When the time came to add a chain tensioner to the Hubjub catalogue, the Singleator was an obvious choice. Surly stuff is good anyway, and this is a standout chain tensioner due to its almost entirely metal construction excluding only the jockey wheel which is plastic. You also get a forged alloy arm, stainless "cage", 11 tooth floating jockey wheel and replaceable spring, which we are happy to sell you. You can set it up to push the chain up or down, run 1/8" or 3/32" chains, and it copes with practically any chain-line offset. Requires a rear mech hanger and is available in black or silver.
