Bearing Press Kit for Sonder Bikes

Regular price £41.00

Bearing press tool kit for Sonder MTB Frame Pivots - Cortex, Evol, etc

Each kit is tailor made with all of the tool sizes required to install the rear suspension pivot bearings on the selected Sonder frame (one, two, three or more tool sizes depending on the frame)

Designed to install the sealed cartridge bearings that are found on many brands of bicycle hub and full suspension MTB bike frames. Each tool consists of a pair of drifts (sometimes called spacers or bushings) machined to match the bearing's inside and outside diameters, and a threaded rod to pull the drifts together.

  • Designed in the UK
  • Most sizes available, small and large
  • Bearings are installed straight, kind to frame

Each can be purchased with either T-bar handles or simple nuts. Both of these options include the selected pair of drifts and a threaded rod. The T-bar handles make the tool super-easy to use, while the nuts are a functional and cheaper option and are used with normal spanners.


All of our presses are designed around an 8mm threaded rod, but if you already have a press from another manufacturer that uses a different diameter, we can bore out our drifts to match at no additional cost.  Just drop us an email.


The tool is shaped to press the outer race of the bearing, meaning that no stress is placed across the bearings, prolonging bearing life and protecting the frame or hub.

Unlike some other bearing press designs, this design closely fits the inside diameter of the bearing to ensure that the tool remains accurately centred and the bearings are pressed in straight.


How To Use

The press tool is simple to use.

Here's a quick demo:

  • Two drifts are supplied which accurately match the size of the bearing. The shape of the drifts ensures that it accurately centres on the bearing, and that pressure is applied to the outer race.
  • Tightening the nuts or handles draws the spacers together, pressing the bearing into place. For best results install one bearing at a time.



See our Manuals page to download the more detailed instruction sheets which come withour press orders, now available in several languages.

Note that each tool is specific to one bearing size. It is designed to match the internal and external diameters and can't be used on bearings with different sizes.

We offer several options to customise your press to suit your specific needs, including:

  • Extensions to allow the handles to stand clear of any obstructions or to allow you to press a bearing deep into a recess
  • Thrust bearings to make the tightening of the press super smooth! 





Shipping & Taxes

We aim to dispatch all orders within 1 working day

Orders within the UK will be shipped by Royal Mail RM24 (First Class)

International orders are welcomed and will be shipped by Royal Mail International Standard (Airmail). Please refer to our Shipping & Taxes page for more info.

Our tools can be selected either by the bearing size or by the bearing's standard reference code.

Standard references take the form of a three or four digit number, such as 688, or 6902 for example. These codes are often moulded onto the bearing's seal. You might see something like 6902-2RS on the seal. The first digits are the standard reference.  The second part (2RS in this case) refers to the seal type and doesn't matter for tool selection.

Alternatively, tools can be selected by their inside (ID) and outside (OD) diameters and width.

Note that each tool is specific to one bearing size and can’t be used on bearings with different dimensions.
