Shimano Quick Drag Washers.
Available in sets of 3 (3 washers per spool).
This listing is for 3 spools (9 washers) - see my other listings for washers to suit 1 or 2 spools.
These are not shabby hand cut washers, they are made using high precision production press tooling from PTFE/Teflon.
They will fit -
Ultegra 5500 XTB / XSB (see my other listing for Ci4 version)
Ultegra 5500 XTC / XSC (see my other listing for Ci4 version)
Ultegra 5500 XTD / XSD
Ultegra 4500/5500 Ci4 XSA
Used without any grease - Teflon/PTFE has a much lower coefficient of friction than carbon. Nothing sticks to it, thats why its used on frying pans...
Heat resistant up to 250+ Deg Celcius - no need for more unless you're fighting 50MPH marlin with a drag set at 30lb.
No initial 'Stiction' meaning the drag starts to work without any jerking or 'lumpiness', very smooth.
Very cheap.
