Shimano Tourney RD-TY200 Rear Derailleur 6/7 Speed Long Cage

The Shimano Tourney RD-TY200 rear derailleur represents the evolution of entry-level shifting for 6 and 7-speed drivetrains, combining Japanese brand reliability with competitive pricing. Designed for urban cyclists, occasional touring riders and recreational mountain bike enthusiasts, this component ensures consistent performance in all riding conditions.

Construction technology and materials:

The RD-TY200 structure uses an optimized parallelogram design with 2mm thick tempered steel side plates to withstand impacts and torsion. The main body in glass fiber reinforced composite resin reduces weight to just 350 grams while maintaining structural rigidity. The 11-tooth pulleys with self-lubricating brass bushings ensure smooth rotation for over 10,000 km without maintenance.

Capacity and extended compatibility:

The long cage allows use with 14-28 tooth cassettes while maintaining optimal chain tension. Total capacity 43 teeth: handles differences up to 20 teeth between largest and smallest chainring, 28 teeth maximum on largest sprocket. Compatible with narrow 6/7/8 speed chains 1/2"x3/32" pitch. Works perfectly with Shimano Tourney TX30/TX50 shifters, Revoshift RS35, trigger shifter ST-EF41/51, plus compatible Sunrace and Microshift systems.

Shifting system and geometry:

The parallelogram angle is calibrated to perfectly follow the conical profile of 6/7 speed cassettes. The double spiral return spring ensures rapid shifts to smaller sprockets even with partially worn cables. The 1:1.7 leverage ratio requires less effort at the shifter compared to previous models. Upper/lower limit screws allow micrometric adjustment of derailleur travel.

Professional installation:

Mounting on standard dropouts with included M10x1 nut or direct mount on dedicated hangers. Optimal alignment with upper pulley 5-6mm from largest sprocket. Compatible chainline 43.5-47.5mm. For frames with internal cable routing, reverse spring version (GS) available. Recommended torque 8-10 Nm on dropout, 3-4 Nm on cable bolt.

Real-world performance:

Road tests demonstrate precise shifting up to 90 RPM cadence under moderate 200W load. The reinforced cage prevents deformation with dirty or stretched chains. Anti-corrosion treatment on bolts and pins ensures operation in marine or salt environments. Operating temperatures -10°C/+50°C without performance degradation. Mud and dust resistance certified for cross-country mountain bike use.

Scheduled maintenance:

Every 500 km: external cleaning with specific detergent, cable tension check. Every 2000 km: pulley removal, bearing cleaning, lubrication with lithium grease. Every 5000 km: pulley wear check (replace if teeth worn over 0.5mm), parallelogram play inspection. Estimated service life 15,000-20,000 km with regular maintenance. Replacement pulley kit Shimano code Y5X998040.

Specific recommended applications:

Urban bicycles for commuters with mixed flat/climb routes. Trekking bikes for day touring with light luggage up to 15 kg. Rigid mountain bikes for easy/medium trails without jumps. Class 1 e-bikes with assistance up to 25 km/h rear motor. Junior bikes 24"-26" for introduction to sport cycling. Vintage restoration projects from 90s-2000s maintaining period components.

Market alternatives comparison:

Compared to previous RD-TY18 offers 15% stiffer cage and larger pulleys. Superior to Asian clones for machining precision and component durability. Economic alternative to Shimano Altus M310 for those not needing 8 speeds. Performance comparable to SRAM X3 but with more available spare parts. Significant upgrade from unbranded OEM derailleurs fitted on mass market bikes.

Warranty and technical support:

Shimano 2-year coverage on manufacturing defects with online registration. Widespread service network at authorized dealers. Multi-language installation manuals downloadable from si.shimano.com. Official tutorial videos for adjustment available on Shimano YouTube channel. Compatibility verifiable with Shimano E-Tube Project app for custom configurations.
