Dennis Stubblefield Sales Tool 40 | Chain Adjustment Tool

BBikes with single sided swingarms may not be all that common, but even less common are quality chain adjustment “spanner” tools. Some bikes will come with a chintzy stamped spanner in the tool kit. But some bikes don’t even give you that (ducati).

Dennis Stubblefield Sales is an american manufacturer of motorsport specialty tools - mostly flywheel pullers and stuff like that. But they saw our “how to adjust the chain on a single sided swingarm” video and reached out to us because they produce a very nice dual-head chain adjustment tool.

So why the dual head? If you notice, the two sides are different sizes to allow the tool to work on more bikes. he tool will work on virtually ever Ducati, most Honda’s, most MV Agusta’s, most KTMs and most Triumphs.

So, how does it work? Well, once you loosen the pinch bolts to allow the eccentric to rotate, simply put the spanner in place and rotate the eccentric.

We’ve been using the Motion Pro spanner wrench, and it works, but you’ll notice that it doesn’t fit perfectly on the eccentric, but the Dennis Stubblefield wrench fits much better and consequently, works a lot better. Plus, the material construction of the Dennis Stubblefield adjuster is of a higher quality than the Motion Pro. But, to be fair, the Motion Pro is listed a shock tool.

For about $30, this tool is well worth the investment. Plus, it has an integrated bottle opener so you can celebrate your perfectly adjusted chain with a bottle of suds.

We don’t know exactly how often we’ll use this as a bottle opener, but it actually doubles as a convenient way to hang the tool on a peg board for easy access.

Dennis Stubblefield Sales (DSS) or DS Sales Tool #40 Dual Head Chain Adjustment Wrench Fits most models with Single Sided Swing Arm System that uses Eccentric Hub to adjust the chain.
