Park Tool finally made a JIS screwdriver, plus more Eurobike tool highlights

2018 will be a good year for bike tools

Here at BikeRadar we love tools, and Eurobike is a prime opportunity to fondle the latest gizmos and doodads for fixing your bike.

We’ve rounded up some highlights from the show for you including Tune’s mad Linientreu laser derailleur alignment system, various Park Tool and Unior goodies, and a bonus item from Silca.

For full on tool geeks, Park Tool’s new sort-of-JIS standard screwdriver will be a must-have.

Although the precise definitions here are murky and the JIS standard as-was doesn’t exactly exist anymore, it is still the case that a traditional Phillips screwdriver is not the best tool for adjusting Shimano derailleur limit screws.

Although JIS doesn't exactly exist anymore, this is the head you need for a proper fit in Shimano's derailleur limit screws

A JIS (or pseudo-JIS) screwdriver has a subtly different head design which fits these screws far better, and avoids the risk of mangling the screw head.
