRO PRTLB061 press?

The operating principle is relatively simple:

1. Check the Pressfit bottom bracket standard and ensure compatibility with the tool.
2. Carefully clean the housing recess in the frame.
3. Position both jaws correctly.
4. Install the press so that it is perfectly aligned.
5. Gradually tighten the tool to press the cups into the frame.
6. Check regularly that the cups remain parallel to the housing.
7. Stop tightening once the cups are correctly in place.

The key point is never to force a housing that does not fit normally. Unusual resistance may indicate a problem with compatibility, positioning or tolerances.
