The TL-SH21 is by far the finest chain whip we offer. Quality steel construction is stout and will not flex. The sturdy plastic handle offers plenty of grip and features a hole on the end for hanging the tool on your work bench. The other end of the tool has a combo lockring/bottle opener.
The HG chain fits all standard 7-10 speed cassettes perfectly. Perhaps the best feature of the tool is the locking chain mechanism which attaches the chain back to the tool, so it doesn't float around when not in use.
