SmoothDrag CarbonTex Drag Washer Kit – Calcutta 50 & 50B Series
Restore and refine the performance of your ultra-light round reels with the SmoothDrag CarbonTex Drag Kit, specifically precision-cut for the Shimano Calcutta 50 and 50B series. These compact reels are the "jewels" of many collections, favored for their incredible palming comfort and precision when finesse fishing for trout, bass, or light saltwater species.
Upgrading to CarbonTex washers is a critical improvement for these small-frame reels. Because they are often used with light fluorocarbon or monofilament lines, eliminating start-up inertia—that split-second "stick" before the spool turns—is the best way to prevent snapped lines and pulled hooks on the initial strike.
Key Performance Benefits
-
Finesse-Grade Smoothness: Virtually eliminates "drag jerk," ensuring a fluid line release even at the very light settings required for thin-diameter lines.
-
Modern Material Upgrade: Replaces the original factory felt or composite washers with heavy-duty carbon fiber that won't compress or "flat-spot" over time.
-
All-Weather Reliability: CarbonTex does not absorb moisture, swell, or rot, ensuring your drag feels the same in a morning mist as it does in the midday sun.
-
Direct Fitment: Sized specifically for the smaller internal gear diameter of the 50-sized Calcutta chassis.

Professional Maintenance & Lubrication
To achieve the legendary "silky" feel of a CarbonTex system and protect the precision brass gears of your Calcutta 50, proper lubrication is essential during installation:
-
Drag Surface Treatment: Apply an extremely thin, almost translucent coating of Deuthlon Reel Grease to both sides of each CarbonTex washer. This specialized grease is formulated to withstand pressure while providing a waterproof barrier that prevents "chatter."
-
Mechanical Fluidity: Use Deuthlon Reel Oil on the spool bearings and the level-wind worm gear. On these small reels, high-quality oil is the secret to maintaining the effortless casting distance they are known for.
Small Reel Tip: When servicing the Calcutta 50 series, check the small tension washers (Belleville washers) under the star drag. Ensure they are clean and stacked in the correct "opposing" orientation ( ) to provide the proper spring tension against your new carbon washers.
