Blister Gear Review It’s a nice, compact, accurate, comfortable tool that’s quicker and easier to use when you need to torque a bunch of small bolts.
Pink Bike Review The ATD-1 makes properly tightening bolts a convenient task, but it's how its ratcheting internals function that sets it apart from some other torque wrenches on the market: you literally can't over-tighten a bolt due to the ratchet letting go at whatever value you've set it to....The ATD-1 is sturdy enough for day to day use in a busy shop, but it's small and relatively inexpensive, so it also makes sense in the garage of anyone who regularly works on their bike.
Velonews Review With burly, all-metal internal construction and ergonomic, composite-molded grip, Park’s ATD-1 is a solid addition to any workbench that sees carbon fiber bike parts pass across it regularly.
Cross Bike Review This little gem is smaller and cheaper than a traditional torque wrench and will last you for years. This tool is a must for any cyclist that has carbon on their bike.
Pink Bike: Best Gear or Accessory Nominee 2015 Park tool designed the ATD-1 to last in a shop environment, with all metal internals and a unique over-riding clutch mechanism that breaks free when the selected torque value is achieved, so the mechanic cannot over-tighten the fastener...it is easy to operate, and it eliminates confusion by offering only the five torque values commonly used on a bike.
Feed The Habit Review Let's face it... you need a torque wrench. You can't go any longer just guessing when it comes to the safety of all your carbon bits. This tool is overbuilt and confidence-inspiring. I like how it feels in-hand and how reliable the torque settings are, but unfortunately it’s not quite capable of being your only torque wrench — but it comes close.
BikeRadar Review Built in the USA, the ATD-1 is built for accuracy and durability. It’s high price and limited 4-6nm range makes it best suited to the enthusiast or professional tinkerer
