Shifts well and easy to adjust. ### ⭐⭐⭐⭐⭐ Great derailleur! *by D***N on March 23, 2026* I love this derailleur. It is comparable with their 11-38 10speed cassette if ran as a 1x with their 10speed shifter. It’s a great way to have a small mech that shifts well and is very easy to operate. Trigger feel is great ### ⭐⭐⭐⭐⭐ Gamechanger Bravo microSHIFT *by O***R on August 10, 2023* This super short derailleur with its 8 speed pro shifter has to be best shifting and range capability for cassette for a small wheel bicycle with a spring clutch. My bicycle was 16' inch Citizen Tokyo a small folding bicycle with a rim size at 305mm smaller than Bromton's 349mm. With a limited 6 speed freewheel 14-28 i wanted more speed and torque but need to install a cassette but no derailleur could fit since the Citizen Tokyo came with a super small Shimano Tourney. When i saw that microSHIFT made a super short derailleur for 20 inch 405mm rims MTB target for kids i wondered could i MacGyver on rim with 100mm less diameter than it was rated for? to push the limits of the cassette i used a 8 speed 11-32 oil slick cassette. Then after tuning and aligning the shifting it worked and with the 8 speed pro Acolyte trigger shifter it shifts like dream and the speed and torque gains make it a different bicycle from stock, as can go over 20 mph with ease and still be be able to climb hills thanks to range gains of the cassette over the flywheel. This groupset opens the possibility for small folding bicycle to quality derailleurs, shifters, and capability that true unlock the potential of small frames. ## Frequently Bought Together - microSHIFT | Acolyte Rear Derailleur | 8 Speed | Short Cage | Black | with Spring Lock - microSHIFT Acolyte Right Trigger Shifter - 1x8 Speed, Acolyte Compatible Only - DRIFT MANIAC 8 Speed Freewheel 11-34 11-32 13-28 13-32 Epoch E-Bike Sprocket 8spd --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/442662700-microshift-acolyte-rear-derailleur-8-speed-short-cage-black-spring](https://www.desertcart.hk/products/442662700-microshift-acolyte-rear-derailleur-8-speed-short-cage-black-spring) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-24*
