Spoke Threadlocker

Several excelent options exist for threadlockers on spokes.

Threadlocker Etiquette

• Loctite threadlockers should never come in contact with plastics of any kind. The threadlocker will feed on the plastic and destroy it.
• Other than very special products, a threadlocker is designed to bond to clean, oil free surfaces. Oil will reduce or eliminate the strength of the bond.
• Activators may be used in certian cercumstances, but they reduce the strength of the threadlocker.

Pre-build Option

One of the best options available for threadlocking spokes is Loctite 242 or it's slightly stronger (especially with brass) relative Loctite 243. Both are commonly refered to as 'Blue Loctite'. I have personally used this for over 10 years. It is great.

If you have concerns about the threadlocking strength of 242, Loctite 222MS can be used instead. It is less powerful but less comonly available.

Post Build Option

If it is difficult or a wheel build must be done without 242 or 222MS at hand, Loctite 290 may be used after the build is done. This is not prefered, but acceptable in special cases.

Never an Option

Under no circumstances should Loctite 271 or any of the higher strength threadlockers ever be used on spokes. These are commonly refered to as 'Red Loctite'.

Other Considerations

• Grease or oil on the shoulder of the nipple or eyelet will make the build go much smoother, especially if using aluminum nipples.
• If building using a Mavic UST rim, the threaded eyelets should be fastened using Loctite 243 or equivilant as per UST PDS
