E-bikes do better with old school drive trains because the old cassettes are thicker and stronger and can handle the power of the motor which can shred the cassette cog’s higher gears if you apply too much throttle, even with a 750 watt Bafang. Plus, the gear spacing is is wider, hence less redundant shifting. This derailleur is basic and doesn’t multiple shift like the newer ones today…but it’s very direct and precise. I paired it with a Tourney 8-speed and and old SRAM cassette. Perfect shifting, no missed shifts or that grinding clicking ever. I also like the simple and elegant design plus that it’s a direct mount. Better than the Tourney with its extra mounting appendage. All in all, seriously good performance for the price. And…don’t listen to those bloggers that say just put it in a higher gear and zip around. It will destroy the teeth on the smallest cogs because of less contact surface. I’ve started converting my other builds to 8-speed drivetrains, too. Good luck on your bike builds! Review: shifts perfectly with MicroNew R8 shifters - I converted a Cannondale M300 (c. 1998) from a heavy, cheaply accessorized rigid mountain bike into a drop bar 2x8 gravel-esque road bike. I need a mid/long cage rear derailleur for the 50x38 to 11x32 gearing I would be using. I actually had to add a link to a brand new chain to get a comfortable length. After my first ride, the shifting seated the cable better and therefore my rear shift cable became super loose. Once properly tightened in the Claris, it has been shifting really well with $62.00/pair shift/brake levers from a Chinese company (MicroNew) who fashions their product after a similarly named company (MicroShift). Total bike build weight for an aluminum frame/steel fork, 26" mountain wheel with basic level everything else was just over 23lbs. Not bad for a bike where the only new item I purchased I actively sought something that was comparatively lighter than other choices were the tires (Michelin Country - Dry 2). At 600gms, these tires shed about 400gms/set over slicks or other low-depth knobs. The only tires that would have saved more that I would have selected were the Continental CrossKing foldables which are 430gms or so per tire. A last thought in regards to the derailleur is simple: if it's Shimano, all of the bolts are hex-keys, and it's for 8-speed or more, it'll probably perform well enough for anyone not racing the pro-circuit. ## Features - Medium cage length - Optimized for 8-speed road shifters, offering smooth and precise gear transitions with a maximum cassette size of 34 teeth for versatile gear ratios. - Medium cage design enhances chain stability and accommodates a chain wrap capacity of 43 teeth, ensuring consistent shifting across varied terrains. - Sleek black finish provides a stylish, corrosion-resistant look suitable for everyday commuting and leisure cycling, blending durability with understated elegance. - Engineered with 's advanced technology for rugged performance and easy installation, making it an ideal choice for entry-level riders seeking dependable drivetrain upgrades. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B073R1FKZP | | Best Sellers Rank | #287,334 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #248 in Rear Bike Derailleurs | | Brand | SHIMANO | | Brand Name | SHIMANO | | Case Material Type | Aluminum | | Color | Black | | Customer Reviews | 4.6 out of 5 stars 110 Reviews | | Included Components | Rear Derailleur | | Item Dimensions L x W x H | 10"L x 7"W x 3"H | | Item Type Name | Rear DERAILLEUR | | Manufacturer | Shimano | | Manufacturer Part Number | ERDR2000GS | | Material | Multi | | Material Type | Multi | | Model Number | ERDR2000GS m | | Mount Type | 10x1 Standard Mount | | Mounting Type | 10x1 Standard Mount | | Number of Items | 1 | | Number of Teeth | 44 | | Product Dimensions | 10"L x 7"W x 3"H | | UPC | 689228386082 | | Unit Count | 1 Count | | Warranty Description | Limited Warranty | ## Product Details - **Brand:** SHIMANO - **Color:** Black - **Material:** Multi - **Mounting Type:** 10x1 Standard Mount - **Product Dimensions:** 10"L x 7"W x 3"H ## Images ![Claris RD-R2000-GS Rear Derailleur - 8 Speed, Medium Cage, Black | Claris R2000-GS Rear Derailleur 8-Speed, Medium Cage, Black - Image 1](https://m.media-amazon.com/images/I/51+gRjx5xEL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent old school derailleur. *by G***A on October 10, 2022* I put this on my e-bike build.
