Bottom Bracket Installation Tools
This tool has been designed & manufactured in the UK. The handles are made of a durable CNC machined alloy press which has been anodised for extra durability with Stainless Steel handles. The M12 rod is 195mm long & made from stainless steel. We have tried & tested this tool in a workshop environment to ensure professional quality durability & complete corrosion resistance wherever the tool is stored.
The Drifts (Presses) are manufactured from a CNC Alloy & Anodised for durability & corrosion resistance.
The Drifts that press onto the outer races of a bearing have been designed to be fractionally smaller outside diameter so that they do not become stuck in a Bottom Bracket Shell
The Specifications are as follows:-
If you look after your bearings regularly you shouldn't need to replace your other washers & hardware. Keep everything well greased, avoid pressure washing at all cost & avoid using solvent based sprays & lubricants around your pivots as these dissolve the grease in the bearings
If you're not sure about compatibilty please ask.

Our Bearings Range!!
Chrome Steel (ABEC 1):- Great value for money sealed cartridge bearing. Hardened Chromium Steel balls in a steel cage with a generous grease fill.
Looked after with regular greasing & avoid pressure washers & solvent cleaners they will last well in normal off road riding conditions.
Stainless Steel (ABEC 1):- Great resistance to corrosion in harsh wet riding conditions. Grade 440C Stainless Steel balls in Stainless Steel cage & races.
Grade 440C stainless steels are high carbon steels, which attain the
highest hardness, wear resistance and strength of all stainless steel
grades after heat treatment. These properties make this grade suitable
for applications such as valve components and ball bearings.
Very hard wearing with a high grease fill.
The Hybrid Ceramic BB30 Bearings
Bearing size: 30mm(ID) x 42mm(OD) x 7mm(W)
Balls: ZrO2 Zirconium Oxide ceramic balls
Type: Deep groove ball bearing
Cage: Nylon low friction high speed balls retainer
Closures: 2 x rubber sealed-races
Races: Stainless Steel - High Corrosion Resistance
Zirconium Oxide & Silicone Nitride ceramic ball bearings are superior to common steel ball bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM’s, reduce overall weight.
Because ceramic ball is a glass like surface it has an extremely low coefficient of friction, high rigidity, corrosion resistance and is ideal for applications seeking to reduce friction. Ceramic balls require less lubricant and have a greater hardness than steel balls which will contribute to increased bearing life. Thermal properties are better than steel balls resulting in less heat generation at high speedsAlternatively we can professionally fit these in your frame for you if you're local to SK13 (Glossop), please enquire.
We strongly recommend that you have these bearings professionally fitted into your frame with the correct tools.
