Chain Adjuster for Multiple Riders

The Chain Adjuster add-on is for trike riders with different x-seam leg lengths to be able to change the boom length, without having to cut the chain. If you do not have any extra chain to extend your chain length, you can add either a 9-speed or 10-speed chain to your order.  The 9spd chain is what the 27-speed trikes use, and the 10spd chain is what the 30-speed trikes use. A connecting chain link comes with either chain piece addition.
