SHIMANO genuine chain tool TL-CN28. * Compatible with 11-speed chains * Compatible chains: HG-EV / HG-X / HG / IG * Usable for both road and MTB bikes * Genuine Shimano tool, so it's highly accurate and can be used with confidence I bought it but never had a chance to use it, so it's been stored unused. Comes with the package (※There may be minor scratches due to storage). Instant purchase is OK. Feel free to comment if you have any questions.
