The G fits the clamps of the older versions of the C clamps. These were the clamps of the early generation of the PCS The clamp is made of welded stamped steel.

There are no studs or clips. These fit the very early generation clamp jaws that were dipped in plastic. The original covers must be cut off before the are slipped over the jaws. Neither jaw side has a recess for cable housing. The fits the clamp jaws on the X and X extreme range clamps. Trade Resources. Fixed cover having no recess B jaw covers installed on clamp. Back To Top. Do not confuse an assembly compound with grease! It is not lubrication — in fact, it provides extra friction wherever it is applied.

Although not recommended for press-fit or threaded applications, assembly compound is very useful on clamping applications , especially involving carbon fiber. A common application is on carbon fiber seat tubes that have difficulty holding the seat post secure. It can also be useful on the interface between handlebars and stems. The grit in this compound will not structurally harm carbon fiber or metal, but you should expect some surface marring. Servicing bicycle components such as the chain, will require cleaners and solvents.

Never use highly flammable liquids such as gasoline, kerosene, or diesel as cleaning solvent. Always use purpose-made degreasing solvent such as Park Tool CB It is possible to reuse cleaning solvents.

Save used solvent in a sealed container and allow it to settle for a few days. The dirt and grit will settle to the bottom. Carefully pour off the solvent and reuse. Scrape the grit from the bottom and dispose of it and spent solvent by contacting your local hazardous waste disposal site, which is typically with a state or county agency. For cleaning the frame use mild cleaners such as a window cleaner, or simply soap and water.

Isopropyl rubbing alcohol is usually adequate for cleaning rim braking surfaces. It is important that cleaners for braking surfaces not leave an oily film. Cutting fluid such as Park Tool CF-2 should be used during any kind of cutting, tapping, facing, or reaming process. It will extend the life of the cutting tool and ensure optimum performance.

When cutting carbon fiber, regularly spray the area with a foaming household cleaner or soapy water throughout the process. This will prevent particles of carbon fiber from going airborne and into your lungs. Bike Washing and Cleaning View Article. New Bike Assembly View Article. Trade Resources. Bearing Systems Loose headset bearings require an application of grease One important application for grease is bearing systems, such as those found on hubs, headsets, pedals and bottom brackets.

Threads Grease is one thread prep option when installing a freewheel Grease is generally an acceptable surface prep option with some caveats for threads as found on mounting bolts, bottom brackets, pedals, axle nuts, etc. Press Fit Press fit bottom brackets should have some kind of surface prep Grease is also a good option for some press fit applications, again with some exceptions.

Insertion When inserting one tube into another, such as when installing a seat post or a quill stem, it is a good idea to apply grease. Clamping Grease should not be used between the stem and the handlebars, or between the steering column and the stem on threadless systems.

Anti-seize compound is not appropriate for bearing applications. Primer It is recommended to use a primer such as Park Tool AP-1 on all component and fastener surfaces prior to application of threadlockers and retaining compounds, especially on carbon fiber surfaces.

Cutting Fluid Cutting fluid such as Park Tool CF-2 should be used during any kind of cutting, tapping, facing, or reaming process. Works on any bike with an inner tube.
