Park Tool TWS-3C Torx Compatible 3-Way Wrench
The TWS-3 is a Torx compatible 3-way wrench. T10, T25 and T30 wrench sizes in our classic three-way "Y" design. Useful for disc rotor bolts (T25), chainring bolts (T30), and hydraulic brake work (T10).
With this and the 2 Park hex 3-way wrenches, you can tighten or unscrew about 90% of bike bolts. I highly recommend having all three in the repair kit!
The Y handle design sure makes this tool a dream to work with. You are able to put just the right amount of torque on or off to get the job done. You have the 3 most used sizes right there in your hand...all at the same time. You need this tool, and you know it! You won't regret it!
I got sick of of using the little allen torx key that comes free with a lot of brakes/rotors. This tool makes installing rotors and servicing your hydraulic brakes a breeze. Its a park tool so its well built and worth the purchase. If you work with disc brakes a lot I would definitely recommend adding this to your toolbox.
