Park Tool TLR-1 is great for any threaded assembly found on a bicycle, including threaded bottom bracket cups, disc brake rotor bolts, stem bolts, and more. Adds security and longevity to any threaded application while still allowing for future removal. TLR-1 is oil tolerant and compatible with steel and aluminum threads. 10 mL (0.34 fl. oz.) bottle Not recommended for titanium threads NOTICE: When retaining compound or threadlocker is used on carbon fiber surfaces, adhesive primer must first be applied. Failure to do so could result in permanently bonded parts. CAUTION: Some painted surfaces can be sensitive to threadlockers, retaining compounds and primers. Test first on an inconspicuous area to see if it causes a stain or discoloration. Clean off any excess from painted surfaces immediately.
