Park Tool's TS-4 Truing Stand





FR-5H Lockring Tool



Anyone who's used a freewheel tool and big ol' crescent wrench to loosen a cassette lockring knows that while the combo works just fine, a one-piece tool would be much nicer to deal with. So that's what Park Tool made. The FR-5H is pretty simple: a long, leverage-providing steel handle is attached to a spline tool that's made to fit Shimano and SRAM lockrings, as well as disc rotor lockrings.



The head can fit over a quick-release nut (not that common on mountain bikes anymore but ideal when working on road bikes), and it's replaceable (part #2301) should you require a freshie after a few years of use.



There are other, more expensive one-piece freehub tools out here, but the $40 USD FR-5H is priced low enough for a home mechanic to consider, not just a bike shop.



Park Tool's FR-5GT



Another freewheel tool, this time one made specifically for bikes with 12mm thru-axles. The FR-5GT's blue post slides right down into the hub's center, helping to stabilize the tool from coming unstuck while you're pushing on the big wrench that you've attached to it. The twelve-spline tool fits all Shimano, SRAM, SunTour, and SunRace lockrings, as well as some similar disc rotor lockrings.



The FR-5GT, which is just one of a handful of Park's freehub tools, retails for a pretty reasonable $10 USD.

Bike shops that service a lot of fat bikes, or fat bike riders who prefer to get the job done on their own, take note: Park Tool's new TS-4 truing stand has been designed specifically for the job. Park's Eric Hawkins explained that while their normal truing stands can be used for fat bike wheels, depending on hub and tire width, the TS-4 has no such clearance concerns.The stand's uprights can be adjusted to fit hub widths ranging from 90mm to over 200mm by rotating the adjustment dial on its right side, which is wider than other truing stands and spacious enough to fit any width fat bike hub. The wider spacing of the uprights also means that they easily clear disk rotors, not something that Park Tool's other truing stands can say when talking about mega-wide hubs. A set of thru-axle adapters is even built-in, located just below the thru-axle slots.It's not just wide hubs that get along with the TS-4, though, as the feeler gauge's fingers are shaped to clear a massive 5'' wide tire. Park Tool has re-designed the arm's height adjustment system as well, with a true push/pull system whereas the setup employed on their legacy truing stands really just acts as an adjustable stop for the spring-loaded arm.The $350 USD TS-4, which works fine with normal hubs and wheels, by the way, will be available this coming July.
