Loctite on Spokes: Summary
I've been searching through the group about whether or not to use
Loctite on spokes. Here's a summary of opinions and notes: 1) The biggest risk is longitudinal torque tensioning of the spoke wire, (a particular problem with bladed spokes); 2) It's not necessary for a properly tuned wheel; 3) Loctite Threadlocker Red (271) requires a brazing torch on the nippled to loosen it from the spoke, possibly damaging the rim -- don't use it; 4) Loctite Threadlocker Blue (242) is okay; 5) Loctite Threadlocker Purple (222) is best and can even be applied after threading the spoke onto the nipple. My personal experience with the liquid 242 (not the stick) is that it requires excessive spoke torsion (1/2 turn on 14G spoke) to break it after it sets, and it requires considerable torque even after it's broken. -- Daniel |

Interesting! ) I have somewhere Loctite 242 and 222, might testi it myself ) |

The home mechanic may find it difficult or impossible to put enough tension on the spokes of a low spoke count wheel. Other assertions that you made may be true also. -- Michael Press |

Loctite on Spokes: Summary
3) Loctite Threadlocker Red (271) requires a brazing torch on the
nippled to loosen it from the spoke, possibly damaging the rim -- don't use it; Are you correct here from experience? Surface area and lock's advertised break and yield values are inversely proportional and not arithimetic. Example-blue on pulley wheel bolts is less effective than regular red. Reg red does not require heat he the surface area is lower than the heat spec One problem, obvious in nature, not in conjecture-what lubes the nipple/spoke during adjustment? Lock? Recommend an additive for slow cures? Lock works only on steel-so if the rim is ferruless-ura PITW I did lock once on a boxless Belgian 27" butbutbut used a bicycle red loctite from palm beach cyclery. The bike red had an retardant fixture time additive, the compound worked well, recommend it highly, and understand its unavailable. Rim under load beyond its design, ran well for a great distance until before the wind (that wind), I ran it into a designer pothole. Linseed is an appropriate substitoot, corrosion proofs ferrules, is appropriately insesitive to sloppiness, and useful for coating tools and steel bike frame scratchs-eg dropouts |

"Best" of a lot that's best *avoided* altogether, more like. My personal experience with the liquid 242 (not the stick) is that it requires excessive spoke torsion (1/2 turn on 14G spoke) to break it after it sets, and it requires considerable torque even after it's broken. Your experience is not unusual. As has been pointed out by experienced wheelbuilders repeatedly, Loctite (of any variety) has, in truth, no valid purpose on the spokes of a bicycle wheel. -- Typoes are a feature, not a bug.
